Project 3D Geometry in API

[Anonymous]

Currently trying to find a way to project the 3D geometry of a bRepBody within the API (in python) so I can use it as a path in a sweep, I've read some posts on 2D sketch projection but haven't found anything to help with this.

I'm trying to project only the outermost edge of the helix (highlighted in purple) into a sketch, and then use this to create a path. I've previously tried to create a path using the edges of the body but this gives me a path composed of both the inner and outer edges, when I only want the outer edge.

 

Can anyone help with this?

You can use the edge directly to create the path for the sweep and there's no need to create a sketch curve.  However, in cases where you need a sketch curve for some reason, you can use the Sketch.include method.  You don't want a projection because that will project the curve onto a plane to create a 2D curve and in this case, you still want the full 3D shape of the edge, which the include provides.

After going back and doing some experimentation I've got it working with the edges now, thanks for the clarification!
