How to create outer boundary solid object

marek2M3E8 — Mon, 04 Jan 2021 15:37:41 GMT

I have created such a turbine:

Now I need to create a housing that will follow its shape very closely. I assumed that with the help of Revolve I would "spin" the turbine and create its solid shape, which I would then use for the cut operation in Combine. Unfortunately, body cannot be used for Revolve. Is there another way to imprint the outer shape of the rotating turbine on another object?

Create a sketch on the YZ or XZ origin planes.
Project (Bodies) the turbine to the sketch.
This will give you the outline.
Select all of the outline, then change it to Normal Construction.
Offset the outline for clearance.
Offset the outline for thickness of the housing plus the clearance.
Draw a centerline through the origin to the top and bottom of the thickness offset.
Revolve the thickness offset.

Thanks, I'll try.

It looks like, it is the way. Although projection is not as precise as rotation of the body, I can handle it. Thanks for the hint.
