Use this when you want to subtract one geometry from another within a flow, for example removing a courtyard or road reserve from a site polygon.
Category: Geometric Operations

How to
Start with a geometry you want to subtract from
You can use read feature to get the original flow geometry, or the results of any other geometric operation.
Feed in the geometry you want to subtract.
This can be Lists of multiple geometries!
The result is the original geometry with the area of the “B” geometries removed.
Use case
Create a parking solver that generates parking bays around overlapping buildings.
