    any good primer on 3-D cal expressions? I need to solve euclidean problems:
    1. distance of a point to a plane
    2. xyz position a line intersecting a plane
    3. new coordinates of an object after rotating
    etc
    thanks

    Looked in the help already I assume, and found it not very?

    Your #1 is a built-in function. I wrote a routine called 3D-Projector.lsp a
    while back (with help from TomD) to project a point onto a given plane that
    you might look at. It might give you an idea on how to try your #2. It's on
    my site. It basically does some coordinate translation.
