About This Class

Exploded view drawings are used by industrial designers, mechanical engineers, and patent attorneys to illustrate all of the parts of a product, and how they are assembled together.

These drawings can be generated from computer models; but drawing an exploded view based on the principles you'll learn in this class is much more efficient and faster to produce, especially in the early stages of product development when you're trying to sell an idea, and there is no 3D CAD data or computer models created yet.

Once you're done with all of the lessons I hope to see your own exploded view in the class discussion so I can provide feedback and help you improve. 

Happy sketching!

1. Intro: Hi. Welcome to my skill share class. Hopefully you've seen on my other skills share classes of this point. But if you haven't my name is Federico Arias. I'm an industrial designer and consultant, and I work with companies to design and help bring their product ideas to market. My specialty is in visual communication and in this class will learn all about a technique that is very useful to master. For any industrial designer out there, Exploded views exploded. Views are a technique used by industrial designers, mechanical engineers and even patent attorneys to convey and illustrate all of the parts and components of a product and how they are assembled together. Sure, you could model every component and cat, create an exploded view state from the assembly and then generate an engineering drawing from that. But drawing an exploded view based on the principles you learn in this class is much more efficient and faster to produce, especially in the early stages of product development, when there is often no cat created yet in this class will go over a cross section view analysis of a product in two dimensions. How to break up internal components into groups to make them easier to display. How to get the ideal perspective for exploded view drawings. How to take complex shapes and simplify them into their primitive shape envelopes, Which makes it easier to translate to a perspective you composition. How to arrange and refine internal and external components for the best visual communication. How to beautify the drawing with color blocking, shading and highlights. And, lastly, which supporting details to use to really make the drawing pot like directional arrows. Component labelling and feature Call it's. Here's a look at where you'll be able to accomplish by the end of this class. Once you're done with all of the lessons, I hope to see your work in the class discussion below so that I can give you feedback on your project and hopefully help you improve. Also, feel free to ask me any questions about the class in the discussion as well. All right, let's move on to the next video to get started 2. Cross Section View: Okay. Hi, everybody. Welcome. The first thing we need to do for this exercise is pick a reference object. Now, here, I'm going to be using a Cordless drill. Why am I using this object? Well, it has a two sided housing component, which is the outer part. Comprised of multiple textures. You got texture plastic, which is the orange part and a rover over mold, which is the grip. You have actuacion components, which are moving components comprised of the trigger, the battery latch, the chuck where the drill bit goats etcetera. And you also have internal electromechanical components like the motor, the gearbox on the trigger switch. This object is complex enough to get you a very compelling expletive. You drawing out of it, but simple enough to wear That doesn't have way too many farts. If this is your first time doing an exploded view drawing, I recommend working with a product that already exists so you can keep referencing it. All right, let's go. Okay. First thing we're gonna do is draw a side view of the product to get the proportions right . Keep this one nice and fast and rough. And once we have that nice, rough side view. Let's go ahead and clean it up and do a more final line work over it or, as I like to call it, refining your line work and getting the line weight right? Okay, once you have a side view drawing that you're happy with and has the correct proportions, let's talk about a cross section view, which is a crucial referential step to help you get a correct perspective exploded View out of this product. Okay, let's picture a Cuban three d space that has an access dividing it right down the center of it. Now let's picture an invisible plane that is cutting the Cuban half right across that access and then picture just the 1/2 that's further from you. That stays. Know what this cross section plan is doing Isnot only cutting the object in half but also allowing you to see inside of the cube. Half that it's left over. Usually also refer to ask the housing. Now, this is a three D representation of what a two D cross section view plane does for you, and this will be the basis of our next lesson. Okay, In order to get a cross section view of this trail that we drew. Let's start by getting rid of all the internal lines, and that's going to be the basis for all the lessons coming forward. Okay, and this should be the basis for your cross section view of the drill Drawing in the next lesson will explore had to add the right material thicknesses. How to add crucial assembly features like ribs and bosses, the rubber over mold around the housing and how to depict and group all the internal components as well See you on the next one. 3. Internal Component Breakdown: Let's take the side of you sketch. We did in the previous lesson. I'm populated in order to