Starting the 3D view…
Height-map relief
Move the map, then build the land in view. The base and the land are one solid piece. Water, parks and roads are part of that same model.
Up to 4 colours in one print. Parks, forests, beaches, golf and paths use the land colour. Trails, rail and water share colour 4. Set colour 4 to red when the trails matter more than the water.
Hiking trails follow the land in red. Water mains and power lines are not in the map data. Concrete is off unless you turn it on. One print piece is 320 × 320 mm and 300 mm tall. Anything larger is split into another piece in the same file.
Hamilton is on the map. Build the view when you are ready.
