Scaling along axis

[Briaoeuidhtns]

I've imported a STEP file, and would like to stretch it along an axis. Is that exposed somewhere I'm missing? I've found .stretch on drawings, but nothing for Shape3D

This is a bit more difficult to do with the kernel in 3D. For these types of transformation, you need to transform the individual faces of your shape and build it back again.

This is what I did to build an ellipsoid, and, as you can see, this is not trivial. To stretch a sphere you need to:

• create a sphere surface
• transform this surface into a NURB
• transform the control points of the NURB
• build the solid out of the surface again

With a generic step file (i.e. a solid you do not control) the extraction of the surfaces and building back of the solid out of modified surface is quite a bit of work (if you manage to have something, I would be very happy to see how I can merge it back!)
