Map Creating in XML

How to generate coordinate independent sectors?

I want that two sectors have an origin in (0.0,0.0,0.0) but the mustn't be overlapped.

I made a sector that is a corridor that ends in a portal that leads to the middle of other sector, which is an spiral. The end of this spiral have another portal that leads into this corridor again. And then goes on and on and on and on and on.. .... .... wink

Well, my problem is that the two sectors have the same origin, at (0.0 x3). and I thought that the sectors had independent coordinate systems. Is there any way to do this??

It's quite urgent.

Thx in advance
