[cgma-dev] Large OCC subtraction time

[Rajeev Jain]

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.

RGG o/p:

ACIS:

Normal Termination.
Geometry file: 7.sat saved.

Elapsed wall clock time: 8 seconds or 0.133333 mins


OCC: 

Exported: 327 OCC Bodies to 7.stp

 Normal Termination.

Schemes file created: 7.template.jou
Cubit journal file created: 7.jou

Elapsed wall clock time: 3173 seconds or 52.8833 mins

The geometry files can be found at 
/homes/jain/MeshKit-all/trunk/rgg/test/geometry_parallel_meshing/7.stp and 7.sat
