Hi Guys. Thanks for help i appreciate, that does shows me the issue in the imported file. The thing I wonder now is WHY does MOI import (from Illustrator as Copy/paste) those as broken non closed curves ? Is there "trick" to import geometry as closed curves somehow ? It's closed in vector software - right?

Thanks again
