Create Aligned Linear and Ordinate Dimensions Example (VB.NET)

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 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.Forms.
' 5. Start DraftSight and open a document.
' 6. Click Start Debugging.
'
' Postconditions: 
' 1. A closed PolyLine and four Circles are constructed.
' 2. Aligned linear and ordinate Dimensions are created.
