interpCurve3D on helix
I have selected an animated helix with an "edit spline" modifier on it.
classOf $ returns : "SplineShape" (what we expect)
interpCurve3D $ 1 0 returns:
"-- Runtime error: shape operation on non-SplineShape: Helix" (not what I expect)
How can I do SplineShape operations on the "edit spline" modifier level? (without collapsing it)
