Michael Stachulak provided AIA Standard Layers, a must-have utility for architects who create all the layers needed for the American Institute of Architects standards according to the 1997 AIA CAD Layer Guidelines. The utility creates a long list of layers with linetypes and colors. Layers are created only if they don’t already exist in the drawing, thus the utility will not interfere with the use of prototype drawings. To use this utility, simply load the LISP code and type AIALayers2009 at the AutoCAD Command line. (Note that a separate download file, AIALayers.LSP, is included for pre-AutoCAD 2009 compatibility.)
Update (November 11, 2008): Tip author Mike Stachulak provides a correction to the original code and updated the tip to include expanded applications. The corrected/updated files are now included in the file download.
Mike explains the changes as follows:
I have written Autolisp files to include existing, new and demolition layers also based on the Architectural Graphic Standards, Tenth Edition of the book and version 3.0 of the CD-ROM. I have also included a plot style table (pen assignments) AIA Monochrome.ctb for plotting. Demo.lin is included for the demo linetype. Since the release of AIAlayers2009.lsp & AIAlayers.lsp, I have noticed an error in the Architectural Graphic Standards. There was an extra letter "T" in "A-ELEV-PFIXT" and "I-ELEV-PFIXT" which is what these two .lsp files are based on. The status field should read "-PFIX". I have changed the two previously released .lsp files to include these changes and attached them with the new Autolisp files.
