Convert tolerances from inch to mm

[horst]

I converted a drawing from inch to mm by scaling by 25.4 as the AutoCad
help suggested.
In this way all dimensions have been properly converted.
But the tolerances didn't change!
Is there a way to convert the tolerances too?
Thanks for your help

Have you tried changing the dimension style setting and then updating all
dimensions?

Sorry, I don't understand what you mean.
The domension style applies to both the standard size AND the tolerance.
What I wanted to say is that when I have an object with a size 1" +/-
0.1 after the conversion from inch to mm I get a size of 25.4 +/- 0.1
instead of 25.4 +/-2.54
There should be somewhere IMHO a switch which allows to change or not to
change the tolerances after a scaling operation.

I don't use them in my work, but my understanding is that the tolerance in a
dimension style is specified in the dimension style. Depending on your
version this would be tucked somewhere in the DIMSTYLE dialogues. Just
because you scaled the drawing doesn't mean that the dimstyle has been
adjusted.

Go in there and you will probably find that the tolerance is still set to
..01. Set it to 2.54. If all the dimensions don't automatically update when
you get back to the drawing, select all those still reading +/- .01 and
issue the DIM>UPDATE command. That should do it.

After scaling the drawing you may want to examine/adjust your unit
precision, as this may adversely effect the display of your tolerances if it
is bigger.

I don't specify tolerances in DIMSTYLE as they all differ from each other.
I specify tolerances for each quote.
It is true that a possible automatic conversion would give me 25.4 +/-
2.54 instead of 25.4 +/- 2.50 (which is more common), but it would be in
any case better than 25.4 +/- 0.1 as today.
It is also true that there should be a switch to prevent a normal
scaling to show from 10 +/- 0.1 to 12 +/- 0.12 when the tolerance should
remain the same as before.
