DESCRIPTION
------------------------------------------------------------------

This LISP routine was designed to calculate voltage drop based on NEC methods.
Works with different type of circuits and wires, allows temperature correction.
Results will be inserted directly in the AutoCAD drawing. 
Capable of using Scale Master II or higher Digital Plan Measure 
input device (www.calculated.com).

PROGRAM FILES
------------------------------------------------------------------

vd.lsp       main routine
vd_draw.lsp  supplementary routine
vd.dcl       dialog file
vd_matt.vdc  data file
vd_comm.vdc  data storage file
vd_tem1.vdc  temporal data file
vd_tem2.vdc  temporal data file
vd_tem3.vdc  temporal data file

LOADING AND INSTALLATION INFORMATION
------------------------------------------------------------------

To install the program UNZIP all files to the directory in which the file
"acad.exe" is located.

AutoCAD provides many methods of loading AutoLISP programs.  
Two of the most common are discussed in the following.

Method 1
--------
Use AutoCAD's "appload" command to load "vd.lsp" file.  See AutoCAD's 
command reference for further instructions.  To start the routine
type VD at AutoCAD command prompt.

Method 2
--------
A line of code may be added to the "acad*.lsp" file such as the
following:

(load "vd")

This will automatically load the program each time a new drawing is opened.
To start the routine type VD at AutoCAD command prompt.

"acad*.lsp" file for AutoCAD R12 is "acad.lsp"
"acad*.lsp" file for AutoCAD R13 is "acadr13.lsp"
"acad*.lsp" file for AutoCAD R14 is "acadr14.lsp"
"acad*.lsp" file for AutoCAD 2000 is "acad2000.lsp"

IMPORTANT!!!
Before modifying "acad*.lsp" file save it under different name
to prevent accidental file corruption.
