This example shows how to construct an Arc.
'-------------------------------------------------------------- ' Preconditions: ' 1. Create a VBA macro in a software product in which VBA is ' embedded. ' 2. Copy and paste this example into the Visual Basic IDE. ' 3. Add a reference to the DraftSight type library, ' install_dir\bin\dsAutomation.dll. ' 4. Start DraftSight and open a document. ' 5. Run the macro. ' ' Postconditions: A message box pops up when an Arc is ' constructed in the drawing document. '---------------------------------------------------------------- Option Explicit
