Create Aligned Linear and Ordinate Dimensions Example (VBA)

This example shows how to create aligned linear and ordinate Dimensions for a closed PolyLine and Circles. A Leader and a geometric tolerance are also created.

'-------------------------------------------------------------
' 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:
'    install_dir\bin\dsAutomation.dll
' 4. Start DraftSight and open a document.
' 5. Run the macro.
'
' Postconditions:
' 1. A closed PolyLine and four Circles are constructed.
' 2. Aligned linear and ordinate Dimensions are created.
