Error on using Offset tool (makeOffset2D: result of offsetting is null!)

Post by ismetacar »

Hello! I'm trying to create a toroid with layers. First, I drew my sketch and gave it an offset. Later I turn my offset to sketch (so I can give another offset to that sketch). While I'm doing this, I got an error saying makeOffset2D: result of offsetting is null!. I don't know how to solve this.

Note: I choose that method because after some offset on original sketch there is continuity errors on my later offsets.

It depends on the model. And in all the ages you have spent searching, you must have come across the saying: "no file, no image - no help".

Haha sorry I though the previous message was clear.

I managed to work a lot with the 2Doffset tool on this surfaces for instance:

And then when I try on these surfaces it doesn't work and I have the "makeOffset2D: result of offsetting is null!" error message. These surfaces are not bounded with straight lines, it is curved lines. Maybe that's why the 2D offset doesn't work ?
