I used the ies2rad utility and with getbbox on the generated rad
file, I get bounding box dimensions that don't correspond to the
lamp geometry. For example a fixture with a T8 lamp returns a
getbbox dimension of .1,.1,.1 (xyz). The ies file I used includes
mgf data and a .dxf file was generated (via ies2rad or brad). Is
there a way to confirm the fixture/lamp scale and preview it???
And in general, should the lamps loaded via brad's libraries appear
as lamps or geometric emitting objects? Eg.
