Question
HI, my name Bill Curtis, I'm an Irrigation System Designer.  I know there is a Lisp file made to suit my purpose, but I don't know where to find it.  Perhaps you could tell me or I could pay you to make it up for me.  It's simple really, I'll explain what I need.  I insert several sprinkler head symbol's into the drawing, the symbol's have a "gallons per minute" attribute in the block.  Next, I want to draw a polyline around a group of sprinkler symbol blocks and have a lisp file tell me how many gallons per minute are within the boundries of the pline.  I don't care how the display is shown, I only care to know exactly the total gallons per minute within the area I encircled with the pline, quick and dirty.  I know about the eattext command, but that is way to slow.  If you can help me please let me know.
Thank you
Bill Curtis

Bill:  I am working on a solution.  Got some help from somebody on a subroutine.  Will work on this over the weekend.

OK, Bill I have code that works.  Currently the code looks for a block named "sprinkler" and the block is to have but ONE attribute which will be an integer (no decimals).  All the sprinklers either on or inside the LWPOLYLINE selected will be evaluated for the attribute value therein.  The values will be added and the total will be reported on the command line.  If you want to change anything about this let me know.  I'll give you a call call tomorrow morning.  Our morning starts about 3 or so hours later than yours does, so, you should be awake.  If I don't reach you this weekend, I'll talk to you on Monday.
