CAD Manager Chris Wade provided this routine to strip out AEC objects — which are created by vertical applications such as Land Desktop — from drawings. Load the LISP file and then run it by entering Eaec at the Command line. The routine will make a copy of the drawing and work on the original, using the Export to AutoCAD command.  This routine could be improved by declaring the variables as local, but it runs well as-is and will be a great help to those who need to strip a drawing down to its basic elements before sending to a client, for example.
