It seems that in cubit case, we do a conversion to sat format, first.<br><br>ITAPS GEOMETRY INTERFACE TEST PROGRAM:<br><br> gLoad: Reading STEP/IGES file '/home/iulian/tmp/test_lorenzo/cduct.igs'...<br>Model conversion succeeded: /tmp/CBT.Hoo5yc.sat<br>Read 6 ACIS Entities from the input file<br><br><br>Constructed 6 Volumes: 1 to 6<br>Model contents: <br>vertices: 24<br>edges: 24<br>faces: 6<br>regions: 6<br>vertex index 0 : 0 0 0<br>vertex index 1 : 0 1 0<br>vertex index 2 : 10.5 15 0<br>vertex index 3 : 11.5 15 0<br>...<br><br> testgeom_occ cduct.igs <br>Geometry engine set to: OpenCascade 6.3<br><br><br>ITAPS GEOMETRY INTERFACE TEST PROGRAM:<br><br> gLoad: Total number of loaded entities : 78.<br><br>Constructed 6 Volumes: 1 to 6<br>Model contents: <br>vertices: 24<br>edges: 24<br>faces: 6<br>regions: 6<br>vertex index 0 : 0 0 0<br>vertex index 1 : 0 1000 0<br>vertex index 2 : 10500 15000 0<br>vertex index 3 : 11500 15000 0<br>...<br><br><br><br>Can you please tell me what we should do to get similar results ?<br><br>Thanks,<br>Iulian<br><br></div></body></html>
