Offset surface with curved edges

Hello,

I have a surface with multiple curves joined together that I want to offset as one surface. The photo below shows the original surface and the offset surface, however when I used OffsetSrf it wasnt able to connect some edges. I changed the offset distance but that didnt change anything.

What is the solution to getting those edges to connect? thanks for your help.

Might need to fix those 2 naked edges first.

Funny. Can patch that surface in another cad package and offset without any issue. In Rhino the offset immediately creates a surface with naked edges again.

No issue in other cad:

Issue in Rhino:

Hi @user1238
Also, making objects almost 30 meters long with a tolerance of 0.001mm is just asking for trouble :grimacing: I would change the tolerance to something more reasonable, untrim all the surfaces and then re-trim them with each other. I’m pretty sure the offset will work better then.

Hey, I remade that surface by trimming with each other and increased the tolerance and it worked.

Thanks for your help @Normand
