@SPARKY1922 Here is the first of three tutorials. This one will be needed if you want to try to put a dive lot into a different world - or even in the same world but into a different place from the lot on which it was originally built. Also I use it for moving the flag down a bit and that's how I stop the mermaids from jumping into the air when they cross the dive lot boundary.
Here's the link to the newest tutorial.

Its on the SetImportedTerrainOffset cheat and is used if you place a lot and it is too high or too low for the surrounding terrain.
