Align Drawing Views Example (C#)

This example shows how to align drawing views.

//-------------------------------------------------------------
// Preconditions:
// 1. Verify that the specified drawing document to open exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified drawing.
// 2. Horizontally aligns Drawing View6 with
//    the center of Drawing View3.
// 3. Examine the drawing and Immediate window.
//
// NOTE: Because the drawing is used elsewhere, do not
// save changes.
