   I.  INTRODUCTION

       LOCKDWG is an ACAD utility intended to be used for the purpose
       of making it difficult for those who wish to alter an ACAD drawing
       file.  LOCKDWG does exactly what it sounds like - it locks an ACAD
       drawing.  Why lock a drawing?  If you have ever had your drawing
       changed by someone when you did not want it to be changed you are
       among the many of us who have been waiting for this little gem.
       LOCKDWG is of course not 100% tamperproof, nor is your ACAD drawing,
       but LOCKDWG can make it very difficult for those who want to make
       drawing changes without prior approval.


                                       1



       Here's how LOCKDWG works:

       First, LOCKDWG does not lock your original, it locks a copy of your
       original.  A new drawing is created by LOCKDWG which contains a
       block of your original drawing with a 2 Z scale factor.  This
       makes the block permanent, i.e. it can not be exploded.  Now, to
       keep those creative minds busy the block name is removed from the
       drawing database, so that the negative scaling can not be reversed.
       That's all there is to it.  The recipient of the locked drawing can
       not make any changes to your drawing and all your time and effort
       is protected.

 II.  INSTALLATION:

       By now you have already unzipped the distribution copy, so we'll
       move on.  LOCKDWG.EXE can be placed anywhere on your hard disk,
       but you must set a DOS environment variable before using LOCKDWG.
       A good way to accomplish this is to add the following line to
       your AUTOEXEC.BAT file:

                       SET DWGLOCK=C:\ACAD

       Here, the DOS environment variable DWGLOCK is given a value of
       C:\ACAD, but you must substitute C:\ACAD for the actual path of
       ACAD.EXE on your system.  If this is confusing or doesn't make
       any sense to you then please consult your DOS manual or ask for
       help from your computer guru.  Reboot your computer.  If you get
       a DOS message stating:

                       Out of environment space

       then you must increase the memory allocated to the DOS environment,
       perhaps by placing the following line in your CONFIG.SYS file:

                       Shell=C:\Command.com /e:384 /P

       where, the value assigned with /e: is the number of bytes to allocate
       for the environment.  The /P tells DOS to find your AUTOEXEC.BAT file
       on the root directory of your boot disk and execute it.

III.  USAGE:

       At your friendly DOS prompt type in:

       LOCKDWG DRAWING1 DRAWING2 <enter>

       where:
           DRAWING1 and DRAWING2 must be unique file names.
           Please specify the path of these file names.  No
           file extension is required, .DWG wil be assumed.
           Please make sure you have:
                                     SET DWGLOCK=ACAD_PATH
           in your AUTOEXEC.BAT file.  Where ACAD_PATH is the
           drive and directory specification for ACAD.EXE.

       LOCKDWG will create DRAWING2, a locked copy of DRAWING1.
