Get Dimension Tolerance Example (C#)

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.
// 4. 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 tolerance
//    are printed to the Immediate window.
//
// NOTE: Because this part document is used elsewhere, do not
// save any changes when closing it.
