About This Class

Are you a Solidworks user with some experience in creating basic solid parts, but you find it difficult to model more complex organic shapes?

Have you tried other surfacing courses, but they were too theoretical, only explaining commands and their options?

From my own experience, the best way to learn more advanced modeling skills is to model real objects. In my experience this makes it much easier to understand how each command works and why to use them. Analyzing the objects also helps you understand shapes and how parts are built.

In this course we will model a pc mouse based on reference pictures. This model will require us to use surfacing tools and combine them with solid tools. This method is also referred to as hybrid modeling.

Join this course to upgrade your modeling skills in Solidworks.

1. Mouse 01 reference model: hello and welcome inside this course in this project, as you notice, will be modeling this computer mouse in general. When you model for for practicing, I recommend to use a reference that you can hold in your hands because this makes it much easier to understand the shapes in the details of your model. So in our case, let's take a look at some of these details. First, we have this transitioning surface which comes from this edge and blends into a top part off the mouth. And then we have this Phil. It'd edge that goes all the way from the front to the back and in the back area. It kind of dissolves and blends into this this back part here and probably the most characteristic element is this sideline, which is quite visible here on the side but dissolves in the front part. Okay, so I'm excited to build this model. I recommend that you build along. I have attached these reference images in the project area, so these images will be our starting point. And the first step we need to take is at these images as a background to our sketches 2. Mouse 02 settings: Okay, so now we are inside solid works. As you notice I have version 2020. Let's open up a new part. And before we start with the model, I just want to highlight some of the settings that I have here. So you noticed. I have this black team and if you want to set this up and you need to go the options and two colors and there you can find the background, which which is in defaults having set to light and you can set this to dark. Also, you can choose your color, which in my case, is set to classic. The default setting is more bluish color, and the classic is a bit more colorful. If you set your background too dark, you need to make sure that you go to color scheme settings and scroll down until you find you're feature manager designed tree text and make sure that this text color is set to light. So we go at it and set this to white or whatever bright color that you prefer, because otherwise you will not be able to see your design tree here in your in your view port. Also, you can notice that my Aikens are only Aikens without test. This is something you could set up under customize my Aiken. Size is medium and I don't use buttons with text. So this is unchecked here. Now let's go to our taps. Please check if you have thes taps, active features, sketch surfaces, direct editing markup and evaluate Mark up you don't need necessarily. But evaluate we will, we will use. If not, then you can go to tabs in your command part and just activate thes because we will used thes thes commands in scientist types. Also, I have some commands here in mine, in my view, command. But this is something that I will highlight every time you something here. You don't need to set this up necessarily at as it is in my case. For example, at Happy's Plane show plain settings, you can find them under under these high show items I could, so it's not necessary that you have to hear also, what I use quite often is normal too. Just look a man you can you can add to your view bar or just hit control eight, for example, that also works and also every command that I'm using. If you don't find it in your command, for you can search for it here in the search bar. So you need to type it in inside here, and then you can select it and use it. But all these settings done, let's start tomorrow and create the first catch on the front plane. 3. Mouse 03 bg pictures: So let's open up a new sketch on the front plane. And what we want to do is to we want to use images as a reference and placed these images on our sketch plane as a background. So for that, we we go to sketch picture again. This is a command that I have customized in my command bar. So you can search for it or you can find it also under tools and sketch tools and then sketch picture. So take that and I'll select this side you year. And the first thing we need to do is you notice this line here, this blue line, this is our scale Tool on. If we take this point and place it here at this edge, click and drag the arrow all the way to this edge Here we can add in a value which in this case will be 112 millimeters and the picture gets re scaled to this exact size. That way we need here. So no, What we have have to do is place it as it was sitting on the top line like this on hit. Okay, I'll do the same thing here with the side plane that's exit to sketch on Open a new sketch on the side plane. Import this view that's look normal to the plane, and this dimension will be 63.5. Okay, now, for this picture, I want to add a transparency. I notice here in the properties part, you can at an angle to your sketch if you want to rotate it. You can also add with or high to compete picture, and you can enable and disable your scale tool or your aspect ratio. Also, you can you can flip horizontally or flip your image vertical be and here down at the bottom part you have. You can add transparency. In this case, we haven't set to none, but you could add transparency for file. So, for example, if you have a new image PNG image with a transparent background or a tiff image and for ah , full image transparent so you can just set it up here to in disgrace, 40% transparency. You also have an option for user defined transparency, but this is something you can use if you have a solid one color background. Eso you get this color picker and then you can choose your background on, adjust your retirements and also adjust your transparency, as you can see here. But it won't work because we have shadows and too many different colors in this picture. So let's leave it at full image and set it to 40%. Okay, exit to sketch on. Let's do the same thing here on top plane and import this image here. You notice this one needs to be rotated, so let's go here. 90 degrees. Let's look at the sketch mole and use this scale tool to adjust the size 112 and that position the image so that is somewhat symmetrical on if you look at it from the side, I want this edge if it's projected down to the top lane to be coincident with this ash here . So I need to push this image back a bit like sold. Just check if it's it's still symmetric, okay? And let's add a transparency off 40% to it and conform exit the sketch, and I want to use in additional sketch here on the top thing and important this image here because we will need this edge for the very first catch that we are going to create. And the very first surface, which is just this side service here that's going up from this inch. So this image is is not oriented correctly. We