The AutoCAD LT PostScript support file (aclt.psf) is the master support file for PSOUT, which exports drawings in PostScript format. This editable ASCII file is divided into sections that control font substitution and define PostScript fill patterns. It also includes prologue sections that consist of PostScript-coded procedure definitions and constants. The sections of the aclt.psf file can appear in any order, but for reasons of efficiency the *fonts section should appear first in the file.
The PSPROLOG system variable (accessed from Options in the Export Data dialog box) instructs PSOUT to reference an additional prologue section that you create in the aclt.psf file. By creating a prologue section and placing PostScript code in it, you can customize the appearance of PostScript output in a number of ways. A single prologue section can contain many PostScript functions.
Each section of aclt.psf begins with a section name that is preceded by an asterisk in column 1. Lines beginning with a semicolon are treated as comments in all sections of this file.
The standard aclt.psf file defines the Type 1 fonts formerly supplied with AutoCAD LT, as well as all PostScript fonts that appear in Adobe Type Manager for Windows, the Adobe Plus Pack, and Adobe Font Pack 1. Because a font downloader is not supplied with AutoCAD LT, you might want to modify aclt.psf to reference fonts that are resident in your printer. If a font downloader was not supplied with your printer, you can obtain one from the Adobe forum on CompuServe.
