Can Salome be used to convert a mesh , STL to a surface , IGES file?

cheers, Steve

Hello Steve

Yes, it's easy. See the script

St.Michael

Thanks, St.

if i get this error does it mean the stl file has to many faces?

Then you can use pure OpenCASCADE, namely DRAWEXE test harness, for this conversion (using the attached script). To run DRAWEXE  you can replace in run_salome.bat "START runSalome" by "START DRAWEXE". Launch run_salome.bat; when a prompt (Draw[1]> appears in the opened window, type "source path_to/stl_2_iges.tcl.
That's all.
