Summary

0002821: IGES file not impored correctly

Description

Bug from Open CASCADE community
Bug has been registered by Narasimha

http://www.opencascade.org/forumorg/bug.php?bug_id=132 [^]

The attached file "mixer_solid.igs" did not imported properly. It was missing
the cylindrical face connecting to the two pipes.

I have tried on both CVS version of OCAS and OCAS 5.0 standard installation.

Both failed to bring this surface.
This File is exported from PATRAN

Additional information
and documentation updates

Documentation remark, added by pdn 2003-10-20 09:36:50:

Improvements:
The reading of weights in the frame of the IGES translation was impeoved. Some
systems write uninitialized values instead of zeros exporting of the polynomial
BSplines. The protection on reading of "memoty junk" was implemented.
Modified entities:
IGESGeom_ToolBSplineSurface.cxx
Protection on zero and negative values of weights.

liriges.c
Protection on reading real values between 0 and 1 if decimal point is missed by
sending system
