Dear Jennifer :

Note that I was able to get the BLKATTPT.LSP LISP command to run fine with your drawing file. Here is the AutoCAD command sequence (with some comments I have inserted for your reference):

Command: lsp
AutoCAD Express Tools Copyright =A9 1999 Autodesk, Inc.
Initializing...
AutoCAD Express Tools Copyright =A9 1999 Autodesk, Inc.
Enter an option [?/Commands/Functions/Variables/Load]: L
(a dialog is displayed, select the BLKATTPT.LSP file)
_.appload BLKATTPT.LSP successfully loaded.
Command: blkatt2pnt
(note that this command starts the LISP routine)
Block name (Use * for all): POINT
(note that this is the name of your blocks containing the point
data)
Layer name of the blocks: PNTSTIC
(note that this is the layer that the blocks were inserted on)
Layer name to create the points: _NEW_ELEVS=20
(note that this has to be an existing layer)
Tag name to extract Z value from: ELEV
(note this is the attribute tag containing the elevation data)
Color for the new layer: WHITE
(you can make this any color you want)
264 blocks found, 264 points created.

If you have any additional questions or need any further information, please contact me again.

Sincerely,

Chris E. Maeder, M.S.
