GDL: line elimination in tube and sweep

[jshuether]

I've tried scripting the same tubular shape using "tube" and "sweep."  Both results are not completely as desired due to the lines appearing in 3D. Is there anyway to eliminate these lines?

jshuether:

When using the Tube command, the only way I found to eliminate those "creases" is to increase the number of path points, so the path is smoother (higher resolution). Try adding additional path points between the creases.

create group for that shape and add it to itself, at least in ac24 it works

group "abc"
