Draw a polygonal street

Using the Street Creation tools , you can draw polygonal streets and snap to existing streets, shapes, or guides. When you create streets and enclose an area, blocks are created automatically.

To draw a polygonal street, click the Polygonal Street Creation tool (G) to open the Tool Options window . You can also click Graph > Polygonal Street Creation in the main menu.

Click to create the first vertex and click again to place additional vertices. To finish the street, double-click or press Enter. The streets automatically snap to street segments and nodes; and shape vertices and edges. Additionally, you can snap to guides and align segments parallel and perpendicular to them. Press Shift to temporarily disable snapping. Double-click a street segment to add a vertex at that place.
