# Get DimensionStyle Names and Options Example (VB.NET)

This example shows how to get the names and options of the DimensionStyles in a document and how to export the current view of the drawing to a PNG file.

'-------------------------------------------------------------
' Preconditions:
' 1. Create a VB.NET Windows console project.
' 2. Copy and paste this project into the VB.NET IDE.
' 3. Add a reference to
' install_dir\APISDK\tlb\DraftSight.Interop.dsAutomation.dllb.
' 4. Open the Immediate window.
' 5. Start DraftSight.
' 6. Click Start Debugging.
'
' Postconditions:
' 1. Specified document is opened.
' 2. The document's DimensionStyle names and options are printed to
' the Immediate window.
' 3. The current view of the drawing is exported to a PNG file.
' 4. To verify step 3, open
' C:\ProgramData\Dassault Systemes\DraftSight\Examples\B-44563.PNG
' using an application like Microsoft Paint.
