I have a surface triangle mesh generated by myself. I want to be able to use GiD to convert it to IGES format. The import of the model into GiD is fine, but when the model is exported as an iges file, the file is almost empty in that there is no geometry information or others. The attachment is a testing example. Any suggestion on this?
Thank you
Henry

The mesh triangles are not written in the IGES file, mainly this is a geometric format.
Can convert each triangle to a geometric surface:
1- Export your triangles with the auxiliary template DXFSAP2000
menu: Files-Export-Using template (only mesh)-DXFSAP2000
2- Import again in GiD this dxf file. You will have a surface by triangle
menu: Files-Import-DXF
3- Export finally this surfaces as IGES
Regards
Enrique

Following the steps you suggested as below, I am able to convert a surface triangle mesh (generated by another lcoal programme) to .iges file format. The problem is that the corresponding .iges file contains only point coordinates and line definitions without surface element definitions. So this file can’t be used for 3-D mesh generation. Any suggestion on this problem?
The attachment is the test model and its corresponding .iges file.
thanks

The surfaces of your test.gid model were not written in the IGES file because they are ‘surfmesh’ entities.
A ‘surfmesh’ is a GiD pseudo-surface (with a mesh to define the internal shape). This entity cannot be translated to any IGES entity, then only the curves and points are written.
Don’t import the triangle mesh with Import-Surface mesh (it create ‘surfmesh’ entities)
You can use my related trick:
0- Read your GiD ASCII mesh with
menu: Files-Import-GiD mesh
1- Export your triangles with the auxiliary template DXFSAP2000
menu: Files-Export-Using template (only mesh)-DXFSAP2000
2- Import again in GiD this dxf file. You will have a surface by triangle
menu: Files-Import-DXF
3- Export finally this surfaces as IGES
menu: Files-Export-IGES
