Autodimension Selected Drawing View Example (C#)

This example shows how to autodimension a selected drawing view.

//-----------------------------------------------------------------
// Preconditions: Verify that the specified drawing document to
// open exists.
//
// Postconditions:
// 1. Opens the specified drawing document.
// 2. Activates Drawing View1.
// 3. Selects a vertex.
// 4. Autodimensions the drawing view based on the
//    selected vertex.
// 5. Examine the drawing.
//
// NOTE: Because the drawing is used elsewhere, do not save changes.
