# Construct InfiniteLine Example (VBA)

This example shows how to construct an InfiniteLine.

    '--------------------------------------------------------------
    ' 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 drawing document.
    ' 5. Run the macro.
    '
    ' Postconditions: A message box pops up when an InfiniteLine is
    ' constructed in the drawing document.
