AutoLISP was derived from an early version of XLISP, which was created by David Betz. [4] The language was introduced in AutoCAD Version 2.18 in January 1986, and continued to be enhanced in successive releases up to release 13 in February 1995.
AutoCAD supports a number of APIs for customization and automation. These include AutoLISP, Visual LISP, VBA, .NET and ObjectARX. ObjectARX is a C++ class library, which was also the base for: products extending AutoCAD functionality to specific fields; creating products such as AutoCAD Architecture, AutoCAD Electrical, AutoCAD Civil 3D
SolveSpace v3.0 is able to export 2D sketches and surfaces into DXF/DWG (AutoCAD version 2007), PDF, SVG, EPS, and HPGL file formats. Wireframes can be exported as DXF and STEP files. Polygon meshes can be exported as STL and Wavefront OBJ ; NURBS as STEP .
IIRC, in AutoLISP of AutoCAD 10, the form (lambda (x) (princ (b x))) returns the list ((x) (princ (b x))), which can then be called as a function. If you quote the whole thing, then the lambda symbol is left in the list; is the result still callable? I hope someone with recent AutoLISP experience can clarify these points.
One of its products, AutoCAD Data Extension, allowed multiple users to access the same AutoCAD drawing, or have a single drawing point to entities stored in other drawings. [ 11 ] In 1994, Softdesk, the then-largest third-party product developer for Autodesk , acquired IntelliCADD, and used the know-how to secretly develop an AutoCAD clone.
Release 2.1 of AutoCAD, released in 1986, included AutoLISP, a built-in Lisp programming language interpreter initially based on XLISP. [12] This opened the door for third party developers to extend AutoCAD's functionality, to address a wide range of vertical markets , strengthening AutoCAD's market penetration.
Lisp was originally implemented on the IBM 704 computer, in the late 1950s.. The popular explanation that CAR and CDR stand for "Contents of the Address Register" and "Contents of the Decrement Register" [1] does not quite match the IBM 704 architecture; the IBM 704 does not have a programmer-accessible address register and the three address modification registers are called "index registers ...
Open Design Alliance is a nonprofit organization creating software development kits (SDKs) for engineering applications. ODA offers interoperability tools for CAD, BIM, and Mechanical industries including .dwg, .dxf, .dgn, Autodesk Revit, Autodesk Navisworks, and .ifc files and additional tools for visualization, web development, 3D PDF publishing and modeling.
