FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software application with finite element method (FEM) support. [2] It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical ...
3D rendering of a car in CAD software with boundary representation. Also important to the development of CAD was the development in the late 1980s and early 1990s of B-rep solid modeling kernels (engines for manipulating geometrically and topologically consistent 3D objects), Parasolid (ShapeData), and ACIS (Spatial Technology Inc.). These ...
A 3D CAD model. Computer-aided design ( CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design. [ 1]: 3 This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for ...

Abbreviations for "diameter" include ⌀, DIA, and D. For delta usage, see for example "delta notes". DIA[ 2] diameter.
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.
v. t. e. An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing. Usually, a number of drawings are necessary to completely specify even a simple component.
AutoCAD version history. AutoCAD is a commercial computer-aided design (CAD) and drafting software application by Autodesk. The first release of the software started with version 1.0 in December 1982. [ 1] The software has been continuously updated since its initial release. AutoCAD opens documents with DWG compatibility as a "DWG file format ...
