Battlefield 2 - Map Creator

I downloaded the bf2 map creator today, but do not understand how to use it:P I wanna know how to create buildings, water, grounds, etc.

Is it someone with experience ??? Please answere me ;)

It isn't going to be nearly as straight forward as you think it is going to be.

You need to understand 3d modeling and stuff to make maps in that game.

But is it possible to save my works?Redrum000
