3D Tool looks like it might be an option. It's pretty much in the same price range that Deep Exploration used to be in.

I've given up on asking engineers to do anything other than just give me their original files. It saves weeks of whining, complaining and headaches when I handle everything myself. Whenever I've asked an engineer to save a file in a format other than the original, it's as if I'd asked them to build a rocket to the moon out of cardboard and a Ronco Pocket Fisherman.

No offense to any engineers out there. ;-)
