Learn how to model the fixed controller with REVOLVE and SUBTRACT. Move the controller back and forth between the sketches as you model.
- [Narrator] The next element that we can model will be the controller up here in white. Let's make a new layer for that. I'll call it dash controller, and I'll give it different color. Maybe it will be green. I'll set that layer current, and right now we have, it looks like an open poly line. I'd like to have that be a closed object, so I'm going to draw a line right here, closing that off, and then I'll type J for join Enter And select the line and the poly line and press enter and they should be joined now in a closed poly line.
We can verify that by selecting the object and going over to properties and seeing that it says yes under closed. If it doesn't you can just change this from no to yes. Now let's go ahead and revolve this around the axle. To do so I'm going to click right on the UCS icon and then hover the cursor over the square grip and choose move origin only and then move the origin on the end of the axle. Now I'm going to go to the solid tab and use the revolve tool and revolve this object, Enter, around the central axis.
So I'll click this endpoint, and then I'll click this point below and press Enter to accept the default rotation of 360 degrees. Do we want to erase the defining object? In this case I'll say no, so I can maintain a copy of that closed poly line in the original location. Now I'm going to move this object over in the red direction 500 millimeters. Let's take a look at it over here now.
So this controller is an element that doesn't rotate. However you can see that it's interfering with the geometry over here in the frame. So we still have some work to do on the controller to subtract part of it's volume. So what I'll do here is say subtract, click on the controller first, Enter, and then click on this yellow element and press Enter. However when I do that, it eliminates that yellow element and I don't want that to happen.
It cut a groove in the controller, which is good, but I really need that element back. So I'm going to undo a couple of times, and then one way around this problem is to make a copy of this object. So I'm going to copy this object from this endpoint and place it back in the exact same location, and then press Enter to end the copy command.
So now we should have two objects there. You can verify that by trying to erase them. Type E Enter, and then make a crossing window across those and it should say two found right here. So we know that the duplication was successful. I'll press escape. Now I can do the subtraction just as I did before, but now we have a copy that remains. So now in this case, I'm going to move the controller back so I can work on it in an unobstructed view.
I'll move it back 500, and then I'll go over here and take a look at it. So now we have a groove cut in it and this gives us the information that we need to complete the design of this controller. I'd like to cut this curved segment away so that this is not just a groove but it actually is cut all the way back. So to do that I'm going to draw in a rectangle I'll type R-E-C Enter and draw a rectangle from this endpoint over some arbitrary size as long as it's bigger than this element that will be fine.
And then I'm going to extrude this as a solid Up a short distance. I will erase the rectangle and then I'll subtract from the controller, Enter, this new object, Enter. So now I've cut that away. That's the final design that I want for my controller here. So I'm going to move that back 500 millimeters.
