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. In addition, DWG is supported non-natively ...
FreeCAD uses open-source libraries from the field of computing science; among them are Open CASCADE Technology [ 3 ][ 4 ] (a CAD kernel), Coin3D (an incarnation of Open Inventor), the Qt GUI framework, and Python, a popular scripting language. FreeCAD itself can also be used as a library by other programs.
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 ...
Appearance. Engineering drawing abbreviations and symbols are used to communicate and detail the characteristics of an engineering drawing. This list includes abbreviations common to the vocabulary of people who work with engineering drawings in the manufacture and inspection of parts and assemblies. Technical standards exist to provide ...
DWB – VariCAD drawing file; DWF – Autodesk's Web Design Format; AutoCAD & Revit can publish to this format; similar in concept to PDF files; Autodesk Design Review is the reader; DWG – Popular file format for Computer Aided Drafting applications, notably AutoCAD, Open Design Alliance applications, and Autodesk Inventor Drawing files
LibreCAD. LibreCAD is a computer-aided design (CAD) application for 2D design. It is free and open-source, and available for Unix / Linux, macOS, and Windows operating systems. Most of the interface and handle concepts are analogous to AutoCAD, making it easier to use for users with experience in this type of commercial CAD application.
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.
Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof. GD&T is used to define the nominal (theoretically perfect ...
