Convert BREP faces to forms

Convert BREP faces to forms.

00:06

In this video, we’ll use convert, modify a converted face, finish a form and use modeling tools to replace geometry with a form.

00:16

In Fusion 360, we're going to start with a new untitled document and we want to create a box primitive.

00:22

We're going to start by going to create selecting box, picking a plane and simply making a rectangular extrusions.

00:30

From here, we're going to use create form and we want to use utilities and convert to convert one of the faces from our BREP body.

00:40

In the faces division section, we're going to increase these each to six with uniform division and say, OK.

00:47

What we'd like to do is make some modifications to the top of this design.

00:51

I'm going to begin by selecting a group of faces on the top of the design in the center.

00:57

I'm going to go to modify edit form.

01:01

One thing that we can do with edit form is we can hold down the alt key on the keyboard,

01:06

and as we begin to transform we'll create an extrusion off of that face.

01:11

Then we can use our other manipulation tools to scale them down and make adjustments to them as needed.

01:18

In this example, we're going to scale it down just a little bit making this rise in the center of the face.

01:24

From here, we're going to finish form and take a look at our Bodies folder, noting that we have Body 1 which is a solid and Body 2 that's a surface.

01:32

Let's hide Body 2, navigate to our surface tools, select the upper face and go to modify and delete or hit delete on the keyboard.

01:42

Then we can take stitch and stitch the formed surface and the original body with the removed top and say OK.

01:50

This will turn it back into a solid body.

01:54

This allows us to take the convert option, convert parametric BREP faces and then make modifications to them using form tools.

02:04

There are some instances where it makes sense to convert a single face and make adjustments just to that face,

02:10

while other times it makes more sense to create a complete form body and then convert it back to a solid or surface.

02:18

This is a basic example but this functionality can work across multiple complex examples,

02:24

and you can also use options such as modify and replace face to include the modified form face back to the original BREP body.

02:35

From here, let's go ahead and save this design as convert.