get a true cross section view of our drill design. It really helps to find a reference image of an existing product and analyze it to really understand which components make it up, how they come together and how the internals air designed. We'll be using this reference layout in our cross section view. Moving forward. First thing we'll do is draw the internal components where we think they should fit color coding and separating these components into coherent groups will help with our exploded view later on. Once we have all of these components all drunk, it really helps the label, all of them for reference. You should end up with a drawing like this after that would place bosses on the inside of the housing. These will help line both halves of the drill, and also the bus holes will receive the screws that hold the whole product together. Next is adding the material wall thickness. This should be even throughout, and then we'll add ribs. These were slightly thinner walls that support the bosses in place. An ad rigidity and structure to the housing. And lastly, we'll sketch in the over mold area, which is the rubber grip that gets molded on top of the plastic housing that should be your end. Result in the next lessons will take this completed cross section view and learn how to translate all of these components into perspective. Use to make a true exploded views catch. See you then. 4. Ideal Perspective: Now that we know how our drill will look like inside of the housing and how the component groups will be laid out, we need to pick an ideal perspective for our exploded view. We'll be using a moderate perspective or, in other words, a simple two point overhead view. This kind of perspective, as opposed to an extreme foreshortened perspective, for example, allows for several things. First, it allows you to look inside the house and components from a few different angles. But most importantly, it allows you to explode or separate the components in three directions or all three X y C axes of all three dimensions. You should always strive to explode parts in the same direction as the perspective and use it least two directions to add visual interest and to avoid confusion. Okay, the next thing we need to do is figure out the primitive shape envelopes of the component groups. The's air, the simplest geometric shapes that are component groups will fit in. The drill body fits in a rectangular box, and the motor gearbox module will fit inside of a cylinder. Having these established will make it much easier to bring these objects into the perspective rule we established before by simply representing these two D envelopes in their three D forms. In the next lesson, we'll learn how to subdivide and refine these shapes to start defining our final components . 5. Subdivide and Refine: Okay. The next step is to start subdivide in your primitive shape envelopes and two D or cutting away parts one at a time until it resembles your object closely. I didn't do the same cuts to your shapes in three D. Keep the lines rough at this stage, and don't worry too much about how it looks. Staying true to the perspective is the most important. We'll do the same with the motor module here, which in three D translates to a serious of subdivided cylinders. Start by drawing each objects rotational profiles and then draw the ellipses for each cylinder shape. We'll follow the same rules for the remaining components. Staying true to their color coding toe. Help us stay on track. Do this for your trigger switch, the battery connector and the pull trigger. Next, we'll separate the housing and exploded into its two halves and roughly subdivided shape and three D. Remember to always reference your cross section view for details and proportions. Okay, here's a summary of this whole process 6. Commit and Clarify: Now we'll lower the A pass ity of the previous rough layer and start to finalize our housing shape. Remember to be mindful of the wall thicknesses and boss and replacement. Next will arrange are color coded component groups to make sure everything is clearly visible. Then we'll start a new layer and commit to our final language. Then it's color blocking or filling in each shape with a solid color. - And don't forget the rubber over mold for the grip area. - Next , we'll do some shading to add depth and volume and then highlights to establish a light source. - Oh , and finally, let's do some hot spots on the part line gaps to make sure everything pops. You should end up with something like this. 7. Final Details: Okay, The last thing to do is label all of your components. It really helps to have a bill of materials or an inventory sheet off to the side just so that you're drawing doesn't get too cluttered. And that's it. Awesome. You've made it to the end of the class. All right, let's take a look at what you've created so far. We learned how to do a cross section view of our design, then refined and group the internal components added bosses, ribs and material thickness to the housing. Learned about the ideal perspective you to use for exploded views learned about primitive shape envelopes and how to translate R two D components into three D views. We refined our shapes and get the right composition. And then we did the final line work, color and details to really make this exploded. View illustration. Stand out. I sincerely hope you learned some new techniques on how to take your product design ideas and generate exploded view illustrations from them. This exercise should also give you better insight into how most consumer products are designed and assembled, which is a great added bonus.
