When Speed bumps go bad

Ever spent hours trying to line up tunnels on the z axis. Ever had stacked walls that over lap so bad that when you see them your eyes want to bleed. Ever tried to line up bridges and encountered a speed bump along the width. Well Absolute Height is the quick and easy answer to these problems and more.
With AH, you can adjust all the z axis in a group of objects all at one time without having to take in consideration the diverse changes in landscape in a matter of seconds.


In other words turn this...

into this...

or this...

into this...

But what is Absolute height you're asking.
Absolute height is the distance above the base of the terrain. In other the words, if you dig a hole in your terrain, it can only go down so far. Because, unlike the real world being a sphere, the LW world is flat. So it has a bottom at Absolute height of 0. Nothing can be done below this level. When you place an object in the MED it defaults to 0 Z of the terrain which is piles of "dirt" on top of the base.

Now how to apply this knowledge.

As far as tunnels go, they are done the same way except the reference height comes from the tunnel entrance. You have to get the absolute height of the entrance and subtract 5 or 8 from it depending on the type of entrance it is. So if the absolute height of the entrance is 106/000 your tunnel will be either 101/000 or 98/000.
