I don't think I have any more info now, than
I posted in your previous message. There may be a tutorial out there that will explain how to make the hexagon map, but I can't think of one. I would have to search. And of course, you could search as well.
I don't think I specifically suggested using Tiled Clones with the Y shaped path (that I showed in your other message), but that should work, once you figure out the values for the Shift tab. And I'm sure you'll be able to find a video tutorial on using Tiled Clones dialog.
For your attempt at a 2 sq meter file of 1 cm hexagons, I would definitely make it with the Y path, rather than with hexagons. Because with hexagons, every single edge of every single hexagon is doubled (except for the ones on the edges of the map). And every node of each hexagon has the node of the next hexagon on top of it. And file size is your enemy for this project. So you will want to try and reduce bulk at every turn.
Hhmm.....well unless you want these hexagons to be filled with different colors. If you want each hexagon to be filled with a different color, you'll have to use whole hexagons to construct the grid. If you use the Y paths, they won't be distinct hexagons. Each one would be part of the next. So that part depends on your ultimate goal.
Although I suppose you could use Arrange dialog, and Polar Coordinates section. I'm not familiar enough with it to vouch for its precision. It may be perfectly precise, I've only just played with it a couple of times. I definitely haven't seen any tutorials for that - although you might find instructions by searching the forum.
I can vouch for precision with Tiled Clones dialog, as long as you have the proper values on the Shift tab. And of course Snapping provides precision. Personally, I could create such a map as quickly with manual snapping of hexagons, as with figuring out the values for the Shift tab of Tiled Clones dialog. (That's because it only uses percent for units, so after you figure out the proper unit values, you have to convert to percent.)
Note that if you try to create the whole map at one click with Tiled Clones, it could take....geez....a few minutes or more, depending on your computer specs. I think I explained about that part in your other message, that your computer specs will be the limiting factor, more than Inkscape. If Inkscape crashes when you click Apply, you'll know you're asking it too much.
One thing I'm curious about. Where will this map be viewed? On a computer screen? Or on a printed banner? On something like a banner, I doubt that 1 cm hexagons will be visually identifiable. I guess you'd have to get almost within arm's length to see that they aren't circles.
