Hello! And welcome to the discussion groups!
Can you give a little more information on what you are looking for.
Are you talking about creating a specific window or shape of a window?
Have you looked at seek.autodesk.com for a possible component?
A little more description would allow us to assist better.
If this helped solve your issue - remember to 'accept as solution' to help other find answers!
You can't think AutoCAD and run Revit.
