[Solved] Middle of Map and Symmetrical Terrain

[MaskGT]

Hi,

Maybe it's a strange question I'm asking but I need to know this.

How to make a cliff in the middle of the map, so that there would be equal distance from left, right, top and bottom?

How to make 4 Symmetrical areas?

Look at the picture.

Thanks,
MaskGT

EDIT: I solved this problem my self.

View > Grid > Large to reveal the grids. Then the only thing you are required to know is how to count. You will find the center of the map with great ease.
