Hello,

I am trying to convert a spline path into something more like a nerve bundle with multiple compartments following the path. ThickenWire works if I am keeping to a simple cross-section of concentric circles, but I want to move beyond that.

I've tried starting out with sweeping a circle along the path of the spline, but I get the error that the sweep results in a self-intersecting surface. How do I constrain the normal of the cross-section to follow the path as well?

And then with the next step in complexity, what would be done differently to sweep a cross-section template with multiple geometries along the spline?

My apologies if this is in the wrong section, but it seemed mostly CAD related to start with, and the tutorials I've looked at only import the geometry.

Extra points for the associated python scripting commands :)

Thank you.
