Designing citys with 6 kinds of blocks (commerce, park, hospital, high rise residential, terrace residential, school, no block = parking). Use the maker pen to move and clone blocks. For best results use snapping (uncheck world coordinates snapping) with 1m grid and 90 degrees rotational snapping. Inspired by the CityBlocks project by Lee Kent, see: https://dmf-lab.co.uk/blog/category/projects/cityblocks/ .
