Build it for realPlanning terrain you will 3D-print, cast or craft? Lay out the tiles, and the Print list counts every piece, terrain group, riser block and prop. Switch to My inventory to check a design against the tiles you already own, then export the Print sheet.
Play it as a mapRunning a game on a virtual tabletop or a printed poster? Design or generate a map, decorate it, and export the Play map: a textured battle map with a 5 ft grid, ready for Roll20, Foundry or Owlbear Rodeo.
On a phone, tap where you want a tile and use the Rotate chip above the map instead of R. Your map saves automatically in this browser; use the map code in the Map tab to move it to another device.
