It does not like. I think V20 may open up STL data but I don't know what it will do with it.
At one point UGS was giving out a macro that would bring in every point one at a time. It was slow and a bad idea for files with lots of points.
If you really want to do a good job of reverse engineering the truth is you will need a package that is designed for it like Imageware or raindrop or paraform.
