The question I asked the other day regarding not being able to set the
dimension unit precision to three places turns out to only happen in one
particular drawing file. I converted the drawing from R 12 MAC to R 13
c4a NT 4.0, and then copied and pasted the drawing in the same folder so
that I could create a similiar drawing. In the other drawings I have
converted, the units precision can be set correctly. Could this file
possibly get corrupted in the copy and paste functions of NT 4.0? I
don't know for sure but I've tried everything suggested and nothing
works for this drawing.
