I’ve been trying to extrude a projection in a new project and when I was unable to do so, went back to check in an old project (over a year ago) that worked perfectly well - only to find that one no longer does!
Has something changed in the app?
This worked before, as is evidenced in the photo.
Extrusion of a projected shape on a surface does work.
Try a simpler shape on the bowl first, as a test.
If that works you may have an issue with the vine shape.
My issue is that THIS design (and several similar) worked before but no longer.
The desktop app tells me that I cannot extrude from a non-planar surface - but I have plenty of older examples where I have done so.
