Can you be more specific?

All objects contain their coordinates in one form or another. Using
IDLgrWindow::Select allows you to get the reference of the object(s)
that you click on and from there you can determine that object's
position in world space.

If you need to know *where* on an object you select you will either have
to break up your object into smaller pieces or roll your own
ray->triangle intersection code.
