NX6 - Angled plane is fixed after creating the plane

[supahonkey]

Ladies and Gentlemen,

I have NX6 and I regularly design CMM probe bars that have compound angled surfaces. I create a plane and rotate it about an axis. I then rotate another plane about an axis that is aligned to the first plane.

Occasionally I run into an issue where I cannot go back and edit the second angle once it has been created. I am able to edit the first angled plane, but not the second. Double clicking on the plane brings up the Datum Plane dialogue box, where it tells me the plane is fixed.

Does anyone have any idea why this happens? Sometimes I don't have the issue and I can't find a pattern as to why this happens.

The red plane is the first angle. The green angle is the second angle.

Thanks,
Brenton

I take it back, I now cannot edit the first angle.

Wow, I figured it out just now after months of intermittently have this problem. I didn't have the "Associative" box checked for the plane. Everything works just fine now.
