Hi, I work for a company in bespoke design. We are in the process of modelling some of our products in 3d using families. I am looking at ways of revising our design in both model and sheets. Ideally we would like to have one revit drawing file that we can revise as many times as required. Is there a way we could potentially revise an entire design whilst keeping previous revisions in model space? I have looked at using the design options tool and also the use of revision clouds and tags. Which would be the best way to go about it? Any input would be greatly appreciated.
