    I am currently using a lisp routine to work on some of the blocks in
    drawings I receive, and the blocks are selected very simply :

    (setq ss (ssget "X" (list (cons 2 "blocketyblock"))))

    Now I have a drawing with only 1 block def, where all blocks are
    differentiated only by the value of an attribute called "type".

    How do I refine my selection to only include blocks where the "type"
    attribute has a certain value?

    All input greatly appreciated.

    Attributes are entities by themselves. Search for ATTRIB entities.
