I haven't checked online for bug re****ts, but this reminds me of the
"normal" screwiness that happens when PTC has changed the default
operation
of certain options or has added or removed options which before governed
certain behaiors. However, limits getting ****fted up by .002 is very odd.
The only thing I know of that can generally do something like that is in
the
'Edit>Setup' menu, a function called Dim Bound which can ****ft the
tolerance
to the high or low end of the limits, but not ****ft the limits themselves.
At the same time, I've recently seen screwy stuff with dimensions and
tolerances, just because the default tolerance standard got somehow
switched
from ANSI to ISO, truncating zeros from all dimensions. In other cases,
dimensions got rounded to two decimals. But when the dimensions were
highlighted in the drawing and 'Format>Decimal Places' was applied to make
them 3 places, a truncated third place appeared. So, they hadn't been
rounded, just truncated to 2 places and didn't require regen as they would
if you changed them with Properties. Actually, some of those might have
been
soft dims. Yet others, when shown, had 4 places. Much of this I attribute
to
switching revs (WF2 to 3) and to carelessness with a config.pro file.
