The Internal Drive Network supports three types of Circulation patterns that determine the orientation and relationship of drives to buildings within a region or site: Internal, Perimeter, and External.
Most housing typologies and presets support multiple circulation types, enabling users to control how the internal drive network is structured and how buildings relate to circulation within the site.
1. Internal Circulation
Internal Circulation centralizes the flow of movement within the interior of the site.
Buildings are positioned along these internal drives and typically align with the boundaries of the region and/or site. This layout emphasizes inward-facing organization, creating a cohesive internal network that defines the site’s internal structure.
2. Perimeter Circulation
Perimeter Circulation places the primary drives along the outer edge of the region or site.
In this configuration, buildings are centralized within the bounds of the perimeter network. This layout emphasizes external access and can create clear, defined site edges suitable for contained developments.
3. External Circulation
External Circulation establishes multiple rows of internal drives that organize buildings within the region or site. These internal drives extend outward and terminate at the site boundary, allowing to represent potential connections to existing external infrastructure. This approach provides flexibility for integration with surrounding road networks and supports phased or modular site expansion.
4. Organic Circulation (available in the Subdivision typology)
Organic Circulation establishes a curved network of drives the lead to cul-de-sacs or connected drives internal of the preset region. Under the Drive Network layer in the Nav Tree in the property panel, branching solves can be adjusted by selecting the "change" button (reset the branching as required), branching connectedness can be adjusted with the slider, the turn radius can be defined, and the cul-de-sac radius can be defined.
