Bug: Extruding an Arc

Grasshopper
1

I’m encountering what I believe to be a bug, but I could be wrong. What should be a very simple operation in grasshopper is producing an unexpected result. I’m trying to simply extrude an arc to make a surface. The resultant surface is not only an incorrect extrusion, but it has moved to an unexpected location. I’ve tried with different arcs and different extrusion vectors, and all produce bad results.

Anything that can be done?

Hi Andy -

You didn’t internalize the input geometry. This seems to work fine with an arc that I drew…

There’s been some back and forth with extrusion objects in Grasshopper. I’m on 8.19 for this test. Which version of Rhino are you running?
