I am starting a Beta group to design and error check a library of Revit doors and windows. The concept is to create a complete set of doors and windows that contain all options and details needed for the residential market. Ultimately this library would be sold to users. If you are interested in being part of the beta group and getting a bunch of free families and support please click on the attached link and fill out the survey. I will email a link to the files so you can start using them.
