Create Polygon Face Mesh Example (C#)

//-------------------------------------------------------------
// 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 references to System and System.Windows.Forms.
// 5. Start DraftSight and open a document.
// 6. Open the Immediate window.
// 7. Click Start Debugging.
//
// Postconditions:
// 1. A Polygon face mesh is created and zoomed to fit.
// 2. All Polygon face mesh parameters are printed to the Immediate
//    window.
