Hi,

>> every time when i worked on AutoCAD, my ucs will change

The UCS can only change by itself when "dynamic UCS" is active, try to turn it off (using UCSDETECT or <F6> ... >>>details<<<)

(or you do have 3rd party apps installed, which might use UCS in it's application functionality)

This thread had a similar discussion:

See if any of the info there helps.

thanks a lot, i guess currently the best way to fix this is to use custom ucs

If the complexity of the drawing is fairly low (just geometry in ModelSpace), a copy and paste into a new drawing is probably the most straight forward method to get the Orthographic Views re-coordinated with the WCS.

If not, follow the suggestion about creating new named UCSs.

In reference to some of the posts in that other thread; do you often use the PressPull command?

Indeed you do have an extreme level of detail going on there. Try to make note if you run into the Orthographic View UCS problem again. I suspect the problem results from UNDOing back through a PressPull command. I was able to capture one occurrence of the problem here:

It is not an easy situation to replicate, however.

I have found that when selecting presspull from the 3d Modeling Workspace ribbon, the UCS doesn't change. If CTRL+SHIFT+E is used to trigger presspull, then it does cause the anomalous UCS.
