10.1 C:\Program Files\AutoCAD R14\Support\ACAD.PGP (Supplied with base setup).
      This file has been altered to allow a shell out to Windows Explorer, Notepad and other external programmes.
10.2 C:\Program Files\AutoCAD R14\Support\ACAD.LIN (Supplied with base setup).
      Extra linetypes have been added to this file.
10.3 C:\Program Files\AutoCAD R14\Fonts\ISO3098B.SHX (Supplied with base setup).
      Additional characters have added to this file e.g. XX², XX₂, XX³, XX₃ etc.
10.4 C:\Program Files\AutoCAD R14\Support\ACAD.LSP (Supplied with base setup).
      This file has been created to setup new drawings for limits, text size, line scale etc. according to a user defined scale factor and sheet size. It also loads various other LISP routines.
10.5 C:\PKAY\CHSCALE.LSP (Supplied with the base setup).
      This file has been created to allow the scale factor to be changed from what was setup with the acad.lsp file.
10.6 C:\PKAY\CH.LSP (Available to customers of source files only).
      This lisp routine is useful for tidying up blocks after they have been created. In all the drawing using these packages the blocks are all on layer "0" and use only "ISO3098B" text font. If during the course of producing a drawing, blocks are created and Wblocked using other than layer "0" and text fonts other than "ISO3098B", then the block layers and fonts can be corrected using this routine. The block is then purged of all other useless information.
To start this process first creates a file, e.g. "FIX.SCR", as follows: -
OPEN [blockname1] (LOAD "CH") ENCH NEWS NEWA WB QUIT Y
OPEN [blockname2] (LOAD "CH") ENCH NEWS NEWA WB QUIT Y
OPEN [blockname3] (LOAD "CH") ENCH NEWS NEWA WB QUIT Y
OPEN [blockname4] (LOAD "CH") ENCH NEWS NEWA WB QUIT Y
OPEN [blockname5] (LOAD "CH") ENCH NEWS NEWA WB QUIT Y
Add extra lines as needed.
10.7 Batch Plotting.
      Use the Batch Plotting routine EBATCHP.EXE supplied with AutoCAD® and located in the C:\Program Files\AutoCAD R14\Support\Ebatch directory.
