Trying any part in a CAD program. So in the last section we chose a CAD program which is fusion 360. Let's jump right into it, go ahead and download fusion 360 and open up the program. So we've just opened fusion 360. So in this main area here is where we're going to create our part in 3d. Across the top, I have different menus, these are going to be to, to create create parts and also to modify parts or on the left hand side, I have a tree.

And this is where our origin is going to show up. It's where sketches two dimensional sketches are going to show up, and it's where different parts will show up. So if I'm creating a car, for example, all see a different line item for the car body and for the car tire for the car, rim, etc. So all the different parts are going to show up on the left hand side. Let's talk a little bit more about the Origin here. So the purpose of the origin is to define a zero point we're creating parts in three dimensions.

And our part is really lost unless we define the zero point, then every portion of our part is with respect to that zero point. So right now we're in three dimensional space in this room here. And let's say that we create this cylinder, this blue cylinder. If I'm in this room, and I want to, I want to describe to somebody else where the cylinder is, I need a zero point and that's where the origin comes in. The zero point is this black point here. Now from this black point, you can see that it's, it's in just a little bit from the back wall.

If I if I want to define where the blue cylinder is, I would say that it's one meter in the x direction. I could say that it's one meter in the y direction and two meters in the z direction. Now we've, we've defined precisely where the back portion of this circle And I could do the same for all of the different points of this cylinder. So now we, we can fully define where the cylinder is in three dimensions. And it's the same thing in fusion 360. So So I have my origin, I've drawn a blue cylinder here.

And the blue center is fully defined, the location of it is fully defined in 3d with respect to its origin. With regard to two dimensional planes, with this coordinate system, we also have 2d planes. And we're going to be drawing two dimensional sketches on these 2d planes. So this would be the Z y plane, it's just a flat surface which is defined by my coordinate system and this would be your xy plane. So every part is going to have its own origin and an assembly of parts is going to have its own origin. Now most of the parts that we're going to create are first going to be created into We're going to draw two dimensional sketches and then we're going to pull the 2d sketches into three dimensions.

Let's go ahead and do that. So we're going to go to sketch, create sketch, I'm going to click on one of the coordinate planes here, it doesn't matter which one right now. I'm going to go back to sketch and go to rectangle and click on one of the rectangles, I'm going to draw a rectangle and hit stop sketch to go back into 3d mode. And you can now see that I have a two dimensional rectangle on one of the planes. If I want to pull that into 3d, I go to create an extrude as the first feature that we're learning here, I can click on the rectangle, and I can either pull it with this arrow, or I can define a distance let's say one inch, and we now have our first part. I have a two I have a three dimensional rectangle Here, let's go ahead and drag over the top of this and delete it and create a different part.

Let's do the same thing sketch, create sketch click on one of the coordinate planes. This time let's go to sketch and creates a circle. And if I rotate right now, again, you can see that I'm drawing in 2d, I'm drawing as if I'm drawing on a sheet of paper. So I'm in a two dimensional mode. And if I hit stop sketch, I go from 2d mode into a three dimensional mode. So I hit stop sketch.

And you can now see that we have a two dimensional sketch on that plane that we clicked on. If I want to create a three dimensional shape, I go to a create extrude just like we did last time, click on the circle, pull it out, hit OK. And I now have another part that we've created. Let's drag over the top of that and delete it. So now let's go to sketch create sketch click on another coordinate plane, we're in 2d mode. And you can see so if I click the line command, this time, you can see that I can create any shape in 2d I can draw any shape, and I should be able to extrude it out and create a three dimensional part. So I've just used the line command, let's hit escape.

Right now this profile is open, let's close it off with an arc under my sketch tools, a three point arc. If I hover I get some directions here. I'm going to place the start point. I hover again it says place endpoint. And then I can create place the middle point. And let's stop the sketch to go back into 3d mode.

And I now have this two dimensional shape. And I can do the same thing, create extrude click on the shape, and I can pull it into three dimensions. So you can really create many, many different parts, just with just with the extrude command. Now I can also extrude on not just off of these coordinate planes, but I can also extrude off of any flat face. So I can actually click on this face, for example, go to sketch, create sketch. And let's say that we draw a wreck circle on that face, and I hit stop sketch, create extrude, just like we did before.

