How do I make one surface from a series of faces or surfaces

I have imported a surface iges file from Catia v5.

The surface consists of a patchwork of faces.

How do I make a single surface, with no reference to the original patchwork of faces?

I tried stitching the faces and doing a zero offset into a new model but the offset still had the small face relationship.

Obviously I am not concerned with any history and would prefer not to have to make construction geometry from the iges file as a basis for a new surface, they never replicate perfectly.

One of the things I want to do is to analyse curvature by creating planar intersection curves on the surface. Currently I can only get small face section curves, I would prefer one contigious section curve through the whole surface.

Zebra stripes are also affected by face boundaries making it difficult to assess.

My client is asking me to investigate why both Mastercam and FEM meshing are failing.

I agree, still need a methodology to get a single surface and contigious curves to analyse

We use a product called FormatWorks by capvidia to help import Catia files. You might contact them for a demo to see if it will do any better than what you are currently getting.

Here in the US you can email ...lyle at capvidia.be...just replace the word with the symbol and scrunch together.

Depending on the complexity of the surfaces, ACAD (MDT) can stitch the surfaces together with auto healing. You can then cut the surface with another surface and get a resultant polyline at the intersection, a usefull feature to get sketches out of a surface to use in SW.

If the surfaces cannot be stitched a brute force method of obtaing sketches can still be employed.

Phil,

It's a new subdivision surfacing algorithm incorporated into Catia, Ain't it just WONDERFUL, messes with your CAM system huh.

Seems those Dassault guys are always comining with new and creative way of making their stuff, incompatible with everyone else. Thought they'd finally come around with Ver5, but I guess they figured out a way to screw that up too.
