Rad, this comment may not be useful (or maybe way too obvious!). I had some trouble with b3d files from Quill3D, (a great,low cost program by Birdie). The thing is Quill3D sets the handle point on objects on the center crosshair while you are designing it, and saves it there. To change the center handle- move the object in the design program, and then save and export it to b3d format. Does this work in 3ds Max? I don't know.....try it for yourself.
