PMI Visualization - NULL dereference while on sample STEP file

CommunityPRODUCTS:PMI Visualizationclosed6 public notes

Description

The attached STEP files cannot be imported to CAD Assistant [network address removed]. However, they do work with our NIST STEP to X3D Translator that is based on OCCT 7.6.0. https://github.com/usnistgov/STP2X3D I think I submitted these files before with another issue.

Steps to reproduce

Import the STEP files to CAD Assistant

pload XDE OCAF VISUALIZATION MODELING
ReadStep D part1.stp

vinit View1
XDisplay -dispMode 1 D
vfit

pload -DrawPluginProducts PMIVIS
PMIimport -doc D

Result:

PMI dimension import -> object '0:1:4:4' : document object does not contain semantic information. Skipping object for display.
PMI dimension import -> object '0:1:4:5' : document object does not contain semantic information. Skipping object for display.
An exception was caught [revision removed] : OSD_Exception_ACCESS_VIOLATION: ACCESS VIOLATION at address 0x0000000000000000 during 'READ' operation

Please raise trivial bug-fix adding NULL-checks
- OCC Products: branch CR32745.

http://jenkins-test-occt/view/master-CR32745-KGV/

After that it might worth to check if imported PMI entities are properly displayed / could be properly displayed within provided STEP samples.
