How to do areas and ratios on many sites simultaneously
Use the Precinct app to organize the geometry you added to drawing layers into side-by-side Scenarios to make metric comparisons.
Set up your project to work with the Precinct app:
Precinct works based on comparing geometry drawn on separate drawing layers.
Create layers per scenario you plan to compare:
One for geometry, like buildings, roads, parking, and landscape
Create multiple geometry layers if you want to compare geometry sitting in the same parcel (IE - multiple building configurations for the same site)
You only need a single geometry layer if you are comparing geometry sitting on multiple disconnected parcels
One for Polygons. The polygons should outline the parcels you wish to compare. This is how Precinct will understand to calculate your coverage metrics from.
Create a single parcel outline if you are only using one site
Create multiple if you are comparing multiple sites.
Example of Disconnected Parcels:
Example of a single parcel:
Add the Lot Number (lotNumber) from Properties to all of the parcel polygons to wish to analyze.
Enter a value. This could be as simple as “Option 1, Option 2” or could reflect real-world municipality lot numbers.
💡 Note: Precinct will count geometry fully contained within the polygon you set with the Lot # property. If you move geometry from one parcel to another, precinct will recognize that geometry in the new parcel only.
Add the App
Navigate to the Precinct app in the right hand tool palette by clicking on the Precinct tab.
Create Scenarios
Click “Add new Scenario” to get started.
Select the reporting metric: GBA. GFA, or NRA
Select layers.
The geometry layer must contain your building and built form geometries, and the lots layer must contain 2D polygons, each representing a lot. The lots must have the Lot# property applied.
Once you select the layers you wish to analyze, data will populate. Repeat for each of your layers to see multiple options side-by-side.
