Could not "Drop to 'something'" be done using a Python script? The one issue here is that to drop to 'something' requires that one thing be selected and you subsequently select a target. Otherwise you would have to calculate all possible targets in the scene using 'rays' to determine the object (and I should know, I wrote a plugin for C4D to drop to a target). Once you go beyond dropping to planar surfaces, you have to deal with some extremely difficult maths in order to consider minima and maxima (which brings up issues of false minima/maxima) and other juicy tidbits of fun. Even when the target is specified, you still need to do collision detection starting from crude box-box overlap and ending with point minima/maxima collision. I'm sure that most of you have seen what it takes to do collision detection in the Dynamics Room... :)

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
