<DIV> </DIV>
<DIV>Thank you for providing the testcase. OCC did have a reputation of getting much slower with larger models and more operations. I'll have a look on Monday to see if there's anything I can do on cgm side that can speed it up.</DIV>

<DIV>Have a nice weekend!</DIV>

<DIV style="FONT-SIZE: 10pt; COLOR: #000000; FONT-FAMILY: arial, helvetica, sans-serif">When subtracting 325 pins from a block, OCC takes a lot more time than the corresponding ACIS model. I'm attaching the assygen .inp that can be run as MeshKit/rgg>assygen 7. This file is for OCC version of MeshKit. For ACIS change the geometry engine to ACIS in the .inp file and run ACIS version.<BR><BR>RGG o/p:<BR><BR>ACIS:<BR><BR>Normal Termination.<BR>Geometry file: 7.sat saved.<BR>Schemes file created: 7.template.jou<BR>Cubit journal file created: 7.jou<BR>Ending at : Fri Feb 25 15:10:31 2011<BR>Elapsed wall clock time: 8 seconds or <SPAN style="FONT-WEIGHT: bold">0.133333 mins</SPAN><BR><BR>
