 There are I think only 3 simple rules:

 1. one scrap should not overlap itself
 2. one scrap scrap should not contain more then approx. 100 m of 
 passages in 1:100 scale (MetaPost limit)
 3. passages should be divided into scraps in most simple places - if 
 you will follow this recommendation then "equate scrap1 scrap2" is 
 enough for joining two scraps.
