I just did an offset surface on a rather complex piece of geometry in rhino. Once I do a clipping plane to create a section, what is the command to delete a surface so I can clearly see inside?
Easiest way is to sub-object select the surface (Ctrl/Cmd+Shift click) and hit the Delete button. If you want to keep the surface, you can use ExtractSrf instead.
Maybe use post titles that describe the issue, so that other users of this forum can benefit.
