Rotate and Copy Entities Example (VB.NET)

This example shows how to rotate and copy selected entities.

' Preconditions:
' 1. Create a VB.NET Windows console project.
' 2. Copy and paste this example into the VB.NET 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.
