default tolerance for boss height

All,

I have a boss in a part model, and want to check its height.

I select Smart Dimension, then select the top face of the boss and its base surface.

I get a dimension label with the height and +/- .020 tolerance.

If I go to Options>Document Properties>DimXprt>Size Dimension,  there are several items with a +/- .020 default.

However, I changed all of them and it still puts the +/- .020 with the dimension.

Not terribly important, as I can set whatever tolerance I want in the drawing, but annoying.

Anyone know where that setting is?

Thanx

Don
