no loop through new edges and vertices error 1

[mikeglw]

I have a surface that I can offset the face in the positive direction. But when I try to offset in the negative, Keycreator
responds with : no loop through new edges and vertices.

I have tried several techniques to move this surface with no
luck...

Suggestions..

Without looking at the surface it’s hard to say why you’re getting the message. My guess is that the shape of the offset surface is distorting the edges enough to cause incomplete edges or gaps. If you offset a smaller amount does it work? Look at it this way. If you have a concave surface and offset it, you can go one direction forever, but go the opposite direction, eventually the offset becomes too complex to calculate so gaps are formed. Hope that makes sense.

Yes, moving the surface with smaller increments seems to
work.

The edge that had the highlighted problem is a compound curve
surface. Obviously ( well now anyway )Keycreator had a problem filling in the gap produced by the other moving surface.

Thanks for the suggestion!
