What's your Strategy?

The elevation data is the difference. You can't by default place ships at positive elevations, or for that matter facilities in negative elevations even though there are many places around the globe where both are valid (but the game doesn't have a way to know that). There are a few areas in the global where this is overridden - suez+panama as I recall but beyond that you will run into this issue, as you also will with basic navigation of units that in encounter invalid terrain for themselves even when it's not in real life).Nikel wrote: Sat Apr 23, 2022 4:23 pm There is a community scenario called Caspian Darts by Kevin Kin with ships in the interior Caspian Sea, what is the difference with the Great Lakes?
Edit: oh, I see that the Aral Sea is also unavailable, which is more correct because it is mainly dried.
You can place them in a few spots I believe where the depth is below sea level but that wouldn't be Lake St. Clair obviously. That said, you could put a vessel in California's Salton Sea (or sail it over the land in the Imperial Valley!) since it qualifies as being under sea level.blackcloud6 wrote: Sat Apr 23, 2022 2:14 pm I tried to place a ship in Lake Erie and also in Lake St. Clair in the shipping channel and I get an error that says you cannot place a ship in land. So CMO considers the Great Lakes as land? Can this be fixed?
OK, thanks.KnightHawk75 wrote: Sun Apr 24, 2022 3:29 am

That said you can actually overcome this if you truly desire by using lua to place them, and lua to move them (by constantly overriding the default navigation logic and having it follow your own course, it's not for the faint of heart though). Another way you used to be able to over-ride this regarding ships is placement of lots of ports and having their access-arcs all overlap slightly, that used to work for example to let something navigate down the St.Lawrence river or say to clear up navigation problem with elevation data around pearl harbor or other similar places.
I believe though the game let's you place them if the under water elevation is below sea level. I believe Lake Superior has depths that extend below sea level, as does Lake Michigan (and possibly parts of Huron). I don't think Lake Ontario or Erie have anything that qualifies.Nikel wrote: Mon Apr 25, 2022 12:40 pmOK, thanks.KnightHawk75 wrote: Sun Apr 24, 2022 3:29 am

According to the wikipedia, the Great Lakes elevation is between 75 and 183 m above the sea level.
The Caspian Sea 28 m below. And the Aral Sea 30-40 m above.
and up it was very clever.There is a work around I used on the St. Lawrence to get to Quebec City. I just placed piers along the way and had the cones overlap the river to make it traversable. I then grouped them all together and voila, river sailing!

Very likely not, could have air defense stuff also not work when placed in negative elevations unless the munitions engine has entries for negative and positive altitude entries, etc. So it's something to watch out for and test if trying to build real scene.SunlitZelkova wrote: Wed Apr 27, 2022 6:58 am Do underwater weapons work with the "using ports" technique though? I tried to do this in a test at Pearl Harbor, but the Type 91 torpedoes would not work.
