Blender for Engineers (step by step Guide)

1. intro to the class: So if you are an engineer or a stellar student in difficulty, so this course will be helpful for you. My name is character me and I will be your instructor in this class. I am civil engineer and I have experienced over five years in the field of 3D. We will take advantage of the modelling tools in a blender and start making mechanical drawings inside Blender using the native tools or three add-ons, no need to purchase and external software. You will learn, you will learn how to convert it to the layout to 3D drawings. You will learn also how to generate the blueprints from 3D model. You will learn how to import and export from etiquette or another 3D software such as Ryan also you don't have to model works to be 3D printing. Also, you will learn how to model vertex to be 3D printed, you will learn how to draw very accurately and efficiently. So this class will be published exclusively on Skillshare enough talking. Let's talk about the class project. 2. Class project: So I assume that you are watching this class on Skillshare. So zeros and a cluster brick. You will watch all the lessons one by one, step by step. And when you finish all the lessons, you will see that there is a new reference and there is an images in the source files. You just download them and start creating your own 3D model, then publish it in the class project section. And we hope you enjoyed this lesson. Let's talk about what Nick, just after watching this class. 3. cad modeling: Alright, soldiers is the second video. Today we're going to discuss how we can make these details. First two, I will add here. Let's see what we will get here. Let's make some loop cuts here. Using this is one method. Let's see what we will get. Some. Ruin. This vertex to vertex I will join using J. J. The J. Let's duplicate this one is towards thrush, which will be here. After that, I will upload the fire. Make sure that we have in any duplication is just fine. Assume that we have an circle or cylinder here, which diameter? It's something we can exist. I will make encircle. Went for its fine. Vertex was rowing 1625 to be here. Let's select all and delete. Let's see what we will have. Its took his team here at circle x and scale. If you want more space, you can scale. Z is areas scaled, shifted it. After that exit through scale. For a buoyant exit route. Let's say it will be one meter. One meter. We don't want to just be good to thrash. And let's see what we have. We can fill it. After that. We have something that we have here, Amber, if I say I mean zeros here for just went, we have this area. All of this. And scale it to six slides. Again. Here. Slide minus one to one slide. Let's see. We can make some significant, we can connect. Vertex of these surfaces we want to select. But again, we have two here. Vertex, vertex, etc. Finally, your silicon pole or physios pointers, circle. And I hope to figure how we can search for the 3D view port. Active vertex. To me, 24 maybe reduced to six. Excellent t degrees here, and etc. We have something we can point to. Here we'll be scaling or maybe four. We can go to an edge and adjustments will be one. Also will be here. The scale is a scale or rotation. So we may make it 1.1, which is one meter, ten, something like that. That's it. For now. I simply done it. To be here. To be here. We have something good to go fix. As you know what this is live session. And some problems may be helpful for you to know how to solve this. We have this model from scratch. Using only native tools. To solve for the adults. We can add luminal surface, and this will be fine. Let's see if we have a subdivision surface. I hope it will not crash. Just shift. See what we have here. Delete this vertex. Supposed to be. Here. We have no model from scratch. I hope you won't do any good tutorial. 4. simple model: Hello everyone, welcome. This will be the first reason a lot of training course and industries and when we do the basics of a blender, SVD, which is variant towards it. Basically we are here in the 3D view and by default should enable screen cascades. And if we go here in this, I mentioned, we will comes in. So this is the Render dimensions. We will not use it and this is about what we can go to. One also seen. We can prevent the units. We have unit testing, which is first one, which is the meter, and symmetric. Second is burial, which work very well. Which work very well. If you are using the American system. And maybe few inches or male, What we will work with the meters and this is the first step. We can find the dimensions here. And after that, we can go to start to add a blend. This is thirsty blend. You can go to Add, and after that you can go to the tool, the item, the Caesar to have dimensions of two meters. This is the x dimension of parameter. And in the y dimension. If you had any blend of five meter by meter type like this, maybe going which is 20 centimeters, you can work with centimeters. And if you're working with millimeters, you can work with millimeter. Maybe we have in the y-direction, maybe 100 millimeters. Clicking is a better zoom into our design. And if you work with microbes, can choose millimeter or micrometers. But I will stick to is a centimeter. We have some object mood and mood. And to exit route, you can hit E and exit route is a z-axis around 0.2, which is 20 meter is about we work on centimeter. Two centimeter. If you go to the item, will see that we have gotten to two centimeters. So let's type in something. We have an axis. Alright. So let's go to define how we can navigate inside Blender. Well, basically you can use the middlemost. We navigate, such as this. You can zoom in and out using your mouse wheel or Control and middle mouse by exist. If you go zoom in and DC is an issue, and they basically will go to the View and this clip start will be, moral, value exists and you are fine. Now see a new clipping issue. And if you