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

All the best,

Thanks for the file.

You need to find A mesh that allows you to render the Edges of the Stripe.
Which then needs an Edge Selection to define only the lines needed.

Loop selection allows for that. Store it, then deselect all, select all, use the selection Tag to select only the one you would like to have, and then invert the selection.

Example
CV4_2024_drs_24_STie_01.c4d

This selection (freshly stored/updated) allows you to render the lines needed. After rendered, Viewport can be saved as Illustrator.

Will this be perfect? I assume not. But that is the most I can get out of the file.

Cheers
