How do I make compounds in the level editor?

Yes, we are here to help!
HINT :
When you have pressed b -> BE CAREFULL with connecting new walls\etc.
It is a bit weird but then sometimes the next walls you place and attach to the compund"s" don't fit anymore.
AWNSER :
When you have selected for example 1 room with B,
Then when you have placed the compound, RE-PRESS B and move your { Un-compounded} room a little bit farward and backwards.. -> you will see the walls change a little bit of their position. <- THAT is how it must be!
If you do not do that, there is a possiblility tat you next walls\ etc, won't be placed how you want.

Try out what i just wrote here above, maybe you see what i mean.
It's VERY annoying when you have made a map and the hights and axes don't attach!
You don't want to MANUALLY have to replace the halfh map cause due the COMPOUND.
