Gridly — Road & Track Tools

Straighter streets, tidier tracks, fewer "close enough" moments. Turn Gridly On in the road or track toolbar for grid/angle snapping, curves, height controls and crossings. Click to start, click to build, right-click to stop; Esc closes. Turn Gridly Off for the normal builder. Settings, minus the homework: - Road / Track defaults: choose starting grid spacing, angle, elevation, height snap and crossings separately. Grid spacing starts at 20 m. Tweak grid and angle freely. Keep elevation at 0 and height snap Off unless you're planning matching heights, bridges or tunnels. Toolbar choices still win. - Extra grid choices: add up to three spacings for both builders, or leave Off. Range: 5–500 m; steps grow from 5 to 10 to 20 m. Pick your extras in the toolbar. - Node snap distance: 4 m is a good starting point. Raise it for easier connections; lower it if nearby nodes feel a bit too clingy. - Grid display radius: 20 steps by default. Lower it for less clutter and drawing work; raise it for a bigger planning view. Snapping stays the same. - Terrain smoothing: keep 60 m to start. Raise it for gentler hills; lower it to follow the ground more closely. Only affects Terrain height mode. - Crossings: leave Join for junctions and road–rail crossings. Off prevents joining; it doesn't magically make routes pass through each other. Crossings need room. Track switches: use the normal builder. Built on Parallelism by Imsvale (MIT).
