You aren't giving us much to go on. Can you give an example? Are you seeing 0.001 mm shifts or 100 mm shifts?!
I've heard there can be rounding issues when shifting back and forth in units. The base unit in PADS Layout is
"1 mil =3810000 database units" (from padslayout_ref.pdf), Enough processing on that non-floating point number will give rounding errors.
whether this happens when changing units mm to mils and vice versa?