go very, very small item getting distance, you will see that we have. You can go to one centimeter. The equipping issue will disappear. And if you are using very, very small, given this, you will see that you have the clipping, but you can't just take 2.1 and this will be fine for now. To start, you can also navigate like this and you can also rotate. You're using the mouse wheel and you can then shift middle mouse. To recap our lesson. If you wanted to zoom in, have two options is middle, mouse, zoom in and zoom out and also control. Let's go to then shift middle mouse, goes well then your scene. And to assume n with the most, to navigate through rotating using only the mouse wheel to zoom and rotate. This is a recap of our 3D view board. Let's see how we can select two. So we have here as 3D cursor. To define our 3D cursor in the viewport, you must go to select Shift and right-click this. And you will have the ability to go and deselect, define some locations like this. Also, you have the ability to add an object here, which is an ICU sphere. Let's add a cube. We have in here an a cubed. Let's delete this. We have here an a cube. This cube is around 0.4040 centimeters. And dislocation here, you can define the location z also, and also can define the rotation. Now, but we will make all the zeros. You can also align to view or to the world. This is very handy option which will generate UVs and they will explain it later. Anyway, we can know who and define is this cube. We go now, if you want to make this cube as the center, it'll shift to meet at the center and Shift S. This is very handy and you must remember that we have a shift as it is. You can say selection to cursor. And after that we will define how we can move and rotate and scale. We have here the move and you have the rotate and you have the scale to move. You can go to move in the x-axis. And also you can move in the y-axis and move in the z axis. Let's begin. What about our views for our review? And we are now in the front and you are now in the right and you are now in the top. And to be in the vacuole can control one, to be in the back. And also you can, Let's go here. You can control one to be in the deck, and control city to be in the left, and control 70 to be in the bottom. And also you can go here and click on this icon. You will go stereo it to be these views. Anyway, we have explained what our orthographic views. And if you are here, we are now an orthographic. And if you want to be in some perspective, you can click on this icon or simply click on the five, which is a short cut. You must remember 1375 to be as a perspective or to be in the orthographic. And also, let's see, unhide all our items of H2B to unhide this cube. And to be honest. So instead of the ears and version two, negative nine we have now is the outliner which is here. And you can rename this to be our first layer or to be designed earlier. And also we have is these icons you can rename it to be building. Maybe you can rename policies or ecosphere or sphere. Also, we have something. We have we have the auto lender. You can unhide from here. Hide or unhide like this, or using a shorter cut edge or Alt H that we have. Now the ability to add an item which may be and Torres, and we can move this to a new collection and the rename it renewed layer to exist anyway. Collection for now. To be honest, we can know, go to define the rotation and moving information toward this, our next lesson. So how we can move and rotate and scale or any item inside the inner tube. It is a process is very simple. You can move in 3D space like this. And if you have undefined, I mentioned you can in x around one centimeter and the G and y around 20 centimeter, and G and Z around 50 centimeters alike, exists as an ecosystem. To go further. And let's see how we can rotate. If you are now in the 3D space, you can rotate it like this. And you can rotate in x axis around 90 degrees and rotate and 45 rotate in the 45. And if you go here. In the item, you will see that we have is East dimensions with which we have defined earlier. If you make any custom dimension and you want to apply this rotation to be the basic original rotation you can select, Apply rotation and you will see that it is basic, is your basic rotation like this. Anyway, let's go to steep. You can now scale in the x-axis to be, to scale in the 0.5 and the scale in 23 times, like, like this. Anyway, let's delete all of these items. We have no excipient is a move and rotate and scale. This is a short-circuit, this item, and this is a selection. I will go to the center and selection to be the center. And this may be a table. So I will move into the z-axis around 55. And after that I will go to add a loop cut like this, and the scale ends the y-axis, such as this. Then I will deselect everything and the control bevel. This item. And after that we will loop cuts like this. And I will be also such as this. And then we will select, go to the fifth. So we haven't explained what is the vertex and what is the feces and what is edges. But basically it's the smallest unit in Blender is the vertex and this vertex. And this also will be phase, and this is an edges. This is our vertex which you can scale and you can move and you can rotate as you like. We will deselect everything and go to the face. Select this exit route around five. Not five, but we will GZ move around minus 15. So basically you have no stable. And let's go to apply for the file of those. Large will be five centimeter. This I didn't expect that will be a table like this. So as this table is what we get now, I hope you enjoy this first tier in vendor 28. In the next lesson, we will make our first mechanical drawing. Traditionally this course, you and then you can still zoom. 5. cad drawings: Welcome. This is lesson number two in our training course, 3D CAD drawing and sorry, blender to Monday. After we have explained the basic tool and soluble render, we will see