Create Rectangular Viewport Example (C#)

This example shows how to create a rectangular Viewport.

//--------------------------------------------------------------
// Preconditions:
// 1. Create a C# Windows console project.
// 2. Copy and paste this example into the C# IDE.
// 3. Add a reference to:
//    install_dir\APISDK\tlb\DraftSight.Interop.dsAutomation.dll
// 4. Add a reference to System.
// 5. Start DraftSight.
// 6. Open the Immediate window.
// 7. Press F5 to debug the project.
//
// Postconditions: 
// 1. A Viewport is created on Sheet2.
// 2. Examine the drawing and output printed
//    to the Immediate window.
