How do I change the baseplane (internally to the object) to be in the X/Z direction?
If I go into Plane persistent dialog I see World XY, but no other options.
If I delete that then the dialog box cannot be dismissed and Rhino/GG must be terminated.
Is there a manual somewhere that describes all these input types and documents each of the methods?
I would like to use this surface to trim a number of surfaces including the pipes. What trim would I use?
