    Hi everibody, I'm a novice user of AUTOCAD and I'm starting learning about
    AUTOLISP and Autocad customization...I need a routine to select the face of
    a solid and make it become an entity (to find the centroid of that surface
    then, that's what I really need)...
    I thought the way to unambiguously identify one of the solid's faces could
    be by selecting 2 of their sides, but I've no idea of how to translate it in

    Any help will be very appreciated

    Thanks a lot