need to flip it horizontally. Then we can use the scale tool also here. But now in this case will go from this edge to this inch and set the distance to 94 millimeters. Now we can position it, and I'm going to position this sketched in a way that this ash here lines up with the top U So, like like this. Okay, let's check it from from the side. So this edge here should be lining up quite nicely with this point. Not necessarily the case here. We need to remember that we have distortion in these in these images. So I'm just gonna push this image back a bit like this. And now these edges are lining up. Uh, so this will be fine. That's confirm and exit the sketch. Oh, we forgot for this image to seven transparency. And if you want to change anything with these images, you can open your sketch right click on this image and say feature properties. If you enter these feature properties, you can could change everything again. And here we go the full image and said It's 40% and then confirmed Okay, so now that we have our reference of it just set, we can create the first catch in the first lines and the frame for for our first surface. 4. Mouse 04 bottom part sketches: Okay, so let's start our first catch here on the top line. Let's look normal to the plane, and we don't need the sketched three here so we can deactivate. That's a top view. We only need this spot of you here. I'm going to work with a spine, So let's go to sketches and supplying. And then I want to create a sketch that follows this edge here, so I'll place the first point. So it's coincident with my front lane. Second point here, third point here, fourth and also the last one here, also coincident with the front plane, and it escaped. When we create these kind of clients, we need to make sure that we use as less points as possible in order to achieve the shape. This will result in better surfaces. So this is something that you always need to watch out for. Now, let's set up some some relations here that's click this handle and set this one to vertical . Same here for this handle because we want a tension transition when we really river surface that would create to be other side from attendant transition from decide to the other, and then that's manipulate these handles here. So we can we can come closer to two following this s u okay. And thats no this point here of it like that. Good. Okay. So we can accept the sketch on a side note. You noticed that this catch is not fully defined. So here you can see it's under defined. But this is kind of an exception that that we can make when, when we creates plans. Because maybe we we create a service with this plan. And later we want to make changes so we can go come back to it and just a justice sline in in a way that that makes the surface better. So it's not driven by dimensions like way. Or maybe you sue in creating sketches, but it's more driven by let's say how the surface looks and how we can influence the surface to get the result that we want. What I will do is still I'll just add a smart I mentioned to make sure that we have the right. Did I mention from here to there so at at a smart I mentioned and that's at this too 94. And now we connects it to sketch good. So for the first surface that we want to create, we will need some profile sketches. Followed this the shape off the bottom surface here. So for that, let's go in, go ahead and create a not a sketch on the front plane. Let's look at this plane normal. Let's use another Splain and we'll go from from this point all the way up here. And I want to follow this This call toward this shape here with this plan. So that's that's just manipulate his handle so we we can come closer to through the strait here. Okay, good. Let's, uh, that's at a lot of offline inside this catch coming from this point all the way up here, and the justice handles again like that. Okay, notice that I am atrocities plans a bit higher than than this surface. That is because I want to create a surface that that's a bit higher than that. This edge here and later I will trim it. So I would use the sketch, Ted, that will trim the surface here along along this edge here or this line. You notice that that the surface here on the bottom is a bit more rounded here at the back and a bit flatter he in the front. So in order to drive to surface into to achieve this result, I will need to more sketches somewhere around here and here, just to make sure that we have the transition from flat to more curved. And for that I would use to additional planes. Let's offset the plane from from the cycling here to front. You can do this by holding down the control key and just dragging new plane from the side playing to the front. And then we can have it. I mentioned here in this case will use a dimension off 35 millimeters. Okay. And we'll do the same thing towards the back. So hit control and drag a plea to the pack. And in this case, I want to have a distance. 25 millimeters. Okay. And now let's create a new profile sketch here on the plain one. Let's use this plan again. Just draw this plane somewhere on the plane and then we will set their relation from this point to this sketch, which will be a fierce relation. And then we we will look normal to do the sketch, and we know that this shape in the front is more more flat so we can adjust this displaying just a bit, too. Have a bit round. It's roundness to it, but not too much like this again. You notice I don't need or I don't work with dimensions. Here is, uh, it's more off a feeling that you that you have so that this is something you need practice for. And this is why I need to analyze your surfaces and try to figure out how these are built, how how we can build them, and you need to pay attention to these details. So, for example, that the surface here in the front with flat and you just try to match the floor surface and this is an interpretive process. So if you don't match it the first time, you can come back to your sketches, changed him and and just your your surfaces on that way. So same thing here for the back that sort of sketched there. Let's use this plying again. Let's look normal to the sketch. I'll use about about the same height office, and I used for first catch on. And this time I want to I want to be. I want to have pierce relation to the schedule. At this point. This is the wrong plane. Sorry. I want to look normal to this plane and I want to to have a somewhat more around it full file to to discover. Okay, lets that's right this way again. Notice. We will not be perfectly aligned to this image here because we we have distortion in these images. So again we just have to eyeball these the's shapes here and adjusting later if we need to . So let's finish this sketch. Let's hide the planes and also these images here and now we have the frame for our first surface as you can see, and creating the surface will be the next step. 5. Mouse 05 bottom part surface: Okay, so now we have our frame. Let's create our first surface, which will be a lofted service so well surfaces and click on lofted surface. And for this surface, you'll you'll need to add profiles and guide curves. So for for profiles will select this one. This will be an open profile, unopened loof, as you can see here, and you can confirm this will be the second, third and again, an open loop here. You can confirm this. This is because this sketch and