In Fusion 360 to drive your entire design coming up.

Hey, Tyler Beck with tech and espresso today, we're talking about equations in Fusion 360. So check this out. I've got this model and it's a few sketches. It's a few different features. It's some fillets, it's a bunch of stuff. But if I come in and double click on this dimension, check this out. The whole thing is driven by one dimension. How do you do something like that? Let's go into it. Okay. First thing I'm gonna do is start a sketch. I'm going to sketch everything on the top plane for this example, and I'm gonna begin with a rectangle and you know what, I'm actually gonna search for my rectangles. And I'm gonna put everything on centered on the origin for this example. It's a good habit. If I want to put points right in the middle and keep things centered, that helps

 (00:59):

now one thing I missed when I did that. So rectangle center, and I'm going to type in those values right now. I'm gonna say it's eight millimeter by hit tab and then type in 15. I love that, that you can drop the dimensions really quick with the rectangle tool. Very nice. Alright. So what I'd like to do is drive this dimension based off of this one. So I'm going to click on it. And one way to reference the other dimension is to click the other. So it's going to write it in this. So this is called D two and I also could just type it in. So D two plus some sort of formula, right? So what do I want it to be? I want it to always be twice. So times two. Great. Now I'm going to extrude it. I'm gonna do D two and what I want.

 (01:55):

So it was eight millimeters. Let's say that it's always 1.3 times that side of that edge. So we just extruded it. Great. And maybe that's not quite what I want. So how do I bring up those parameters? I'll hit S parameters change parameters. It pops up this nice menu. Okay. I love this. So there's my equations that it's using. So like we were saying, we could have just brought it back up, but instead I'm gonna do, I'm gonna change it here. Hit. Okay. Next thing I'm gonna do. I'm going to do a shell thickness I'll type in shell. So as you can see, it's kind of using the same logic going forward. So D two and I don't want an eight millimeter shell, so maybe I want point, you know, 0.2 0.1. How's that look pretty good. Great. Now what about a chamfer in this corner?

 (03:03):

So that's 0.5. Let's do D two times 0.05. Great. Very cool. So let's go test it out. Say one little tip. If you right, click on a sketch and choose show dimension, it's going to wake up those dimensions. You do have to be showing the sketch, and this allows you to not have to go back in and edit the sketch to change the dimensions. I love this. You can double click and change this to 15. You can see the whole thing is driven from that. So that's a quick tip on Fusion 360 on parameters. I hope that's helpful. I'll see, in the next video.
