Self intersecting section error while running *.cs file

[nithinv]

Hi All,

I am running a journal file (*.cs) which is intended to create a standard part I use in my assembly. I got this file from the catalog software. This particular file runs smoothly for sometime but suddenly it stops showing an error. Screenshot of error message attached.

I don't know NX journal but as far as I understand the issue is extruding a section which has self intersecting curves. Could anybody help me to avoid this error?

Thanks in advance.

NV.

A couple of quick ideas:
[ul]
[li]edit the code so that it does not create a self-intersecting section[/li]
[li]edit the code so that it uses the "stop at intersection" option[/li]
[/ul]

Dear Cowski,

Thanks. Below is the portion of *.cs file were error happened. Underlined line shows error. How to edit this so that extrude will either "select region boundary curves" or "stop at intersection"? I also have uploaded the *.cs file for your reference.

Thanks in advance.
