Get Dimension Tolerance Example (C#)

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.
