(degenerate) Extrusion bug or?

[René_Corella]

Hi,
I have 3D polygon puzzle thing - trying to extrude each face, but one or more extrusions are ‘degenerate’ and I don’t know why. I don’t recall dealing with this before. Why is that? Extrusions move for some reason, instead of just extruding in place - thank you.
Have you seen this before?

Looks fine here.

interesting…

I keep getting the bad result, switched to ExtrudeAlong and used a line…silly - I’ll ‘re-wire’ the script - maybe my Rhino just needs a slap to wake it up.

Thanks @Quan_Li
