Edit position on sketch

[uwam2ie]

I'm working on NX3 an have question:
from time to time I have sketch where I'm losing the edit positioning when I'm out of the sketch task on for ex. on the MB3 dialog on the sketch. What could be the reason?
thx in ad

This may be due to the sketch and how it was positioned.
If the sketch was created and positioned using "Positioning" method within the sketch then it should be avaialable from MB3 when outside of sketcher. But... if the sketch was positioned using geometric constraints or using dimensions as constraints (but not with the sketch positioning option) it will not show postitioning options with MB3.

there are no geometric constraints, in the dependency browser there'S only datum and axis dependencies, and in the sketch I' found no constraints linked to geometrie outside the sketch...
... perhaps is there atrick to find this constraints?
