I think you'll find that a 3d solids properties are encoded and not available through either Lisp or VBA
that's not taking into account "properties" like Centroid, radii of gyration etc which can be accessed.
The other stuff like whether it's a cylinder or box or cone aren't available, neither are props like height, length, width. You have to use bounding boxes, and ucs's and a lot of match to calculate the size of a solid
