Now that uploading larger images here (several times larger than you can on FB) is possible, and with equal ease, I mainly visit the FB Group to help new users and test the water with new ideas.

When I post a map I post in both places, though I usually run better WIP threads right here on the forum where I can always find my stuff. I don't waste time trying to find and continue old FB posts, so the information there is bitty and all over the place compared to here.

Interesting but otherwise useless fact: There may be a discrepancy between what Americans call mold and what Brits call mould. To me, a mould is never green, being more like a slime mould or fungus. Anything green is algae, lichen or moss.

Ralf generates a grid and index of place names next to the map in this video here.

This link is direct to the point where he starts that process, though if you have time to sit and watch from the beginning it is a nice overall learning experience.

This method will give you a great visual grid, but doesn't really sort out a snapping grid. I am assuming that your client isn't going to be using CC3 him or herself, so the CC3 snapping grid is only relevant if you need it to align things in the map with the grid...

• Use the Select Points option both times, and the set snap grid option only for the first grid of smaller hexes. That's the snap grid you will use to align the grids with each other.
• If you draw the 5ft grid first, drawing it to one side of the map a little larger than the map itself, when you draw your 50ft grid over it pick one of the intersections of 3 small hexes as the starting point for the 50ft grid.
• Once you have both grids drawn, group them so they can be moved as one object, switch on Attach, and use the move tool to pick them up by the intersection you want to place at the origin of your map. Then type the coordinates 0,0 and hit enter. This will align the intersection at the origin of your map, which (unless you have moved the frame and screen around by hand) should be the bottom left corner.
• The User snap grid is useless to you now, even though you created it with the small hexes, so right click the Grid button and pick it and delete it.

I've just drawn this one using the "select points" option. I drew the first 5ft grid allowing it to generate a snap grid, then used that snap grid to pick the select points position for the 50ft grid.