this catch for this plying is inside the same sketch on the front line. So this is why the software, if you select this is a profile, will ask you if it's an open loop war closed toe. So just keep that in mind. And as a guide curve, we consider act this sketch here, you notice we already have our first surface. But we still need to add some some relations, some constraints. So we go inside here, open his options starting, and constraints and force thought start constrained. You notice we open this drop down menu, you can select direction, vector or normal to profile, and in this case will select normal to profile, which means that this surface is normal to the front plane because sketches the profiles created are on the front line, and the same thing will be using as an ends constrained so normal to profile here as well. No, the city's these arrows here. These are our attention length arrows on. If we increase that Harold, you will notice that we have a different flow off this surface. We look at it from the top. It's maybe more visible. You see that the surface changes, that's it. And this this handle at this front edge here to 1.5 and in the back also to 1.5. This basically increases the tendency that you have here. So the transition will be even smoother. And the surface you have you have noticed gets pushed out of it towards this edge. So, yeah, just, uh, it just changes to flow from from the mid part here, too, to transition to the side. Now we can exit the surface, my left, and let's go to evaluate and activate the zebra stripes again and just evaluate us our surface. If if we see any pinches or breaking in the surface. That's usually not a good sign. This means that the flow off the surfaces of a bit disturbed and this is this is the case here in this edge, if you notice. So we have a bit of tension here, says a bit too much. I would like to have a smoother flow from this front part to the side here. So in order to change that, now we can we can go back to our sketches and let's open this catch number five here, which is the bottle sketch that we used as a guide curve. And this is against something that you, uh yeah, you need to realize in time that these things like like this point, the handles or transition off this of this curve at this point will influence your surface . And just by looking at the surface, chances are high that this this pinching will come from this point here. So what I want to do is just release some tension in this point by releasing tension. I mean, I want to give it a smoother flow, so I want to to track these handles out of it, you can see the curve gets a bit smaller, so we don't have that sharp curve here in this. In this point, let's check if we are still aligning somewhat with with our edge. And if we're not, let's, uh, has tried to adjust it a bit like this. Okay, it's exit to sketch and check the curve again. Or check the surface again and you'll notice it's much better. So it's not. It's not that sharp over the turn here. Okay, so now we can be quite satisfied this food with this first surface and that shoulders aside to you again. What I want to do now is to create a sketch that follows this edge here and trim my service with that sketch. So show our planes, Let's go to front plain and open a new sketch. I'm gonna hide this service here and look normal to this plane. Let's use another is flying here and go from here all the way to the back to this edge. Now, at this point, I want to use a is for while sketch that we have already created, and I want to make sure that this point is coincident with with this splitting here like that Now we can go back to our sketch and the just ease thes handles a bit like this. Okay, good. That's leave it as it is. Yeah, that's exit this catch here, Skylar planes show the surface again, and then we go to surfaces on here. You can find this command trim surface. Then you can select this sketch here as a trip tool. You will see here and then you you can select your surfaces, the pieces you want to keep. So in this case, you want to keep the selections and then okay. And we have trained our surface. Now, looking at this surface, I see that maybe we are too, too low here at this A to this point. So you take a look at this edge in the distance to the bottom part. I think it has to be a bit higher so we can go back to our sketch, open it up. And just he was this point here, too, to get the surface a bit a bit higher. And the justice points again at, uh, at this point, you could You could use some sent inventions, of course, but we are orienting ourselves. Uh against our reference. So if you have a dimension that's a for for this height here, you can use that. But it's not really necessary. Okay, so now we have our bottom surface. The next one will be this side surface here, which we will create off with this edge. 6. Mouse 06 side area ruled surfaces: Okay, so we have our bottom surface now and we want to create this side surface here. And the way to do that is to use a ruled surface. He rolled surface is surface that that you can create using an existing edge off the surface like this one here and you have different types of ruled surfaces. In our case, this will be attention to surface. So if I click this edge, you'll see the surface gets created right away. That's at the direction to 20 millimeters. So we have a bit more highest here. And just to see what different options we have here, we have also the type normal to surface which, if we use that, you'll notice that creates a surface that is at each point following this edge normal to the surface. And we have a taper to vector type, which, what mean that you could you use a in factor. In this case, you will need to add a reference vector Here in this this box, the reference vector can be a plane or on access. So in this case, if we used the toppling, for example, you noticed this arrow which points upwards and that's the vector direction. This means you will get a, uh, surface that is following this vector direction and it and it adds a degree to the surface . So it's to this reference vector. So it's and each point of this edge. It's a 10 degrees to to this plane, as you can see here, and we will use this kind of reference tapered to vector command in a second step. So who come back to this later? Also, we can use a perpendicular to vector, which will be a flat surface. So it's It's always parallel at each point of this edge. It's parallel to to the stop plane and we can also use a sweep. So a sweep would mean that I have a reference factor which is in this direction. And this surface here is always followed this direction along this edge here. So it's basically perpendicular to to the top plane, but it could be a different direction, so we we could use on access that is at a certain angle to the top pain, so it would follow that direction then. Okay, so let's leave this one at a tangent to surface and exit this command, and I only need the front part. Off the surface, you notice that this is the area where we have justice edge disappearing. That is because the site surface and the bottom surface are meeting one surface in the front here. That's that's basically transitioning from from the bottom to top in a tangent way. So it's basically won't continue surface. And that's why we only need this tangent surface in the front here. And then somewhere around here, where