Can I do a quick 2D raytrace to see where the light is going in a particular plane?
Certainly. We have several 2D lamp models which you can find in the Lamps.xls spreadsheet, including a point source as well as T5 and T8 lamp cross sections. Just import these like any other lamp model, placing them where you want to see the raytrace. General guidelines are as follows: 10,000 rays, 100% update frequency, and turn on 3D ray display with at least 500 rays. Keep in mind that because this process is only meant for seeing ray paths, the candela curves and illuminance planes will not be relevant. Additionally, the Parametric Optical Design Tools (PODT) provide an excellent way to determine how reflector sections are aimed and easily change the aiming without redrawing things in CAD.
