Guillemot Posted November 24, 2014 Share Posted November 24, 2014 I've imported some NURBS created in MaxSurf, a naval architecture package, into Vectorworks. I would like to do some more manipulation. They come in as trimmed surfaces, even though I have not been trimmed them. Is there a way to untrim NURBS surfaces returning them to their "full" size?

Benson Shaw Posted November 25, 2014 Share Posted November 25, 2014 Untrim is button near bottom of OIP. The resulting untrimmed surface is usually a NURBS surface in the shape of the extents of the Trimmed version often a rectangle with some bulges out of plane if the source NURBS is not planar. Explain more or post examples if this is not what you meant. HTH -B Quote Link to comment
Guillemot Posted November 26, 2014 Author Share Posted November 26, 2014 If it was a snake it would have bit me. Thanks. That did untrim the surfaces. But it looks like Vectorworks can not handle the surfaces. When I hit untrim, the surfaces disappeared. The vertices remained, but the surface is not drawn. With one surface I was able to create an interpolated surface (Not a great representation), but the other it just gave me a "Create NURBS Surface failed" error. "Rebuild NURBS…" fails as does "Extend NURBS…" It think this likely relates to an ongoing problem I have had with Vectorworks from multiple versions back where it is unable to deal with NURBS containing congruent control points.

Benson Shaw Posted November 26, 2014 Share Posted November 26, 2014 Can you post a VWX file with an object you are working on, or a link to a similar example for import into VWX? I'd like to explore the surface and the problems you encounter. -B Quote Link to comment
