I am trying to do some trackway layouts for an event using the symbols on the attached picture (Black = full panel, Green = Half panel lengthways, Red= Half panel widthways, and Purple = quarter panel). I want to be able to set loci up on these such that the corners of the shapes will always snap to the correct locus on an adjacent shape, hence making it quicker to cover a large area with symbols and still be able to use the data download to count up how many of each symbol there are. Currently I am having to manually set up an area and copy and paste to fill in. Ideally I would like to find a way that I can draw any shape and then populate with combinations of the symbols to fill the area. Can't use the Tile function for the pattern as I need to be able to count individual symbols.
