New Revision: 5178

Modified:
   cgm/trunk/itaps/iGeom.h
   cgm/trunk/itaps/iGeom_CGMA.cc
Log:
Added a iGeom_getEntClosestPtTrimmed interface to call closest_point_trimmed function for surfaces. This is to avoid projecting point onto void space of a surface. Per Shengyong's request.

Modified: cgm/trunk/itaps/iGeom.h
