Hi Tom,

Thank you very much for the feedback.

Typically, I would also suggest exploring the DXF file export if Splines are already created (e.g., Edge Selection to Spline), but your model was not easy to transfer into 2D, and Illustrator needs to open it.

Sometimes Splines can be projected to a surface, but in your example, that might have changed the outcome (orthogonal projection vs. 3D/Perspective setup)

Cheers
