Create shapes from graph networks

Graph Networks can automatically create shapes, such as lots or street shapes.

To enable or disable shape creation, use the shapeCreation parameter at the block, street or node parameters in the inspector. By default, shape creation is enabled.

Input: A graph network. Output: Lots and street shapes.

Shape creation parameters

Lots and street shapes can be controlled through the corresponding parameter panel in the Inspector.

• Blocks create lots, see Block Parameters
• Segments create street shapes, see Street Parameters
• Nodes create intersection shapes, see Intersection Parameters
• The default start rules for the shapes generated by nodes and segments are specified by their shape types, see Street and Crossing Shapes

Alternatively, the Street Tool can be used to edit street widths or setup curve handles.

Note:

For each loop in the graph network, a block is automatically created, see Graphs for details.

Object attribute inheritance

• Lots inherit the attributes of the block
• Street Shapes inherit the attributes of the segment
• Intersection shapes inherit the attributes of the node

Note:

The italic font indicates inherited attributes in the Inspector:

Left: A standard attribute of a graph segment.

Right: The (same) inherited attribute of the corresponding street shape.

UV coordinates

UV coordinates are generated for each shape. They can be used for UV Splits and texturing. For details of the UV coordinates, see Street and Intersection Shape UVs.