Plane one is, we will cut the surface and the only create a transition to the backcourt. So let's take the first step and trim the surface. Um, but the trend is surface. I will not use a plane. I will use a different command because it gives us a better, more natural result. That's activate the surface and go to tools and on the sketch tools you'll find face curves . And this is a very useful command because it creates three these countries that are placed on your surface in two directions, and in this case, you notice. Here we have direction, one which are blue lion's direction, to which are these purple that were pink lines and we can add or decrease the number of lines that we want. Let's uncheck these direction two lines here because we don't need those. We only need this in this direction. Five curves are exactly right in this case because this is this is somewhere the area that I want to trim the surface. So let's let's leave it at five. Notice here you have these three these countries that were added to our, uh, future manager. I only need this one sketch. So let's select all the other sketches and hit delete. So I only want to keep this one. Let's hide this catch for a moment to to have a clear view off off the actual sketch we need. And now we can go to trip surface and use this curve to trim the surface and keep the front part. Okay. Now, for the second surface well again used this rule surface command, I can click this edge, but in this case, I will not use tangent to surface. I will use a tape it to vector, and the vector will be in this case. My I talked playing here. Okay, that's actus. Exit this cash for the Lord's command for minute. And that's activate our side image here, Actually, the back view. Let's look normal to to this image and let's go back to our feature through the rule surface and only checked the degrees so the degrees is set to 10 degrees here, and we notice that's maybe a bit too much. I want to follow this shape here, this decide profile. So let's try it with eight degrees or even 70 degrees. So now we see that we have come closer to to this orientation here and that's it. OK, so now we have or second ruled surface, and we need to trim that as well. Let's use the same, huh? Face curves here as we did before. Only this time I so I don't I don't use these pink lines. And this time I want to have a number off only four curves because this this is the area. I want to keep the back part, and from here we will transition to the front. So that's confirmed and I want to use only this catch and let's delete all the others. Now go to trim contributed surface 7. Mouse 07 side area transition loft: So now that we have the front part, that is attention to this bottom part here and the second surface which creates this edge. What we want to do now is to transition from from this surface from this edge here to this edge, the easiest way to do that is to go to to lofted surface and create a lofted surface from this edge to this edge. So these are our profiles on the guide curve will be this X here and then we need to add some constraints, which will be attention to face constrained and also attention to face at this side. So we have a surface that it's tangent to the surface at this edge, intention to disservice at this edge and follows this edge here. So let's see what the result is. Let's just hide these images. So we have a clear view on the surface and also go to just a shade of you without edges. So now you see, we have this effect here we have this edged. It's coming from the back and disappearing towards the front part, and this is exactly what we wanted to achieve. So that's change. The the shading to shaded with edges again just to see our surfaces. Let's, uh, show this image here from the side again. And if we take a look at our surfaces, we noticed that the height of the surface here in this area is a bit too low. So what we want toe have is really the surface that goes beyond this edge so we can trim it later. Eso what? What can we do in order to to correct this? Let's go to the surface here and edit feature and just add a bit off hide to it. Maybe 22 or 23 millimeters. This will be enough exit and noticed this transitioning surface gets updated. No, we have sufficient hype to be able to trim everything. Okay, so let's trim the surfaces with a new sketch that follows this edge here. So let's open a new sketch on the front plane and let's hide these surfaces. Okay, uses flying again. The first point will be coincident with this edge. Second point here, third point somewhere around here, it is important that this plein exceeds to surface so we can cut. It also would with this plane Now let's just the handle. So we become closer to the desired shape. It's like that. Notice that I following, uh, this bottom inch, but in this case, we need to change that, and we need to follow this upper edge here. The reason being is we, uh as we create this decide surface here, we will create different parts, a top part in the bottom part of the metals and the bottom part we will. We'll be cutting with a different additional sketch that will follow this this bottom each year. So no, we need to this edge to be able to create this side ball off the top work. So let's its adjusted just a bit more like this. If we want to make sure that this plein doesn't change and doesn't go anywhere, we can always click it and make it fixed. Then you notice it turns black. Since, uh, since I don't want to change anything on this plan because this edge here will not change, I can I can fix it and don't have to worry about about anything getting out of place. So let's exit the sketch now high thes plays that show these planes again How are these surfaces again? Okay. And this road surface also. Now I can use this created sketch and trim the surfaces. But it so, Tripolis, this one and I want to keep all of these and also the bottom part and confirm. So now, as you can see, we have this bottom part and also the side part, often off the mouse already created. And the next step will be to create this little cycle here which, if we activate this science, you you will see this is a the surface that is coming from this edge. And it's not a slight angle going upwards all the way to disrupt this year. You can see it more clearly. Maybe on this side. So it's it's this surface here. 8. Mouse 08 sweep, 3d curve and boundary: So in order to create this side panel here, off the top part, I want to create this catch on the front plane and let's draw a line, which is vertical, used at a construction geometry and use a line, which is it? Five degrees from my vertical line and his length off 3.5 millimeters. We can exit the sketch and hide or planes, and I want to use this sketch here, too sweet it along these edges all the way up to here that's also hired this side image, so we have a clear view on on our model. Now let's call the surfaces and Swept Surface. As for a profile that's select this catch and for a bath, let's right. Click in the selection box and choose the selection manager and choose all these three edges at once and hectic. OK, so as you can see now, once Web service has been created along these three single edges, let's speak. Okay, now let's go to the back, and now we can connect this edge and this edge with the boundary service. To be able to use a boundary surface, we need one more