Extrusions - Fusion 360 Tutorial

- [Instructor] Making our triangles into solid objects is really simple, now that we've done all the hard work ahead of time. So each triangle is already housed in a component. The first thing I'll do is to hover over the name and then click on activate and I'll see which one I'm working with because everything else goes dim. Then I'll click on this button for extrude. And if I click on the interior, the program is smart enough to understand to leave those circles behind as negative spaces. Here in the dialogue, I can type in two millimeters and just confirm that the operation is for a new body and hit okay, and we should see that now there's a body that's associated with this particular component. The exact same steps work for the other component. So I'll activate that one, go to extrude and make sure I'm selecting the right area here. Here we are. Two millimeters as well and a new body. Great, now where things get a little trickier is when it comes to the struts. So the struts are going to be the kind of bars with holes in them that travel between each of these points of rotation. And I'd rather not have to do all this work over and over again. So now we'll take advantage of some of the copying and parametric features of Fusion. So to get that started, I'll right click up here and make a new component. And for now I'll just call this strut although we are going to rename these soon enough and I'll make a sketch on the X, Y plane but I'll do it off here in negative space. So I'm not basing this on any of the measurements that we've already made. We'll start off with two circles that'll be five millimeters in diameter and just use the grid and make sure that these are directly across from each other in a horizontal line. Now make a rectangular box. Again, not worrying too much about my exact measurements. And now we'll put in some constraints with the D command. Okay, so first of all, I want these circles their centers to be a certain distance away from the edges of the box. And we'll make that five millimeters. Because I didn't fix these elements in place, sometimes the circles will go scooting around and that's no problem. And I'm actually going to do something on purpose here that'll cause a problem later, so I can show you fixing it. So notice this dimension right here, horizontally between the center of the circle and the edge. I want you to watch that because it's going to get deleted in this process. Okay, I'll also have one going down from the left. And then this is interesting. If I go from the center and down to here, at first, it looks like everything's fine. But when I click, it says you're about to over-constrain the sketch, right? So there are lots of constraints that put in here so far. And at a certain point, if you have a lot of them if you have a ton of them they're going to start contradicting one another. So it gives me the opportunity to create a driven dimension which is simply a notification that a dimension is a current sides. However, I'm not able to edit it directly. So if I hit, okay, I can make a driven dimension here which is denoted with these parentheses. So while I can double click on this one and change that number I can not double click on a driven dimension and change it. That's important to remember. And then the last dimension I'll put in here oops, hit escape, is between these two centers like this. And at the moment that I can stay at 50 if we want it but this is actually a good time to check. So if I hit 40, I should see that the length of the entire strut changes, but the relationship of the circles to those edges remains the same.
