AutoLISP is a dialect of the programming language Lisp built specifically for use with the full version of AutoCAD and its derivatives, which include AutoCAD Civil 3D, AutoCAD Map 3D, AutoCAD Architecture and AutoCAD Mechanical. [1] Neither the application programming interface (API) nor the interpreter to execute AutoLISP code is included in ...
A man using AutoCAD 2.6 to digitize a drawing of a school building. AutoCAD was derived from a program that began in 1977, and then released in 1979 [5] called Interact CAD, [6] [7] [8] also referred to in early Autodesk documents as MicroCAD, which was written prior to Autodesk's (then Marinchip Software Partners) formation by Autodesk cofounder Michael Riddle.
It has many of the features of Lisp Machine Lisp (a large Lisp dialect used to program Lisp Machines), but was designed to be efficiently implementable on any personal computer or workstation. Common Lisp is a general-purpose programming language and thus has a large language standard including many built-in data types, functions, macros and ...
List of Lisp-family programming languages. The programming language Lisp is the second-oldest high-level programming language with direct descendants and closely related dialects still in widespread use today. The language Fortran is older by one year. [1][2] Lisp, like Fortran, has changed a lot since its early days, and many dialects have ...
Logo (programming language) Symmetry around a point can be obtained using only a few instructions, allowing users to draw hypotrochoids like the one shown here. Logo is an educational programming language, designed in 1967 by Wally Feurzeig, Seymour Papert, and Cynthia Solomon. [1] Logo is not an acronym: the name was coined by Feurzeig while ...
Dialog Control Language. Dialog Control Language (DCL) is a high-level description language and interpreter within AutoCAD for creating simple graphical dialogs. AutoLISP extensions use it to interact with the user in the AutoCAD environment.
CAR and CDR. In computer programming, CAR (car) / kɑːr / ⓘ and CDR (cdr) (/ ˈkʌdər / ⓘ or / ˈkʊdər / ⓘ) are primitive operations on cons cells (or "non-atomic S-expressions ") introduced in the Lisp programming language. A cons cell is composed of two pointers; the car operation extracts the first pointer, and the cdr operation ...
IntelliCAD is a CAD editor and development platform with an Application Programming Interface API published by the IntelliCAD Technology Consortium ("ITC") through shared development. IntelliCAD emulates the basic interface and functions of AutoCAD, however, it is particularly able to incorporate and interchange freely between a wide variety of ...