inch. So for this. I want to use a three decker. Let's go this cash click freely sketch and that's uses applying for this and thats click off this edge and all the way back here on this edge. Let's select disc line and set attendance relation to this edge. Let's look at this promise side, and I want to make sure that it follows this curvature here. This and so I want to adjust it just a little bit. I want to track it outwards to increase this angle. Let's check it from behind. So now it looks better to me if the surface at the end doesn't quite. You can always come back to this curve and adjust your handles a bit. And now let's go to surfaces and choose boundary surface. This really curve is already selected, so let's like this edge for Direction one, and I'll go to direction number two and selectees to edges. So the surfaces Albany created and we need to set one relation here at this edge. So here we can go to tendency to face and then we can take okay. Now we can move on to the next day 9. Mouse 09 top surface: Okay, so next we want to create this top surface here. For that, we will need a new sketch on the front plane, and I want to draw a slime that follows this shape at the top. So that's hold explains place. The first point here at this edge second point somewhere here at the top and the third point coincident with this edge. Let's look at the sketch normal and the just ease thes handles like that on like this. Okay, so with this catch again is under defined, you could add some dimensions if you probably want to 40. We find the sketch to these points. For example, here we can add 35 millimeters to this point on 35 at this. Now you can see the sketches fully define. We could still still these these handles here, so that leaves us a bit a little bit off. Freedom of movement. That's even that isn't exit this catch. It's hide these planes so we can have a clear of you. And also this side view here. So now that we have this sketch here, what I want to create is a loft which uses this profile and these edges, which are for now not connected. So what I need to do is to go toe curves, commands and select the composite curve and collect these edges to one complete edge. So select edges and then click. OK? And now I can use this edge here, which is the complicit curve as an edge for my for my loved it profile. So let's go to lost its surface now here the selections. Because I want to select this profile first and then the composite curve like that and select the guide curve, which will be this edge here. So we make sure that the service connects here to this image. Okay, let's add some constrains. That's at a start constraint at this profile here, which will be noble to full file like that and lets it. Okay, so maybe you noticed that Let's go to evaluate and just click on zebra stripes that we have kind of disconnect here. This is not a not a good shape. The surface is cut into two pieces, and at this transition you might notice a break in tendency. So this shows us that we have some kind of an issue at this edge here 10. Mouse 10 troubleshooting and wheel area: So we created this stop surface here and notice that way. Have a little bit of issue at this next year at this point because we have a breaking attention see on the break in this into surface here. So that's let's go back in history and try to fix this. Let's turn off the zebra stripes and I want to delete this top circus loved. That's also delete our composition curve. So what I want to do is basically replace or rebuild the surface, weep and replace it with a boundary surface. Because we used this edge of the surface to build. Uh, he's following sweeps and also this one. We cannot just delete it because then we we lose history for for all the following steps. So what I want to do is just hide it and keep it there in our design tree. And now I want to go to sketches. Let's go to the three D sketch and draws flying from this point to this point. Now let's add tendency relations here at this edge and also at this edge, and then we can go to surfaces and use a boundary surface to to build a surface. The first direction will be from here to this edge and second direction will be from here to this edge. And now let's add some relations here will be a tendency to face and also here tendency to face. Okay, Now let's see if we create a complicit curve again and create our loft if if we have the same issue or if we fixed it so this looks much better. This is exactly what we wanted. A clear, continuous surface between these two profiles and that was a guide curable. And this has here in the back like that, and the start constrained Normal to profile also what I want to point out Notice this notice that this surface here in this area is a bit flat. So there's a way to control that by going to thes tangent length carols this one here and increasing that edge just show even the surface shape from from this view and increased this tension length to 1.2. For example, this keeps you more a flatter surface here at the top and also work more kerf on here. Decide now we can't confirm and we have a nice top service here. Good. So that showed this side view again. What I want to create next is this flat surface here where the mouse wheel is and from there will be transitioning into this top surface. So for that, I want to start with a sketch on the front plane. That's just draw a line from from here to there and the second line from this midpoint perpendicular to our 1st 1 This will be a construction nine. Let's look normal to this catch, and I want to position it somewhat in the middle. Access off this wheel here. Okay, let's That's add a dimension, which will be from for this line here to top flee. And this will be an angle off 22 degrees. And let's add another dimension from here to the top lane. Let's set this to 25 the tire 27 and from here to DYS plane, this will be free. So this is somewhat in the middle of this mouse. Let's add a bit of heights to it. 27.5. Yeah, this will be This will be correct. Okay, that's add just one more. One more diet dimension to complete length That's sectors to 30 and exit the sketch. How I want to use this line to create the surface, which will be an extruded surface 10 millimeters in this direction will be fine. Okay? And I want to find a plane which is exactly on the surface. Here. You notice it's offset it to 100 millimeters. I don't want that. So that's zero here. Click. OK, and now I can draw you sketch on this plane on Let's draw streets, Love that's place thes first points coincident to the edge of the surface. And then at some dimensions distance between these two points will be nine millimeters on well as the radius off off, uh, for the half. Okay, that's activate or a previous catch. And I want to add a relation Coincidence relation from that midpoint off this slot to this point on that construction nine. So that's coincident. And now the sketches for really find and I want to add some offsets from from this profile . 