This example shows how to construct Ellipses and elliptical Arcs.
'-------------------------------------------------------------- ' 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. Start DraftSight and open a document. ' 5. Start debugging the project. ' ' Postconditions: A message box pops up when an Ellipse or ' elliptical Arc is inserted in the drawing document. '----------------------------------------------------------------
