Zonepoints and Z cords

[Sakrateri]

Hey there , Im making some really nice zones with this but have on problem, When I make zonelines it does not sem to matter what i set the z axes for the target zone to it always zones me beneath the world, I am curious , what does the ignore do exactly for the target zone points? , i have tried it checked and unchecked. And what exactly does infinite z do ? I have tried that checked and unchecked , the x and y seem to be great but that z is killing me , any ideas?

Thanks alot for this program it really is a great way to allow people to get out of the tedium of all the stuff thats been seen before.
