Very nice work!

@Loopysue Thanks. I'm mystified by that behavior. It doesn't seem to happen all the time.

@JimP Thanks, too. I tried that and it seemed to work, but then the Import File thing did its thing.

Another update.

I find if I move the cursor just up the left hand side, the image goes inside the map rectangle instead of going the other direction so sort of draws correctly.

This web site lets you compose the appropriate symbols for unit and equipment using the NATO/UK MS2525 and APP 6 Standards documents.

This site has several files you can download that provides NATO and other symbols/vehicles/planes/etc.

And this web site has many diagrams of ships, ground vehicles, and aircraft in constant scales.

I myself frequently use Brute Force and Ignorance (BFI) to get through my map making!
