I received a set of drawings today from a colleague, whilst this is not unusual, the drawings all had differing UCS settings, which was unusual, most of my colleagues do not touch the UCS.
Usually I reset the UCS to world and carry on. I like my modelspace to to be set to world so when I copy and paste the rotation stays the same to the screen. I tend to then rotate the UCS in viewports as and when required.
This time, typing UCS, W to reset to world UCS left me with this, a wonky UCS.
The UCS is wonky, or Y is not up the page. The square in the UCS indicates it is set to WORLD, so I was confused.
The problem was not that the view was set to the UCS but the UCS was (kind of) set to the view. I will explain. (See bottom of post for a quick explanation).
If you type VIEWTWIST, it should be set to 0 for the UCS to be the way I wanted it. I found it was set to 270!
Now I have run into another problem, the VIEWTWIST variable is readonly!
So lastly I found that typing PLAN and setting to WORLD reset everything to how I wanted.
Interestingly this problem seems to be similar to the one a while back with rotating the view in AutoCAD LT.

For a quick method of the above, if the UCS is not in the default position and it is set to world, then the view has been rotated. To rotate the view back, type PLAN, then WORLD. Or click on the arrows above viewcube in full AutoCAD.
