Corridors
This is a short, straight-forward tutorial designed to introduce a way for adding a single primitive to two layers, or, in simple English, building a corridor between two different worlds. As a mapper you probably noticed that when adding room primitives to your map, they'll only be added to a single layer, and might create difficulty when having a single big complex (for example, a single building) with many different layers.
I assume you have some knowledge of the editor, because otherwise the above paragraph would've been mostly garbage to you :) Therefore, I won't detail each and every click you have to do.
The starting geometry is two conus primitives, rooms, both sized 32x32x32, one on position 0x0x0 and the other on 34x0x0. Make sure to add the second room to a different WorldBase layer, either by dragging the appropriate entity in advance or using the 'l' key. Mark both of them as Zoning and Anchored.
Now you'll have two worldbases. Build a small corridor between them, size it 2x4x9 and position it 17x0x0. Add it to one of the layers; then build another small corridor, same properties, but use the combo box on the top left corner of the screen to add it to the other worldbase. No rest for the wicked though; there is still one important thing to do: enter one of the rooms, and pick the polygon at the end of the small corridor. Mark it as portal and passable. Do the same for the other room, and test the level.
That should do the trick. Short and simple, but can prevent a lot of headache.
