ssget at a specific point

    I am trying to use the following code to check for the presence of an entity at a specific point but the results are affected by
    whether objects fall within the current pickbox.

    (ssget point_test '((0 . "LINE")))
    Is there a way to select at specific point, perhaps even allowing for a specific amount of tolerance?

    I have also tried:
    (ssget "c" point_test point_test)
    when zoomed out far enough returns nearby lines as well.

    Thanks
    Cliff

    What about setting the pickbox to zero beforehand, and then restoring it
    later?

    Try using "nentselp" instead, then if it finds an entity test to see if it is a line...... but even this won't work if the point
    happens to be an intersect point of 2 or more entities.....

    HTH,
