Create and Change Trace Example (VBA)

This example shows how to create a Trace and change its vertex coordinates and thickness.

'--------------------------------------------------------------
' Preconditions:
' 1. Create a VBA macro in a software product in which VBA is
'    embedded.
' 2. Copy and paste this code into the Visual Basic IDE.
' 3. Add a reference to the DraftSight type library,
'    install_dir\bin\dsAutomation.dll.
' 4. Start DraftSight.
' 5. Press F5.
'
' Postconditions:
' 1. Connects to DraftSight.
' 2. Gets the active document.
' 3. Creates a Trace.
' 4. Sets the vertex coordinates of the Trace.
' 5. Sets the thickness of the Trace.
' 6. Gets the vertex coordinates of the Trace.
'    Click OK to close each message box.
' 7. Gets the thickness of the Trace.
'    Click OK to close the message box.
