The creation of supplemental drawings is common for design and construction projects, and they are typically used for addenda before the project bid or revisions after the bid. It is ideal to create a permanent copy of the supplemental drawing to create a record copy that never changes. Since the Revit model is dynamic, it can be difficult to keep that record copy within the Revit project file. While a PDF or image can be created, it is nice to have the view of the supplemental drawing be a permanent aspect of the project file. The Autodesk Subscription Advantage Pack for Revit includes the Freeze Drawings extension that is a great aid in creating supplemental drawings.
