One input was not extruded because it would have made an invalid surface


(Carlvogt4) #1

I’m trying to extrude a complicated, closed curve. It is not a bad object, it’s planar, and it’s one object.

Every time I try to extrude it, I get the error:
“One input was not extruded because it would have made an invalid surface.”
I can’t seem to find a reason.

Any Ideas?

Can you post the curve in question? It may have some bizarreness somewhere even if it has escaped being labeled as invalid…

Here it is

The curve is not actually planar, it has one tiny area that has a vertical part, if you fix that, it extrudes fine.

Eliminate the little “V” part, replace with a line segment (or something else valid), join and extrude.
