Use subdivide lots to divide a larger polygon into smaller parcels or lots by specifying the target frontage or area. Add building envelopes to the created lots.
Subdivide is a complex transform. It is typically used for creating subdivisions and townhomes.
Inputs

Site | S | Object | List | The site output |
Envelope | E | Object | List | The envelope output |
How to
Add the subdivide lots node and subdivide lots transform
Click “edit defaults” to set the starting values
You can also feed in a Line to the Spine connector (S) to define the manual spine
Subdivide Lots settings
The subdivide lots transform automatically adds all of the settings you need for the node to your properties palette. Adjust settings to change the flow result.
Solve for Frontage or Area
Frontage: solves for a target length of the front of the parcel
Area: Solves for a target area of the parcel (not the envelope)
Toggle splitting on the spine (divide down the center)
Flip the direction the algorithm solves from
Solve spine automatically or manually edit
Automatic divides the shape evenly down the horizontal center
Manual allows you to edit the start and end point of the spine, and add corners.
Targets
Set inner and end area targets: The algorithm will target these areas with a margin of error, and lots may be slightly larger or smaller
Set inner and end frontages: The algorithm wall target these areas with a margin of error, and lots may be slightly larger or smaller
Absolute Minimums
Prevent the algorithm from creating lots smaller than a size you select
Set minimum areas and frontages
Envelopes
Toggle generation of building envelopes
Adjust setbacks for front, rear, and sides
The outputs of subdivide are site and envelopes.
The site output is the outline of each parcel in an array.
The envelope output applies the setbacks to output an array of smaller outlines.
Inner versus End
The inner versus end frontage or area options allow differently sized lots within the same solve.
The spine location controls inner versus end lots. Move the spine end node away from the outer edge of the polygon to add end condition lots.
Use Cases
Single Family Greenfield
Townhomes (attached)
Set the side offset to 0 and un-toggle “corner frontage” to create townhomes
