I did my bachelor's degree in Mechanical and Automation Engineering. I have 12 years of combined experience in building services and power industry. Currently, I am working as a Revit MEP draftsperson with a mechanical contractor. I have personal interest in developing Revit Addins which can be very helpful in day to day work. I would like to share my first addin ' Revision Extractor ' and would appreciate valuable feedback from Revit users.
