Hy,
I am having troubles when creating a extrusion profile.
When I add curves as inner profiles these will translate to somehwere else when performing the extrusion:
So, “Closed curve in the XY plane or a 2d curve.” means the inner profiles need to be oriented in the XY-plane relative to the XY-space of the outer profile! I had them all in the XY-plane, but didn’t realize that the outer profile defines the parameter space for all of the profiles in the extrusion. Makes sense now but almost drove me nuts… merci!
