display mm dim in imperial drw

[saspinall]

We use imperial dimensions for the vast majority of our modelling. However on some ocassions we use metric especially when using holes or revolve cuts. On the drawing, I know that I can overwrite an added dimension using the @O command in dim text but that is only for nominal dims. Is there anyway to add upper and lower limits or +/- values as metric values in an added dim or a way of overwriting driven dims, or is it simply a case of using text note for the tolerance values.


Thanks, Stu

Have you tried dual dimensioning?


Modify these in your drawing setup:
dual_dimensioning (Multiple options to try)
dual_secondary_units mm

Thanks for the reply, Anders. However this will turn them on for all dimensions and I only want to show 1 as being in metric with all others in imperial. Like I said, I've managed to do it by simply adding a new dimension and then over-writing it, but I have to add the tolerances as a note.

Then this might be what you are looking for (or is this what you mean with a note?):


{0O}{1:50}{2+ 1 @#}{3- -5 @#}


This will display as 50 +1 -5 (but as upper- and lower-case)

Thanks Anders although I didn't know how to get the note to be upper and lower limits, (I added it as a 2 line note) but as the saying goes :-


"You learn something new every day!".


This solves the problem for the moment although what I would really like to do would be to dual dimension just the single dim, you dont know if this is possible or not do you ? then it would be a driven dim in case of future mods.
