Hi peter - the two smaller curves are open -( use `SelOpenCrv` and `CrvEnd/CrvStart` )

Hi Pascal thanks strange but maybe i don,t have seen this would be nice if we get e message for it
something like ‘not possible open curves’ maybe i don’t have seen this
but thanks Pascal !!!

Hi Peter - this is the current message -

“Curves must form closed planar loops.”

Good enough?
