[Equest-users] Shading of windows

Ah, a question that I can easily answer!

A building-shade is tied geometrically to a building, while a fixed 
shade is not, i.e., it's tied geometrically to the global coordinate 
system.  As an example, one should model the shading cast by neighboring 
structures as fixed shades, and model the shading of building elements 
like overhangs and fins as building shades. This distinction is handy 
when one wants to rotate a building model on a given site.
