Mesh part to geometry part

Mesh part to geometry part

Mesh part to geometry part

(OP)
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?

RE: Mesh part to geometry part

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.

RE: Mesh part to geometry part

Search "STL CAD"

Below is the text file format for an ASCII formatted STL taken from:
http://en.wikipedia.org/wiki/STL_%28file_format%29

 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)
