Heres a tutorial how to drag and drop part of a map from one map, to another. It's simple and easy to do. I used Remeres Map Editor (8.5) to do this.
First,
You have to have 2 maps open in 1 editor. This is so you can copy part of a map to another.
Second,
You need to copy the surface ground. Holding shift and dragging your mouse cursor over the map area you want to copy will highlight it.
Thirdly,
You need to right click the area you have selected and select "Copy".
Fourthly,
Go to the next map (the one you want to paste it on) and right click on the area you want to paste it. Right click and select "Paste".
Here you can see both tabs. The map as been copied.
Fifthly,
Then do the same to the above ground part of the map. You need to line the yellow square up with the stairs. If it's not correct, it will be dark yellow like this;
if its correct it will be light yellow, like this;
Now, your map should be copied over to the other map.
Hope I've helped. If I have, please Rep++ me.
Thanks.
