Units smaller than 1/16"

Is it possible to get Visio to recognize a dimension in scale smaller than
1/16"? I'm trying to produce a drawing that shows dimensions like 17/32, but
the program only rounds out the number down to 1/16.

While I know I can override the text and write in my own numbers, I'm using
the program to help me think through some dimensioning issues. I'd like to be
able to have the dimensioning tools help me out.

Nevermind. I found what I needed to do by poking around.

After dragging the vertical dimension shape to the page and selecting "Show
ShapeSheet" in the 'Window' menu, I found the 'User-defined Cells' table. In
the 'User .InchPrec' column, '16' is the default unit of precision. I was
able to change '16' to '32'.

To test if the change worked, I adjusted the vertical dimension shape and
was able to see the text reflect the size change.

Because I feel this worked only for that specific shape, I'm going to poke
around some more to see if I can adjust the dimensions globally. If anyone
has done this, I'd appreciate any response.
