Get Dimension Tolerance Example (VB.NET)

This example shows how to get and set dimension tolerance values and options.

' Preconditions:
' 1. Open public_documents\tutorial\api\box.slddrw.
' 2. Open the Immediate window.
' 3. Zoom in on the diameter dimension and click it.
' Postconditions:
' 1. Sets the dimension tolerance type to fit with tolerance.
' 2. Sets the dimension fit tolerance type to transitional.
' 3. Gets the minimum and maximum dimension tolerances for the
'    selected dimension and whether the values are valid.
' 4. Gets the height and scale of the font of the dimension
'    tolerances.
' 5. Sets the dimension fit tolerance font to be the same 
'    size as the dimension tolerance font.
' 6. Gets the height and scale of the font of the dimension fit 
'    tolerance.
' 7. Examine the Immediate window and drawing sheet.
' NOTE: Because this drawing is used elsewhere, do not save changes.
