The terms computer-aided drafting (CAD) and computer-aided design and drafting (CADD) are also used. [2] Its use in designing electronic systems is known as electronic design automation (EDA). In mechanical design it is known as mechanical design automation (MDA), which includes the process of creating a technical drawing with the use of ...
Other 1980s major players in CAD/CAM included General Electric [4] and Parametric Technology Corporation; [5] the latter subsequently acquired Computervision, which had been acquired by Prime Computer. [5] CAD/CAM originated in the 1960s; [6] an IBM 360/44 was used to build via CNC [7] [8] the wings of an airplane. CAD (Computer-aided design ...
Initially, with 3D in the 1970s, CAD was typically limited to producing drawings similar to hand-drafted drawings. Advances in programming and computer hardware, [20] [21] most notably solid modeling in the 1980s, have allowed more versatile applications of computers in design activities.
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. [4] It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical ...
Software using computer-aided technologies (CAx) has been produced since the 1970s for a variety of computer platforms. This software may include applications for computer-aided design (CAD), computer-aided engineering (CAE), computer-aided manufacturing (CAM) and product data management (PDM).
In general, there are three phases in any computer-aided engineering task: Pre-processing – defining the model and environmental factors to be applied to it (typically a finite element model, but facet, voxel, and thin sheet methods are also used); Analysis solver (usually performed on high powered computers);
