And this is undesired.
It is as if running the UCS command to alter the UCS automatically results in the firing of the "PLAN" command to make my screen view the drawing on the XY plane.
Before, my normal behavior was to change the UCS, and then, -if desired-, enter PLAN;Current; to set my view to that new XY plane.
However, now it's doing that automatically, and I sincerely do not want it to 9 times out of 10. I'm viewing my model in a generally isometric orientation, and when changing the UCS via command line, it automatically sets it to a plan view... so I have to switch back.
I cannot find what is causing this in help or Google. Any help?
