Revit Massing Diagrams with Floor Area Ratio Calculations

Revit has great tools for graphically representing massing strategies but it goes beyond that by offering parametric data for those masses, which can be used to calculate and constantly update Floor Area Ratios (F.A.R.).
1:05 Using the Floor tool to create the masses
2:50 Floor type for the site/property
3:15 Sidewalk & Street floor types
3:45 Labeling/Tagging the masses
5:20 Loading the floor tag
6:15 Modifying the floor tag so it displays area
8:40 Adding the Site Area parameter
10:40 Creating the Schedule
11:25 Adding the custom F.A.R. calculation field
13:15 Filtering the schedule to remove unnecessary floors
13:48 Sorting the schedule by type
14:24 Formatting the schedule
15:10 Rounding the F.A.R. calculation result
16:15 Final calculation result
16:35 Modifying the floor masses to test parameters and see updated F.A.R.
17:25 Refining the mass graphics using the linework tool
