I have a part that I imported from an iges file. I did an check after import, no bad geometry or surfaces.
Saved it as a SolidWorks part.
I want to make create a sketch on a planer surface and but Solidworks won't let me. It's a true plane, no curvature, I used the curvature tool.
However if I pick a planer surface and use the reference command plane, it will create a plane tangent to, not parallel to the surface I've picked.
How do I get around this?