1st 1 will be at 2.5 millimeters, and the 2nd 1 will be at seven millimeters like that. And that's it. The sketch that's turn off the plane so we have a clear view on the model and I'll use this catch to first trim this plane are surfaces extruded surface and keep these two elements. And then I'll use this sketch again to trim this top surface here and keep only this part. I see. Okay. And high sketch, because this sketch here and our image and now you see, we have this slot area is flat area. We can transition from this edge to here for this week would use a lofted surface. So let's transition first from here to there and at and constrained attention to face. Okay. And add the second loft here on reflection on this side from this edge to here like that and a tendency to face at the end. So we have to loft. And now we need a transition to fill this gap here. And for that, we'll need a boundary surface again. That's just clear. Selections select this edge and this edge and these edges here, the second direction service gets reoriented, and now we can add tension. See to face here also a tendency to face here and attention. See the face here at the bottom. Antique. Okay, So now we have a nice transition from from this edge all the way down to to this edge here into the top surface. 11. Mouse 11 manual fillet with boudary surface: Okay, great. So now we have our main surfaces done. I hope we need to do now is create this This rounded edge here, the top notice we have just they sharp as here and we want to round it off. And as we as we take a look at the backside here, noticed at this and this edge disappears towards the back here gets smoother and smoother, so there's a couple of way to do this. The easiest way, of course, is to try to just add a fitted to this edge. For that, we need to do one thing first. That's just hype this. Thank you. We need to go to knit surface to this command and connect the surfaces to one single surface network. Notice that we have these surface edges that are black. This means that the surfaces are connected at these edges so that we can try to use the fitted command and just click this edge to see what happens. Good. So we have ah, fill it. That's created. And let's see how how it looks. If we turn off these these inches and just click on shaving this thing, you will see that way have, um, a pretty the result that we wanted because we still see a sharp edge here. And if we take a look again at this side image, there is no sharp edge here. This this and she's getting kidding. Well, somewhat smoother and smoother towards the back. So we want something different here that's go back to shaded you with edges. Let's delete this. Fill it and actually let's try a different fit method here, which is the face fitted command, so called a fitted command again. And then click on face. Fill it. Try to, uh, yeah, he was Disc Amand to create a different type. So for faithful, it's you need to select face sets on. The one set is always on the other side, off the edge that you want to fill it, and then this other box you have to select the second side, which will lead this one notice stepped your fill. It is already created, but it's looking exactly the same as before. Now, with the fitted If the face fitted command, we have different parameters that we can set, So if you go to fitted parameters here, you can see this ascent to symmetric. But also what we can do is to send it to court with and normally in this court with will allow you to, um, to create a fitted that is constant and with so we say, this is two millimeters that these two millimeters are created completely over the complete length off the fill it. But this command fails. It's not able to create this fitted for us. So what other options do we have? Well, again, Using surfacing tools, we can create this. Fill it here manually, and let's remove this service that we because we don't need that on. What I want to use now is a sweat surface. So it's got swept surface and you will circular profile. The diameter should be set to three millimeters, and I want to sweep it along this edge here. So click that edge and you know what is the sweet gets created that follows this essential the way to the back that's speak Okay, now let's click on extent surface this command here and extent this edge by two millimeters . This is fine. This is only to make sure that to sweep really cuts the surface. All the way like that. And now I want to use this sweat surface as a training tool. So I want to trim these surfaces. So Swept services, already selected as a trend tools. I want to keep this surface and the surface is here at the bottom. Let's hide this, uh, to sweep surface and you notice what happened. Well, we can do now is we can create a transition from here from this edge to these edges here, and that's how we manually create off it for this. Let's try to do this first with a composite curve as a second, huh? Profile, which will use for a lot of surface. So connect all these single edges here. Say OK, and that's used a lofted surface from combat complicit curve, which is already selected to this edge. Here, let's check our results. As you can see, we, uh, we don't get the results that we wanted in this case. We need to we need to do some some additional steps and use a different tool. And for that way, we'll just use some three these catches to create our connections from from these edges to the edge. And she's on the top here. So let's create the first connection at this point, from there to there and at a tensions relation to this inch and up here to this image. Okay, that's exit the sketch and just click somewhere in your view, poor. Make sure that this camp, the last one is not activated and create a new three D sketch again. It's flying from this point to this point like this. Notice that I tried to follow the orientation off this edge here and now let's set some relations make tangent and also this girl we can set attention, See relation to the surface here, even if it's there's no edge in this direction. A good attention and exit the sketch. Same thing here at this point, display like this. Okay and said attention, See here and also to the surface exit. This catch can will need the last one here at this point like that said a tendency to this edge on to this face and hit. OK, okay, So our profiles are created and we have our composite curve down here at this edge. Let's go ahead and create a boundary surface and select this top edge here for the first direction and this complicit curve for a second direction. And now what we can do is select second direction, which is discover, if you first and disk Irv. Also this girl, This one and the last one here. So as you can see, this pond perfectly defines our are transitioning. Fill it so say fitted surface. They only need to add some relations here at this edge, which will be a tendency. And also here at this edge tangents you get. And now we can confirm we have a nice transition all the way from front to back. 12. Mouse 12 knit surfaces and create solid: great. So we have all our main surfaces done and the single surface missing Is the one here at the bottom being we will. It will create this one later how I want to mirror thes surfaces to the other side. And before we do that first thing to do is to knit all the surfaces together. So culture is knit service command. And this basically means that we will connect all these single surfaces to one surface network that is, that is connected. So select each and heavy surface here like that and those of his bottom one. So now we can move ahead and go to features. And on the linear pattern, we have the mirror tool and that's used the front plane as mirror plane and the bodies will mirror. He's this service knit. And before we had okay, you loan us under options. We had the option to knit surfaces together. So this does this mean that the original surfaces and the mirror ones will be needed to get her? In our case, this will be the middle line here, So let's get stood up for at the click had this option. So let's go back to options and click knit surfaces, and you'll notice now this line in the middle is also turn the black. Now let's close this, uh, body here at the bottom. Let's go surfaces and use play, not surface, and click thes two edges and hit. OK, now again, let's use the fit surface tool on Select these two surfaces, and now we have a different option because we have a close body. Now we get to create a solid model. So if you check this box here, creates salted and click OK or surfaces are created into or transformed into a solid moral . If we hit a cross section, you can see that this now is a solid. It's filled. 