When I work with Revit Structure 2015 to make rebar and area reinforcement, i have an issues with rebar number. In my country, each company has a difference way to show rebar number. Example: 1,2,3,1a,2a,3a...I think that Enable rebar number with editable-user is a good method, Please give me some advices, thanks for your concern. (1 attached image)
