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.
FreeCAD's own main file format is FreeCAD Standard file format (.FCStd). [9] It is a standard zip file that holds files in a certain structure. [ 9 ] The Document. xml file has all geometric and parametric objects definitions. [ 9 ]
G - BRL-CAD standard solid modeling open format including support for primitives, attributes, and arbitrary data storage; See also: Computer-aided design; CAD data exchange; Comparison of CAD, CAM and CAE file viewers; Electronic design automation
When CAD drawings became more popular, especially using US software, such as AutoCAD, the nearest font to this ISO standard font was Romantic Simplex (RomanS) - a proprietary shx font) with a manually adjusted width factor (override) to make it look as near to the ISO lettering for the drawing board.
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.
Building information model of a mechanical room developed from lidar data. Building information modeling (BIM) is an approach involving the generation and management of digital representations of the physical and functional characteristics of buildings or other physical assets and facilities.
An architectural drawing or architect's drawing is a technical drawing of a building (or building project) that falls within the definition of architecture.Architectural drawings are used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to assist a building ...
The file below shows three principal views and one that shows the true lengths in the plane of the roof. (The conic dormer shows parts of an ellipse and a hyperbola .) Descriptive geometry is the branch of geometry which allows the representation of three-dimensional objects in two dimensions by using a specific set of procedures.
