Issue with Lofting with 3 curves

Rhino Rhino for Mac
1

Hey guys, I try to loft three curves to create a curved surface but for some reason another surface is created (see blue arrow) and I have an open polysurface

I never had this problem with windows, but now with Mac.
Any advice?

Thanks,
Laura

Hi Laura - please post a file with the inputs to your loft.

Hey Pascal,

Sure !

so… two reds and one purple per loft? Use EdgeSrf for this, picking the purple first then the two lines, or ExtrudeCrvToPoint will also work, on the purple curve snapping to the apex.

Thank you ! EdgeSrf worked. I’m just wondering why it worked for Windows users with Loft. But it works anyway, so I don’t want to complain.

Best regards,
Laura

Hi Laura - you could loft to a point as well - purple to the apex.
