Construct 2D PolyLine Example (C#)
This example shows how to construct a 2D PolyLine in a drawing document.
//--------------------------------------------------------------
// 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. Start debugging the project.
//
// Postconditions: A message box pops up when a 2D PolyLine is
// inserted in the drawing document.
