Rhino mac and 3d printing

i did a cone with the top and bottom open and cura is showing close top and close bottom. In rhino everything seems perfect how can i verify in rhino


If you exported a simple cone surface with no thickness, it is possible that Cura closed it automatically… You can’t 3D print an object that has 0 thickness…


But what is the best way to double the surface in rhino5

With a cone, you might try OffsetSrf (solid) or perhaps a Scale2D of the cone plus top and bottom PlanarSrfs…

i did a offset and i close my lines. You were right it work in Cura.

Very helpful

Thanx :slight_smile:
