I am using the following function:

////////////////////////////
SldWorks::ITessellationPtr tessel = body->IGetTessellation(0L,&faceList);
tessel->put_SurfacePlaneTolerance(0.005);
////////////////////////////

No matter what value I use to set I don't see the difference in theface count? What is going on?

Also I would like to know the range of SurfacePlaneTolerance.Please help. Thanks in advance.SolidworksApi macros
