Rotate and Copy Entities Example (C#)

This example shows how to rotate and copy selected entities.

//--------------------------------------------------------------
// 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 new document.
// 6. Construct multiple entities (e.g., circle, rectangle, 2D PolyLine,
//    etc.).
// 7. Start debugging the project.
//
// Postconditions:
// 1. When the prompt appears in the DraftSight command window,
//    select the entities to rotate and press the Enter key. The
//    selected entities are rotated.
// 2. Execution stops so that you can examine the drawing to
//    verify that the selected entities were rotated. Click the
//    Continue button in the IDE to continue.
// 3. The selected entities are copied.
