I've actually been meaning to try BRL, I even have it on disk here. The problem is switching to another format in FG. There are a lot that theoretically work in plib, but using those loaders in fg is not as well understood from the model builder's point of view. Also, not all the loaders provide the same functionality. Is there an easy way to get from BRL to .ac? Maybe I should be looking into BRL and either dxf or ase. Anyway, I have found that using direct numeric input in Blender is fast and easy. Like everything in Blender, it is tempered by the basic steep learning curve.
