UCS Suddenly changed. cant revert back.

[Alexrose1942]

from some unknown  reason while touching a part in my assembly the UCS changed. I've tried resetting it using the "look at" and set the view as Top. no success, the UCS at the bottom still align at an angle I never choose. anyone had this issue before?

Attach the assembly and part files here - this will be an easy fix.

I am going to guess that it is your part that is skewed in the assembly.

Unground (if grounded).

Run the Ground and Root command.

Reset the assembly view.

Hi Alex,

Is this part very small (microns) or far away from origin?

Many thanks!