13. Mouse 13 shell and split solid: Now we have our solid body, which is we activate this section of you any full solid, and what I want to do now is go to the shelter man and create a constant wall thickness for this model. Let's tap at in 1.2 millimeters for the parameters and we are not selecting any. I just just enter the value and then hit. Okay. And as you can see now, we added a constant wall thickness for a cup tea party. That's exit this section, you and the next step is I want to create these two pieces we have. If we activate this this image here, you will see that we have the top part and the bottom part and this gap here. And also they are separated along this edge all the way through back. So it's, uh so our body again and I want to use to two sketches creating new sketchy on the front plane and use this sketch number nine on the sketch number two and copy these catches to our current sketch. It I convert convert entities said it both these sketches and click. OK, let's hide these original sketches. So we don't get confused and I want to trim them. I only want to keep the ones that are relevant for me, which is this one. And this one, frankly. Okay, exit the sketch. And now I want to use this profile to create a surface extruded surface. And for the right direction, I want to use a mid plane direction. So this creates a surface which basically cuts through this model from from left to right. That's hit. Okay. And now we can go to direct anything and use this split command. Use the service as a split tool. And on the target bodies, you you'll find two options, all bodies or selected bodies. In this case, we only have one. So we can leave that this setting. And then we can kick on cuff bodies and notice. We have two pieces now created from that one solid and the resulting parties. I can check both because I want to keep both and then hit. Okay, have the surface. And now if I Hi, this top part, you can see that I have the bottom part, has a single piece, and it'll sort of talk part at a single piece Now let's hide the top part for a moment and switched back our image. Decide you what I want to do next. I want to create this gap here. So for that I'll create a sketch that follows this edge at the bottom here. 14. Mouse 14 create gap with surface cut: notice that we have this this gap here in our model. So what I want to do is create a sketch that follows this bottom edge all the way up to the middle. And, uh, no, there it's just one continuous Edgemont following this, the same split line that we have used just previously. And with that news catch, I want to Teoh cut off a part of this this bottom piece here and create this guy. So let's start with in your sketch on the front plane and I want to use again this sketch number 10 that we have already created and converted. Copy it to our current sketch That's on hide these planes. So we have a better view, and, uh, I want to trim this this to this line somewhere here with just a simple, simple line. It's just fix it through some constraints. Let's make it cold in here with with the site clean or that's just added on dimension. Say this is five millimeters. That's where these two lines will meet. Let's add one more dimension just to to lock it in place. That's high, lower planes again. This will be a construction life and I want to trim this curve with it and hide this original curve so we don't have any confusions. That's high, this one. And I want to create an additional explain from this point to somewhere there in the front . Let's hide this, uh, this body here. I want to add a tangent relation, which in this case, for some reason, the reason well will fail. And I've noticed that sometimes inside, of course, we have an issue. I didn't quite figure out what this is issue was caused by, but if we have a a relation from from converted curves in this case, this is, uh, this one edge existing relation. Sometimes it doesn't allow to, or it reacts over the find. If we add if we try to attention, see? So let's delete delete that noticed that always get because under defined, that's fix it. So we make sure that it doesn't move anywhere. Um, that's just to beat dis constraint also. So we have a fixed I tripped supplying here and now we tryingto attention. See? Let's see if it works in this time. This time it works and just adjusted a little bit. Eso we make sure that we follow this this edge here and exit the sketch. Okay, Now let's show our bought apart again. And now we can use this. We can use this uric relate created profile to create a new surface. Let's change the direction to mid plane, okay? And let's use the service now to cut or for part on this case will be we'll be using a different command. This will be to cut with surface command. This surface is already selected because it was active. And now you just need to make sure that this arrow points in the right direction. So we want to cut off everything that's above the surface. So the arrow has to point upwards and we can change the direction by flipping this Aargh. And then you have the option to select your bodies, which you want to cut. And in this case, we have multiple bodies already in our model. So I like to select the binds manually. So uncheck this always select and then only select this body here and then click OK and notice The top part now is trip. So we fine show this subpart to see the get okay. 15. Mouse 15 create wheel and slot: now to create the slop here for a wheel, we'll use a already created sketch that's, Ah, use the sketch number 19 to show it and then sketch number 20 and let's Go the features and there used the ISC extruded cut command with this profile, and that's just say the direction one is blind five millimeters. But in the other direction and I'm gonna use a a draft, which will be one degrees. That's a check to the direction is correct. So I want to have this draft direction towards so at the inside like this and then click. OK, so now we have this. We'll slot now. We can hide this sketch and that's creating use catch on display in here. That's true. Our planes I think we have hidden are our play notices. Actually here, this is the plane I was looking for. So let's create a new sketch here on this plane. This will be just a long slop that's at some dimensions. The overall length will be 17 and go from midpoint here to get fined or two to this point on this line, this will be coincident and then and it's I mentioned for the radius. This one