Mesh part to geometry part 1

[jamescook]

Hi I am trying to convert an orphan mesh part to a geometric part. I have tried in Abaqus but I don't think it is possible. I am using CUBIT 12.0 to remesh the mesh part in question but it also is unable to create a geometric part. Does anyone know of any software that is capable of doing this?

You would probably need a point cloud tool in a CAD package to get a NURBS surface model. If you are OK with an STL, that should be an easy translation of the exterior triangles or squares. I hope this helps.

Could you please tell me what STL stands for? Thanks.

Search "STL CAD"

Below is the text file format for an ASCII formatted STL taken from:

http://en.wikipedia.org/wiki/STL_(file_format)

facet normal ni nj nk
outer loop
vertex v1x v1y v1z
vertex v2x v2y v2z
vertex v3x v3y v3z'
endloop
endfacet

Basically define a triangle by the coordinates of the verticies. Repeat for each triangle. It looks like a poorly formatted FEA mesh.

I hope this helps.

geomagic studio does that, but it's quite costly... ordinary cad packages (apart from MAYBE catia, nx) can't do that (without custom - costly - addons)
