Thank you all for your help.

I tried magnets, of course, but they are a chore to use this way on curved body part objects like breasts that will deform heavily when pressed towards a flat surface. To make a curved surface flat with a magnet, the falloff curve is to be tailored to match the form of the breast. Since the breasts of a good modern model are not circular-symmetric, there is no good solution.

I tried to locate the Eureka script, but I could not find it. What comes near to it is NoPoke. That script searches the limiting prop geometry from a mesh. For my purpose it could be much more simple because my limiting geometry is decribed mathematically: Y==0). It basically does the same thing, though.
Was the Eureka script simpler; a predecessor of NoPoke maybe? If so I would appreciate any pointers where to find it.
In the mean while I will try the Wings route.
Again, thank you all.
