Try also the Bezier Surface by Thomthom above, it's a true task! ☀

Good work.

So remember to draw on Layer 0 only, make a component or group of the geometry and assign a layer to that component or group and everything should go smoothly.

Thank you so much. I've been fighting this thing for 2 days. Should have asked for help sooner.

As Dave said... Small price to pay for free.
