calculating F.A.R
1. Identify a parcel for testing, and prepare alternative massing options for the parcel.
2. In order to calculate the Floor Area Ratio (F.A.R.) of the parcel, link the building massing using Brep component in grasshopper. Link the parcel footprint using Curve component in Grashopper.

3. Use Contour component to extract plans of the building massing. Contour distance should be set at the presumed floor-to-floor height, in this case, 4m. Use Area component, then Mass Addition component to calculate the combined floor area.
4. Use Area component to calculate the Parcel area.
5. Total Floor Area / Parcel Area = Floor Area Ratio (F.A.R.). Use Division component.
Calculating F.A.R.
6. Repeat the steps for all of the massing options, and attached Panel component to each of the outputs to display F.A.R.
