I’ve encountered a bug in Rhino where the DirConstraint option in the SoftEditSrf command can’t be changed in certain situations. Here’s how to reproduce it:
- Run the SoftEditSrfcommand.
- Select a surface (ensure not to pick a specific point).
- Try to change the DirConstraint.
This bug has been observed in Rhino 7 as well. I’ve attached a short video to demonstrate the problem.
