Intersection Curve: Null tag not allowed

Intersection Curve: Null tag not allowed

Intersection Curve: Null tag not allowed

(OP)
I'm getting an error that says "Null tag not allowed" whenever I try to make an intersection curve in sketch in task environment. After I click Ok on the error window, I can't rotate or pan my model without exiting the sketch in task environment first. This problem started when I re-opened my model after getting a "Internal error: memory access violation". I'm worried that my model might be corrupt, is there any way to fix this? I'm working in NX7.5 and Teamcenter 8.

RE: Intersection Curve: Null tag not allowed

Anytime you get null tag errors or memory access violations, these should be turned over to GTAC to have them look for the cause since there is very little that you can do once you start to get these.

RE: Intersection Curve: Null tag not allowed

When you get this type of errors, it might be the NX session ( not the part) that has "become corrupted" ( compare it to a tourist getting lost in a foreign city, -you just don't know the references.)
Try therefore to save and close the part, if you are worried about corrupting the part you can do a save as instead, start a new NX session and reopen the part.
Truly corrupted NX parts are extremely-extremely rare and ~99.99% of them can be repaired. If it still is spitting errors, call GTAC.
I would assume that the object that you are trying to intersect in the sketcher is the bad guy. Try run Analysis -Examine Geometry , set all options , drag a rectangle around it.
