Map area

Half-width — 500 m

Map shape

Square Circle Hexagon

Click the map to add vertices — double-click to close the polygon

Import GeoJSON Polygon or FeatureCollection — holes are not supported.

Boundary smoothing — 0 iterations Chaikin corner-cutting — rounds polygon corners.

GPX file

Or click two points on the map to define a span.

Route width — 1.5 mm

Span buffer — 0.05 Fractional margin around route bounding box.

Add clip polygon Draw a polygon to clip the route map area.

Model

Size / scale

Size (mm) Scale 1:N

Longest dimension — 190 mm

Scale 1:

Filament slots 1 — terrain only 2 — + water 3 — + roads 4 — + parks (recommended) 5 — + buildings 6 — + railways 7 — + beach / sand

Terrain exaggeration — 2.0×

Features

Include buildings

Roof shapes (gabled, hipped…)

Highlight raceway

Force rivers & streams Keep waterways visible on large maps where they'd normally be too thin to print.

Skip terrain (buildings only) Outputs only building geometry — no terrain mesh.

Contour interval (metres, optional)

Elevation source Copernicus GLO-30 (default) ALOS AW3D30 — optical, better bridge decks SRTM GL1 — radar, similar to GLO-30 AW3D30 and SRTM require an OpenTopography API key — run uv run main.py --save-api-key <key> on the server.

Fine-tuning

Building exaggeration — match terrain 0 = same as terrain exaggeration

Raceway width — 1.5 mm

Waterway width — 1.0 mm

Colour depth — 1.5 mm

Water depth — 0.8 mm

Border width — 0 mm 0 = no border. Recommended: 6–8 mm.

Min building area (m²) Blank = auto. Set a value to filter small buildings.

Approx. scale: 1:3158 — smallest visible feature: ~2 m
