Hi guys,

I am looking for a lisp or a VBA program that will total up the
(gpm) gallons per minute for an irrigation plan.

I have the irrigation sprayhead symbols made as blocks with
attributed infromation in it, the attributed info in the block is
the model of the sprayhead, the gpm's that sprayhead is, and the
unit price of the sprayhead.

So what I looking for is a lisp(s)/VBA to do two things.

The first is to be like the "bcount" command build into AutoCAD and
have it count up all the blocks that I either selected or placed a
window around and display the total gpm's for that system.

The second one is to be able to select the blocks one by one and as
I do this it adds up the gpm's on the screen or on the command line,
so I can size the irrigation pipe.

I am using AutoCAD 2002

I hope you can help me or if not maybe you can direct me to someone
who can

Thank for your help

Kyle C.
