Lilac is the first urban design application with the urban transect, public space, vistas and

pedestrian scale baked in.

Quickly produce regulating plans for greenfield and brownfield sites Import simple static backgrounds

[PRO] Start with detailed site terrain

[PRO] GIS import

Place existing buildings and natural features - and planned civic buildings - onto the site By default these are placed as simple blocks: a lake flat, a tree tall and thin, a complicated building as a series of blocks.

[PRO] Import complicated existing or civic buildings

Use default transect settings to generate draft 3D scenes Choose from built in North American Traditional or Modernist transect parameters and facades

[PRO] Calibrate transects to your own site and tradition

Note passive warnings such as No four-way stops allowed (remove restriction in [PRO])

3 transects per 5 minute walk

Transect violation (adjacent)

Block length Terminating vistas onto civic buildings

[PRO] Export into Sketchup, ESRI formats
