AutoLISP / Visual LISP

AutoLISP is based on the LISP programming language. Because AutoCAD has a built-in LISP interpreter, you can enter AutoLISP code at the command prompt or load AutoLISP code from external files. Visual LISP (VLISP) is a software tool designed to expedite AutoLISP program development. AutoLISP and Visual LISP is often used mutually but AutoLISP is only a subset of Visual LISP. Visual LISP was incorporated into AutoCAD 2000 released in March 1999, as a replacement for AutoLISP.

Visual LISP technology is a tool for code creation in the AutoCAD software application. It is a full-featured, interpretive programming language that you can use to call AutoCAD commands, system variables, and dialog boxes. Visual LISP offers a complete development environment, including

• Reduced development time using the integrated development environment (IDE), which makes it easier and faster for users and developers alike to create, debug, and deliver AutoLISP-based applications
• Access to Microsoft ActiveX objects and event reactors
• Source code protection against theft and alteration
• Operating system file-operation functions
• LISP function extensions for list processing

In February 2018, BricsCAD V18.2 came with BLADE, the BricsCAD LISP Advanced Development Environment. See this blog post.

LISP is used by CAD applications like AutoCAD, BricsCAD, DraftSight, GstarCAD, CADopia, IntelliCAD, progeCAD and ZWCAD.

With AutoCAD 2021 improvements have been made to AutoLISP and DCL. These improvements include:

Free Autolisp

• Cross-platform development with Microsoft Visual Studio (VS) Code. See get started page and videos here.
• Unicode support
• DCL is now supported on Windows and Mac

Miscellaneous tips and trix for AutoCAD AutoLISP

; AutoLISP function to convert degrees to radians
(defun dtr (a)
(* pi (/ a 180.0))
)
; AutoLISP function to convert radians to degrees
(defun rtd (r)
(* 180.0 (/ r pi))
)
; Example on how to remove the last element or item in a list
(setq lst '(1 2 3 4))
(setq lst (reverse (cdr (reverse lst))))
; result is (1 2 3)
; Example on how to right rotate a list 1 step
(setq lst '(1 2 3 4))
(setq lst (append (list (last lst)) (reverse (cdr (reverse lst)))))
; result is (4 1 2 3)
; Example on how to left rotate a list 1 step
(setq lst '(1 2 3 4))
(setq lst (append (cdr lst) (list (car lst))))
; result is (2 3 4 1)

Visual LISP example how to delete all empty layouts (tabs). If the layout has been activated it will contain a viewport object and will not be deleted by this function.

In previous version (= nil (ssget 'x' (list (cons 410 (vla-get-name layout))))) was used but did not catch layouts where the viewport object has been deleted. vla-get-count will return 0 for non activated layouts and 1 for a layout with no objects.

Purge layer filters / delete layer filters in AutoCAD. You get it here at my blog or here.

or another approach because the above one is not working in newer versions of AutoCAD:

Using VBA where QnewPath is the Template File Name: ThisDrawing.Application.Preferences.Files.QNewTemplateFile = QnewPath
