GNU LibreDWG is a software library programmed in C to manage DWG computer files, native proprietary format of computer-aided design software AutoCAD. It aims to be a free software replacement for the OpenDWG libraries. The project is managed by the Free Software Foundation (FSF).
DesignSpark Mechanical is based on the SpaceClaim Engineer application and is the product of a collaboration between RS Group plc and Ansys, Inc. An introductory brochure is available here . The goal to offer a free 3D CAD software with many features of high-end software is to engage with those such as engineering education students or small ...
AutoCAD is a 2D and 3D computer-aided design (CAD) software application developed by Autodesk. [1] It was first released in December 1982 for the CP/M and IBM PC platforms as a desktop app running on microcomputers with internal graphics controllers . [ 2 ]
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 ...
DWG (from drawing) is a proprietary [3] binary file format used for storing two- and three- dimensional design data and metadata.It is the native format for several CAD packages including DraftSight, AutoCAD, ZWCAD, IntelliCAD (and its variants), Caddie and Open Design Alliance compliant applications.
As AutoCAD has become more powerful, supporting more complex object types, DXF has become less useful. Certain object types, including ACIS solids and regions, are not documented. Other object types, including AutoCAD 2006's dynamic blocks, and all of the objects specific to the vertical market versions of AutoCAD, are partially documented, but ...
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 ...
View of a CAD model of a four-cylinder inline crankshaft with pistons. A 3D CAD system (such as KeyCreator, Autodesk Inventor, or SolidWorks) first produces the geometry of the part; the technical drawing comes from user defined views of that geometry. Any orthographic, projected or sectioned view is created by the software.
