I’m trying to split an ellipsoid with another surface in the attached file. When I do the split manually in the UI, it splits fine into two pieces, whereas when I do the same using the below script, SplitBrep returns a list of two IDs, but the second ID consists of zeros and doesn’t correspond to a visible surface in the UI.
Thanks a lot for taking a look!
