Get Dimension Tolerance Example (VB.NET)

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

'---------------------------------------------
' Preconditions:
' 1. Open:
'    C:\Program Files\SolidWorks Corp\SolidWorks\samples\tutorial\api\gtolwitnessline.slddrw
' 2. Open the Immediate window.
' 3. Zoom in on a dimension and click it.
' 5. Run the macro.
'
' Postconditions:
' 1. The dimension tolerance for the selected dimension
'    is set to basic.
' 2. Minimum and maximum dimension tolerances are set for the
'    the selected dimension, and their values printed to the
'    the Immediate window.
' 3. The height and scale of the font for the dimension tolerances
'    are printed to the Immediate window.
'
' NOTE: Because this part document is used elsewhere, do not
' save any changes when closing it.
