Wel, Ross C, that doesn't make sense. PositionEntity for small values works OK; it's when I try to position the camera entity farther out, that I run into problems. My machine at work here won't run 3D, so I'll have to wait until I get home, but I am doubtful the suggestion you offer will work. (But, I'll try it, and the ResetEneity command suggestion, too, from WolRon.) As I mentioned before, PositionEntity works OK, no matter how far out I go, before I add all my mesh objects (the DrawMap subroutine). It's only after I've added them to my 3D world, that the PositionEntity for the camera goes bonkers.
