Sometimes when adding a simple linear dimension, the dimension seems to pick its own ucs, go angular, and is just wrong. What is that? I'm about to throw this thing.
Thanks
Welcome to the Autodesk forums... sorry for the trouble you are having. Can you attach a sample drawing with some of the mis-behaving dimensions?
In my experience, several things affect behavior:
1) DDUCS. If this is on and your cursor runs over any object that has surface or volume, the ucs will automatically adapt to that direction. This is easy to fix. Turn it off until you need it.
2) Dimensioning in non-ucs coordinate systems. AutoCAD doesn't like to dimension arcs in non-ucs coordinate systems. Be sure to dimension arcs in WCS.
There could be others.
