What you'll learn

Learn how to modify features quickly using design history. Continuing with the motorcycle cover design, you get familiar with History-based parametric modeling in Shapr3D and reorganizing steps to make features match your vision.

Welcome to part four of the cover series. In this video, you'll start to learn a little bit about the history-based nature of Shapr3D and how to manipulate features within the history. We're going to pick up right where we left off from part three. Because this sketch text comes after the shell, it's not going to be shelled out. Generally, fine detail such as sketch text and

fillets and any smaller features will come after the shell as a rule of thumb. Sometimes very small features can make the shell feature fail.

Now I want to put a cutout on one end of this to accommodate a shaft on the motorcycle. I'm going to open a sketch on this end of the part. Click on the top face, open a sketch, and get it positioned so it's easier to do this. I'm going to create a circle down on this end.

01:09

I don't want this circle to cut into the text, so I'll make this a little bit smaller, say 5.25, and I'll use a construction line to control this the way I used in the previous video. Click on the center of the circle, bring it over here to the origin, and click on the origin. Press escape to get out of the line command, and again to turn it off. Select this point and lock it down.

01:37

That's important. Also, I'll click on this line, convert it to a construction line, and then click on the line again to create a dimension. So this will be 14.25 and then exit the sketch.

01:57

And for this cut, we may have to select multiple regions. So I'll click in this area first, hold down shift, click here and click here. Then I should be able to drag this down, make the cut that goes all the way through. Now notice what's happened here is that I've cut through the shell and that may be what you want to happen, or it may not be what you want to happen.

02:27

In this case, I want the shell to go around that cut, but the shell is up here in my history and the extrude is down here. What we need to do is select the sketch plane and then shift select the extrude so that they both have these blue bars next to them. And then take these and drag them up the tree to before the shell feature. Now watch what happens when I drop that.

02:56

Notice that this wall is now solid. And if I flip it over, you can see that it's all shelled out.

03:07

So that's the power of having history-based modeling as opposed to just direct edit. With direct edit, something like that would be much more difficult to do and would require a lot more work. This is the end of cover part four. Please join us for the exciting conclusion where we'll talk about shell, fillets, and manipulating history.
