After the “lightweight extrusions” update to the Extrude Component per WIP 8.0.23277.12305 the extrude component no longer accepts surfaces as a valid input and throws an error saying “1. Cannot extrude Surface geometry.”
It’s far from unique, I extruded a triangle onto a point and then try to extrude those faces outwards. All native GH.
What I found out which is super strange is that it works fine with Normal vectors from deconstructing a plane, but does not work with mesh normal vector… even though they appear to be identical. Also constructed lines with those vectors and they move just fine.
I believe I fixed this bug just this week. The fix should be included in the next public service release. I think Wim was just showing that in one of the newer builds that the issue you reported had been fixed. I think he only meant to encourage you to test out the newer build when it becomes available as we’re hopeful that this issue has been resolved.
