View Full Version : Rail Extrude problem: flipping ~3/4 thru extrusion

I made a sphere and using booleans got a ring where it intersected an irregular solid. That I took that ring, made it a spline and tried to Rail Extrude a rectangle around it.

Unfortunately, about 3/4 of the way around, there was an anomaly.

Figuring 'who knows?', I deleted the 2nd half of the ring, Mirrored the first half's points, the side with ZERO issues, made a new spline and tried again.

Same thing (see pic).


what's the issue here?
how can it be avoided?

I know I can fix it by cutting and pasting, but THAT seems inelegant.
