    Hi Guys,
    Need some help with this one please.

    (setq pt1 (entsel "Select Object :"))(terpri)
    returns :- (<Entity name: 400b21a0> (10197.4 31317.6 0.0))

    How do I extract the floating point so its values can be (in whole or part)
    used later in the routine?

    Rgds,
    Steve

    Steve,

    (setq pt1 (cadr (entsel))) returns the point picked. The second item in the
    list.

    Study those help files, dude.

    Steve,

    You're welcome.

    But in fact is probably makes more sense to take your initial approach:

    (setq ent (entsel))

    This way you can extract the point picked (cadr ent) or the ename (car ent).
    I can't recall how many times I thought I would need only one or the other,
    only to find later I needed both. Now I'm rewriting the program to cover my
    shortsighted mistake.