how we can straight to make the first syndrome. But I have enabled this screencast case. And after that we will make our first drawing is a drawing for this will be the drug that you would exhibit, but we will start with this condition. And in this one, we will, which is in lift. Alright? So we will start from an Atlassian blend will be some dimensions. We can go here. And this electrodes emitter selected the meter for num to be better. And we can go to select it to be around, going to click here, its not one but 1.2222. After that, we can go to the z-axis around 0.02. After that. Maybe make this edge view ensure. Maybe in the item. Excellent. You see here we have 123 centimeter, which is 30 meter, but our NCR is ten centimeters or 200 central to how we will apply the scale. If you go back, we'll see that it around one to two centimeter. You can select this one. Before. We can slide to be here. G and X won't or two. No, it's executable and one to two centimeters. After that we will make a look at here. And we can go to scale in x0 and x1. Anyway. These essays, if you're sick living as usual as we can, go to the view for the mean and make a value 01. Then I will execute in the z-axis. Will be. After that, I will select all these phases. Extra tool in Z space and move in the z 0 to five. Alright, so we can go and add some loop cut. We are going to make this because we have a three hole here, one hole here and tools here. Basically, you can go to add an cylinder has videos of 0.05. Depths of mourning. Fourth vertex of 20. After that, we will be adding around. I will move here and rotate 90 degrees. Also. We will move shift to make sure that orients to Visa geometry. Then we have a who you will escape shift x, y-axis. Also duplicate it another time to know. And for Disease and Control J to be object and move, select all. In a way. Let's object to the Boolean. Select this one. Now we have this, the issue for this ASU to apply. Let's move it to be another collection. Vr2 maybe. Let's go to select and apply either to have guns. And this is useful. A subdivision surface. I have added the solute surface. You can see that our geometry or our object has been destroyed. And this isn't usually. We can add modifier. If you have some angles in your military is equivalent to work. We have no our std cout object and it can be 3D printed. It can be adjusted as you want. If you want to fix the angles. Are angles. You can see that this phase has as vertex of 37, Not only four or five or six. This is also in teen and also usually isn't usable. Object. If you wanted to. You can add some new code here. Going like this. I did this and also this. Anyway. Let's go back here. Let's try to add, Let's surface. This is English or no. And as you can see, this is the file which you have to admit. And let's see, this is our reference. The next lesson, we will see how we can assist you in this lesson. 6. another example: In about five minutes, I will show you how you can make an acidic CAD drawing using a blender. So the first step is to go to the meters and choose the metric or choose a centimeter. I will stick to be is a meter. To centimeter is this choice for you. But we will start from an oblique. This blend will be dimensions of x-axis, whereas the dimensions here in the item and in 20 centimeter, and it's in meters. And let's go back. Maybe in x is the meter. After that, we will go to a chooses the mirror. It will be something exist. Anyway, we will move to an energy axis, will be 20 something extra to it in the z-axis, around two centimeter. The other direction. We are now here. We have this one. And we will add some new code here. And if you want to use a distance from the sun, can select this and go as you want it to be usable. And we will apply the scale. Be Electric is one and move it away and move in the x around minus o, sound like is g and x minus 1.8. Like this. Anyway, we will select this face and this direction to exit route around point minus 125 minus z, minus 150, which is meter, will add loop and move to all the way down and move in the z whose centimeters and after the execute in the x-axis. We have now something we can know who at verbalize any room the fire can be applied in the mood. So we will add this little fire and select all and Alt M to merge by distance. Selected this one. This is anyway, we will loop cuts here. As you will see, a sky scale in the y-axis. Distance. After the loop. Anyway. Anyway, we'll select this one, but I will skip distance. Anyway, we will select this one. Maybe this electing and etc. In the z-axis. Z and z to z and z, two centimeters like this. After that, I will make will make something. We will select all these areas and go to abolish the scale and executing a lot. If you want. This around in centimeter or two centimeter, we will activate a G in this area and d z minus 1.5 centimeters. Like it is, we have no define this vector. In our lesson, we will make new better and choose a subdivision surface. And this is the benefit from making modelling. Then you can know this. All right? We have ability. We have made this shift. This is result of their surface here and after subdivision surface, see that we have the object is very, very nice object and as you can see, we have the basic tool would move scale inside. You would enter to build it. And we have this facility CAD drawing. And I hope you enjoyed this lesson. The lesson number four, we will continue our course and we can get new object lesson. The tutorial. 