I read the discussion on cavechat - one very important thing - make  
your sketches in a cave directly in the scale so you will be able to  
orientate in  the system in any moment. Check the therion proctractor  
- very useful tool for this.

There is much more easy to draw maps in therion from such in scale  
sketches.
