in reply to A data selection problem(in3D).

While you can always get good quality answers at our site, this is not a place to have others do your homework for you. You need to show that you have at least done a minimal amount of work on the problem otherwise we are just allowing you to do the same thing as copying your classmates answers. You are not doing yourself, your classmates or your teacher any favors by having us do your work for you.
