Please, see the file attached.

The curve is a closed polycurve with 4 curve segments.

When I try to _Project the polycurve to the planar surface, only the lower curve is projected.

Please, see the result in the file attached.

It doesn't matter where on the polycurve I click to select it.

I stay in Front view during the whole procedure.

What do I miss?

Best regards,

Niels
