[Salome] Howto export Edge-Geometrie from Salome to .eMesh?

Siassei · February 20, 2019, 10:57

Hallo,

I'm searching an workaround to get the edge geometrie of my STL-Mesh from Salome into an .eMesh file.

Edit: The script "surfaceExtr..." do not work good enough.

Any ideas?

Thanks.

You can create, in Salome's GEOM module, a group of edges (i.e. your intended feature edges), and then export these edges using a very handy Python script, which was posted in the Salome forum.

The workflow:

* Create geometry in Salome's GEOM geometry module
* Create a group of edges in the GEOM module
* Create a surface mesh in Salome's MESH module
* Create a group of edges in the MESH module with Group from geometry
* Select this group in the Object Browser and run this script with File -> Load Script
* Export the surface mesh as an STL file

This will give you your STL surface mesh, with the proper feature edges in an *.eMesh file.
