AutoCAD® is a general-purpose drafting system designed with an open architecture so you can customize and extend its many features. As a result, you can expand and shape AutoCAD according to your needs.
You can change the default directory structure for the program and support files to suit your needs.
You can create customized templates to use in the Publish to Web wizard by modifying one of the Publish to Web template (PWT) files provided. Use any HTML editor or text editor.
You can define external commands that run from within AutoCAD. You can also create command aliases for AutoCAD commands in the acad.pgp file, an ASCII text file that stores command definitions.
Action macros can be used to automate repetitive tasks by recording a series of commands and any values entered.
