[Therion] how to do multilevel scrap

[Bruce]

>2. you drew two scraps from two separated parts (20101106_2_p1,  
20101106_4_p1. Correct way is to name each part as separate scrap.  
Very important it is in second case where each part belong to  
different level.

I have tried to explain this here

en_scraps_in_loch_and_google_earth
although it could do with some pictures I expect.

If it could be explained better, or if there are peculiarities that I have
left out, then please edit the page, or send me suggestions.
