Draft angle analysis doesnt work

Draft angle analysis doesnt work … last rhino WIP build and macbook pro 13 M2.

Version 8 WIP (8.0.23136.12096, 2023-05-16) … still not working.

I’m having the same issues in Rhino 7. Are there any solutions?

did you try the add objects button?

works here- v 8.4

is this an extrusion object by any chance?
