While trying to load any STEP or IGES file in Inventor 2009, Inventor hangs and doesn't respond.
This issue is caused by a Microsoft defect. We need to generate the translation report while importing IGES/STEP/Parasolid files, but this defect blocks the report creation.
In such cases, try the following workaround after installing Service Pack 2 for Inventor 2009.
1.Right click on My Computer and choose Properties.
2.In Windows XP, Click “Advanced”.
3.In Windows Vista, Click "Advanced system settings".
4.Then Click the Environment Variables, a dialog pops up.
You can add the variable as following.
Variable name : TRANS_REPORT_OPTION
Variable value : 1
With Inventor 2009, TRANS_REPORT_OPTION can be any value if only it is not empty (Works with 1 & 2).
With Inventor 2010, TRANS_REPORT_OPTION should be 2.
5. Restart Inventor.
6. Try to import a STEP or IGES file into Inventor.
