AutoLISP is a small, dynamically scoped, dynamically typed Lisp language dialect with garbage collection, immutable list structure, and settable symbols, lacking in such regular Lisp features as macro system, records definition facilities, arrays, functions with variable number of arguments or let bindings.
Contains the data that apply to nongraphical objects, used by AutoLISP, and ObjectARX applications. THUMBNAILIMAGE section Contains the preview image for the DXF file. END OF FILE. The data format of a DXF is called a "tagged data" format, which "means that each data element in the file is preceded by an integer number that is called a group code.
AutoCAD's native file formats are denoted either by a .dwg, .dwt, .dws, or .dxf filename extension. .dwg and, to a lesser extent, .dxf, have become de facto, if proprietary, standards for CAD data interoperability, particularly for 2D drawing exchange. [31] The primary file format for 2D and 3D drawing files created with AutoCAD is .dwg.
ObjectARX (AutoCAD Runtime eXtension) is an API for customizing and extending AutoCAD. The ObjectARX SDK is published by Autodesk and freely available under license from Autodesk. [ 1 ] The ObjectARX SDK consists primarily of C++ headers and libraries that can be used to build Windows DLLs that can be loaded into the AutoCAD process and ...
Python allows the creation of class methods and static methods via the use of the @classmethod and @staticmethod decorators. The first argument to a class method is the class object instead of the self-reference to the instance. A static method has no special first argument. Neither the instance, nor the class object is passed to a static method.
The 3D ACIS Modeler (ACIS) is a geometric modeling kernel developed by Spatial Corporation (formerly Spatial Technology), part of Dassault Systèmes.ACIS is used by software developers in industries such as computer-aided design, computer-aided manufacturing, computer-aided engineering, architecture, engineering and construction, coordinate-measuring machine, 3D animation, and shipbuilding.
Object-oriented programming uses objects, but not all of the associated techniques and structures are supported directly in languages that claim to support OOP. The features listed below are common among languages considered to be strongly class- and object-oriented (or multi-paradigm with OOP support), with notable exceptions mentioned.
Format is a function in Common Lisp that can produce formatted text using a format string similar to the print format string.It provides more functionality than print, allowing the user to output numbers in various formats (including, for instance: hex, binary, octal, roman numerals, and English), apply certain format specifiers only under certain conditions, iterate over data structures ...