will be five. So we have Ah, 12 millimeter diameter for this lot. And let's hit. Okay, exit. I'm warplanes and use the extruded cut command again with this profile change direction and hit. OK, so in this case, as you can see, we, uh we were too short, but this cut extrude. So let's go back inside this feature and said I just want to 10 millimeters And also here that's selective bodies that be or we have to select the values that we come because otherwise we can cut into this bottom part. So you know, our cases already selected, So we have to confront and exit. No, it's now it's cut as it as it's supposed to be good and the next part we need to model is the wheel itself. So for that, I'm going to create a new sketch here on the front front plane. How did the plane? So we you can better see what's happening and use a circle. So Centrepoint circle and I want to place center point on this line here and just draw a circle. Let's look normal to plane on. Activate this side. You here and let's add some dimensions. So for the diameter, that's, uh, let's try 25 centimeters and see if we can match the contour here. And this seems to be matching quite fine. So let's have a new dimension. That's phone here to this line, just a fixed and in place will be 9.7. Maybe decrease the diameter just a bit 24.5 like that. And okay, next to sketch. As for the future, is now. I want to extrude from this circle mid plane, and it's going to be eight millimeters. Maybe with less 7.5 should be should be enough. And when we extrude on the wheel, we just have to watch out that this merger result boxes on checked. So we don't connect this body to the top part because now we want to add a fill it. That's just hide this real quick so we can have a clear view and let's add it, fit it, and in this case, we're going to use this full round fill it, which allows you to select four sets of faces. So in each box I'll select one face, and it creates a fitted debts, completely rounding off from one side to the to the other. So this is an elegant way off creating the wheel we have done. It's hard to sketch here and move on to the next part. 16. Mouse 16 cable and cable cutout: now, the less part I want to create is the cable that it's coming out from from the bottom part here and lives on the on the table, so to speak. And for that, that's let's create a new plane, which will be, at this point, attention to this surface. And let's open this catch on this plane and create a slot straight slob. You notice that we have this middle access here that we can use to place all points like this. That's add a radius of 15 So I want to have a diameter off three millimeters for for a cut out that's going to allow the cable to go through this report here on at one more that I mentioned Get to there, which will be 0.5. And let's add a relation from this point to this point, which we coincident actually changed this one here. This would be let's let's big Three. So we have a cable that's that's 40 fitting inside. This not here and then doesn't stand out. So this will be correct. Let's exit. Allow Eustis profile, too, at an extruded cut to the spot in part. So check all the selected. Always select. This is bottom peace here. Okay? And I'm gonna activate this sketch because I want to use it again. I want to use this point and create a new sketch on the front plane. And Ross Plein from from here, going through this point and and throwing inside the mouse like that, let's add some relations. I want to have this point at a certain distance from from our top lane, which would be That's what I mentioned there, which will be 1.5, actually. Welcome. Four millimeters, to be exact. Okay? And I want to add a horizontal relation to this handle just like that. Check this point out a bit and trust. Just handle here like this. Okay, That's as just another dimension to make sure that be, have fixed everything into place. So from this point to at this point, I want to have 20. That's a 24. Okay, Now I want to create a plane, are set to play from the toppling 1.4 millimeters on this plane or creating your sketch. How will the other planes now go from this point here? Just play some some random points for the cable just like that. And at one relation here, which will be tented, and we can exit this catch. Let's go back to this catch just one more time and track this handle just a bit more. So we have, uh um somewhat smoother curve here at the bottom. So now let's go to sweat, boss base, which will be a solid sweep and use a circular profile off 2.8 millimeters. And this is the reason why we have offset ID our sketch plane from the top you from the top lane with 1.4 millimeters. So the cable will be exactly placed on the top thing and I click this sketch here and through the same thing again. Circular profile, aids with this sketch here, just make sure again that we on check the merge result box because if this cable is connecting somewhere which it does to this bottom part, then we might have a problem. Good. And now, for the for the last part, we can go to direct editing and under combined kick this command, we can combine these two and only these two parts. So we have one on continues click cable and hide this sketch 17. Mouse 17 finishing touches: great. So we are almost done with our model. That's just at some final touches and something appearances that's building features and add some fillets here around this edge that's go to constant fitted and and if it off one point six to these edges and then add a new fill it to the sectors here. And in this case, that's had 0.5 and OK, and that's also fill it. This bottom edge here 0.5 will be enough. Now that's and some experiences. So we have a more realistic look to the model that's first selector the wheel and go to appearances, go to rubber and then, at this match, barber by right thinking it to the wheel, it's add a similar material, this glossy rubber to our cable and then to our top and bottom heart. That's shoes, a plastic textured plastic that's at this point here, the 2nd 1 from the top. This has a nice texture. Nice Chloe effect to it. Let's look at the model without edit edges. I just seen how it to note, so overall, I think we could be quite happy, uh, with the oval shape and these details we take a look at this rounded that's here on how it turned out. It's, uh, it's quite nice. It's dissolving as it moves to the back of the mouse. So it's this effect that we wanted to achieve. Also, this transition here, from from this edge down to the surface stop surface turned out quite nicely. I think the overall shape is also matching, uh, pretty good with with arm existing model with our real object and this highlight here at the side. I think this one turned out quite nice as well. We have a clear visible match here. We have to surround the shape at the bottom and this or flat shape here at the side on this edge disappearing. So I think we, uh we achieved the one is result here. I hope that you you could create the same result as well. I hope you have fun. I hope you have learned. I know just by taking one course, you cannot learn everything about surfacing. There's many more courses to come. So courses like this building real models. So if you like this video, if you like, this course will make sure that you follow my channel and you're welcome to write rating. And yes, so take care and see you next time
