Tolerances on Dimensions

#1
I have a couple questions regarding tolerances on dimensions.

Do you normally use the tolerance tab of the dimension settings dialog?

Do you append them yourself as text?

Do you create the dimension and then select the dimension, hit properties, and add the tolerance after the <> in the properties window? (I seen someone suggest this method with ACAD, don't know what version they were using though) This would probably be a good way to do it for a dimension like 340 H7 (We work in all millimeters)

Do you create a different style for each amount of tolerance you wish to apply to a dimension. Like a style for +.5/-0 and another for +.05/-0, etc..

Or do you use overrides?

If you do tolerance the way discussed here, doesn't this constantly change the style?

Thanks for any input,
Bryan
