Granted... most Brycers are artists and probably not concerned with scale... other than eyeballing an approximation of one object's size in relationship to another... but in my field... when we draw an architectural model in formZ (always drawn to scale) say and then import it into Bryce to render... and then want to boolean something in Bryce to add to the model (a 6'-0" x 3'-0" x 30"h table say)... then I know to make it 2.40 x 1.20 x.60 Bryce units... I am assured of it's proportion in relationship to the model... I guess this would only apply to a few in this Forum... but an interesting fact to know.
