MeshToNurb or receiving different export format?


I Received a DXF model, but when i open it is build from 1000’s of meshes, MeshtoNurb doesnt do the job in converting this into workable surfaces. (it is in fact a paraglider model).

Any suggestions?
Does it get any different if i receive the model in a different format?
Is there a way to overlay with a surface, iow to copy the surface mor or less?

Most desirable would be to get the original Nurbs representation of the model, but if this is not possible, without more information on the exact shape, let me suggest this:

Intersect the mesh or meshes with a regular set of planes, for example using the Contour command, or by arraying a number of Plane surfaces. You will get a number of parallel Polyline curves out of this intersection. If you rebuild these curves with less control points and a degree 3 within an acceptable deviation, you can use e.g. Loft, Sweep1/2 or NetworkSrf commands to create an approximate Nurbs surface representation.

For complicated models that are not amenable to contouring this will not be a solution, but maybe for a paraglider it will? Good luck :smile:
