Get Dimension Tolerance Example (VBA)

This example shows how to get dimension tolerance minimum and maximum values.

'--------------------------------------------------------------------
' Preconditions:
' 1. Open install_dir\samples\tutorial\api\box.slddrw.
' 2. Open the Immediate window.
' 3. Zoom in on the diameter dimension and click it.
'
' Postconditions:
' 1. Changes Tolerance Type to Fit with tolerance.
' 2. Gets the minimum and maximum dimension tolerances for the
'    selected dimension and whether the values are valid.
' 3. Gets the height and scale of the font for the dimension
'    tolerances.
' 4. Examine the Immediate window and drawing sheet.
'
' NOTE: Because this drawing is used elsewhere, do not save changes.
