Generating the PostScript File
AutoCAD (at least since version 2000) has an “Export” command under the “File” menu to export (Encapsulated) PostScript files, with the “.EPS” suffix. The most important detail when using this function is correct scaling. In the “Export” dialog box for AutoCAD 2003, there is an “Options…” feature under the “Tools” menu (upper right corner). Typically it will be desirable to assign a one-to-one correspondence between “Output Units” and “Drawing Units” for “Scale”, with appropriate “Size Units” (inch or millimeter) pre-selected. It is very important to verify that the output scale matches design intent by inspecting the PostScript file after it is exported.
