    if you use the vba "explode" method on a block..The block
    remains intact and a copy of the objects that make up the block are
    created..you can now extract the data you need from each entity and
    then delete...

    Why work so hard?

    Try somthing like this

    Dim TheEntity As AcadEntity
    Dim TheBlock As AcadBlock
    ..
    ..
    {get your block here}
    ..
    ..
    For Each TheEntity In TheBlock
    {Process for each entity here
    Next

    It is possible to find out what entities exist for the block in
    question by going through the collection of blocks and finding the one
    that you are after, then iterating through the subitems (i think that
    is what its called) of that block to work out what is there (its the
    same as exploding the block, but without the exploding).
