Draw a box around a dim? (theoretically exact)

[plusfours]

The ISO Handbook suggests that for defining the position of holes on a plate, one way is to use postional tolerance (circle with centre mark) for the centre of each circle and a theoretically exact dimension. This is signified by a rectangular box round the dim, but I can't see how to do this automatically. Anyone met this and succeeded?

Cheers,

In the properties box that comes up when you dimension, it is in the pull down list for tolerances- select "basic."

Thanks,

That has cleared it up!
