You get a file for a printable N scale (1:160) sheet of Spanish tile roofing and a file for edge pieces. The file can be rescaled to any scale including HO. Also included is a Sketchup file. The Sketchup file is water tight, print ready, and can be edited and rescaled. Note that the scaling in the Sketchup file is ten times larger than the scale size due to Sketchup performing poorly at tiny scales. The N scale sheet is sized to fit most resin printers.