And I can pull it out. And what I've done now this time is I've drawn a two dimensional circle on this face instead of on the coordinate planes. I've pulled it out. And so you can see that we can draw any two dimensional sketch on any flat face to create parts. Let's go ahead and delete everything again, over in our sketches. Let's delete our sketches.

Now we're back to really nothing here. And lastly, with the extrude command, we can draw off of planes that we create ourselves. So let's go to construct an offset plane. And I'm going to click on I want to create a plane that's based off of this original coordinate plane. And let's just say I type in point three inches and hit OK. So now I have a new plane that I've created here.

And I can actually draw on this plane as well. So if I go to sketch, create sketch and I click on this plane This time, I can now draw off of this plane, and extrude from there. So this time, we didn't create our part based off of the original coordinate system. So so far, we've learned that we can create sketches on the coordinate planes on flat faces of things that we've already made, or on planes that we create, and then we can extrude them and create parts. So now let's use the same extrude command to remove material. So we have the same rectangular shape that we created.

And I can go in on this face, I can click on it, go to sketch, create sketch. Now. We're doing line off of that face. And I can draw any shape here. Let's just use the line command and draw somewhat of a diamond shape. If I hit stop sketch, I can now go to create extrude.

Click on my diamonds, and this time we're going to instead of pulling out to add material I'm going to pull in to remove material and hit OK. And you can see that we can remove material by using the extrude command which is called a cut extrude. So as a side note here, if we want to make changes to a part that we've created, there's two ways that we can do it. We can either edit the sketch in the trees, the left here, if I Go into this sketch, for example, and I choose Edit sketch. And let's say I wanted to make this diamond, a different shape, I could pull it into a different shape, stop sketch, and you can see that it changed. So I can either edit sketches in the tree to the left, or you will be editing operations or features down below here.

So if I edit this feature, which was my extrude. And let's say that instead of extruding the negative point 156 I just extruded say, point of five which would be halfway across the distance of this shape. You can now see that my cut doesn't go all the way through. So two main ways to edit things I edit sketches In the tree to the left, or I can edit operations on the timeline at the bottom. So as a review of what we've learned, we've learned about the coordinate system. So the products that we create in 3d are measured relative to this coordinate system.

And we can extrude or cut extrude by creating a 2d sketch on any plane or flat face. And the 2d sketches that we draw need to be closed in order to extrude them meaning that you can't have any open line segments of your 2d sketch and we can change or edit our parts either by editing the sketch in the tree on the left, or by editing the feature or the operation in the timeline at the bottom. Okay, so the next feature that we're going to learn is the revolve command, and it's also under the Create drop down. Just like with the extrude command, we're going to create a two dimensional sketch sketch, create sketch, click on one of the plans and let's see Draw a two dimensional shape with the line command. Let's draw a shape like that and you can see that we closed it off.

Let's exit 2d mode. We have this L shape on that plane. Now this time if we go to sketch revolve, it asked me what profile I want to revolve and I can choose what axis I want to revolve around. And I'm going to choose this axis here. So now you can see what we've done is we've taken our two dimensional L shape, we've rotated it in 360 degrees, and we've created this circular shape we had okay. And this revolve command is a very common way to create parts.

It's common to create washers or pipe cross sections or glasses. Anything cylindrical just with Like with the extrude command, we could extrude and we can also cut extrude with revolve command we can cut revolve as well. Let's go ahead and do that. So let's go to sketch, create sketch. Let's draw on this plane here. I want to get a, I want to be able to see through this part when I draw this time if I go to display settings, and let's say I just do a wireframe, so now I can kind of see through my part, just so I know where I am.

If I go to sketch line, let's say that I just create a small triangle here. Make sure that I close off on my sketches. So we've created this triangle. I'm going to exit 2d mode. Let's get our view back. Now what I'm going to do is revolve this triangle around to cut out Some material.

Let's see if it works. I got to create revolve, I click on the triangle that we just drew. I have to choose the axis that I revolve around. And you can see that it cuts out material. So our review of what we've learned here, we can create parts with extrude and cut extrude. And we just learned that we can also create parts with revolve and cut revolve, to learn two more features that are going to be very beneficial to us.

I'll see you in the next section.