7. general shape precise also: What is a 3D CAD drawing inside the blender is 2.8. And this is lesson number four. And we're going to start Newton example. And inside this number we will see how we can make drawings. We will, we will stick. And this diameter, which is around eight centimeter, outer radius will be around meter. This will be around 25 millimeter. And let's go. All right. We will start to make a circle, and this circle will be 30 as a circular B32. And the radius, which will be, the outer radius, will be, we can assume N under 13. Also select all. And we want it. We can calculate for a moment I will in this video and now we have this. So we will have a calculated as the angle. You can go if you haven't in a calculator, we can rotate. First item view. We can also apply the rotation and the y. We will rotate this degree. Rotated it correctly. Or you want to make this minus four vertices and exit route and the z minus one to four. We'll change, we will change the dimensions institute. What I want to pick. I will select scale in this direction. After we have selected for edges, you want to speak to the z. Z to be. I think there is. Anyway, we can elect all these vertices and the scale shift towards it. We will go here. Amazon circle. This circle will be. Then we will scale, rotate around three. What is the value two? We will get, we will get, if you will. We will connect it. Right-click Bridge. Maybe selecting. We have basic vertice, what we find something we want to refine this just after. Maybe we can scale. After that. I will exit through the distance. Or if you want to be defined, we will, etcetera, rounded letter. After that. It's delivered. We have something. When we hear this vertice. Here. I will just scale this. Also. I have scaled on the z axis. This distance to be defined will select all vertices and scale on. Saying we can do here. But we will make only. But as a concept exists, we have no completed. And you can define a to be better if we added. We have if we added is this mucus we have recalculate. We'll select all define. Shift in. Our thinking is a source friends we have made. In this course. I will link in the description for this course. If you are watching. A course in Skillshare, can be scription for each lesson will see as a source files and we are done. We are done for the modelling. If you have any questions, don't hesitate to post it in the comments board. We will design. And as you can see, if you scroll here, we have a lot on design and August design. They have been for the weekend, start from the fourth lesson, and we will start from this number five. 8. how to draw complex drawings: And today we are going to see how we can draw this product or 3D cut inside Blender. Basically, we will use Blender three. You can use 3.2 or 3.2 or native tools will be used. You will use only the tools and the functions which has been existed in Blender, no external to get started. And we will make, firstly is I will make an arch. Start from n. Circle is a circle. Will be vertex has vertex around 40. And delete, Select All and move in the z. Is this vertex and extrude into z minus one to one minus 0.1. Is it the minus 120? We can click. Area makes the cursor to 3D cursor and scale. We reach this line. Selected, this item on this item activate, snapping, and move this to be here. I will exit route. And so Rowan to Mr. select this one and exit through the x minus three. This one also will be extrude and x1. After next something I will do it this first. We have an mirror. So I will delete, shift cursor selected and make origin to 3D cursor mirror of exaltation. We can select this one or this edge. A cursor will be here. Assume that you want is the radius to be two. So we will exit through the Shift S cursor selected and this vertex, it will be held before Hilbert. Select this edge. E to spend, let's activate the screencast. K is e. T. Start, two is 1499 t. Enable clipping, etc. We want some edges, etc. Here. We want 12345666 loops. Here also. We want six rooms. Let's fill this one. Again. Select two phases. And said Look, this edge remaining exists. Also. That's just one sink. We have made the assembly third. Then we can add in at any moment to weaken the cavity. I will add here. Do we need 1237 here? We don't need just one. Again. Again. That's fine. We'll have made something. Here. We have used this method because this method, we have met the radius to be 20 centimeter and we will make, it, makes the same here. But we can use the normal also. Because we have the same vertex. We can select this shift to the n is x and the control. Let's move here. Let's see what number of vertex we have. Here. Just statistics. We have here. I will delete these faces. And let's reach from here or from here. To make it perfect, you can calculate this distance from here. If we make, if we want it to be two meters. So we can select all and g and x. Sorry. This is two meter. We can exist. We can something. So let's duplicate the eye and we can use the volume. Let's cylinder scale. Alright. Let's save this one. See you again. We have some holds here. We show the clothes. I select this edge and fill few times. Make sure you have done, which is here. Again. Select some edges on the scale down. Also. This is one method. As you can see, it's not perfect. Before I move to first. See the result. As a result, you can upload civilian after select. Scale shift. Is it the bridge? This is unless it may work. Sometimes it may work here. As our sink. Normal. Normal is one sink. Also twice the full 3D printing. You can use it for three different tick. Right after that we have here and circle. This is one of the problems of reason Williams, we can look, we can't add, look at here how we can suggest we can use is a nice tool to add some loop cut tool again. To solve problems here. Fill again. I will fill this 1 fifth. So all of these vertex and lesson we will add details which is above. 9. What we have learned so far: So after watching this class, you will have learned a lot about the modelling tools, how to draw precisely inside Blender, how to draw very efficiently in a blender routing is a free. So if you want to take your skills to advance it, you can watch my advanced 3D product design course on Skillshare, or you can after that, which is an emission for rocks inside Blender. I hope you have enjoyed this class. See you in another lesson or another course.
