   A 2D CAD drawing 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 ...

3. Caddie (CAD system) - Wikipedia

   en.wikipedia.org/wiki/Caddie_(CAD_system)

   Caddie is a mid-range computer-assisted draughting (CAD) software package for 2D and 3D design. It is used primarily by architects, but has tools for surveyors and mechanical, civil and construction engineers. It was initially designed as an electronic drawing board, using concepts and tools clearly related to a physical board. [2]

4. .dwg - Wikipedia

   en.wikipedia.org/wiki/.dwg

   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 ...

5. Autodesk Inventor - Wikipedia

   en.wikipedia.org/wiki/Autodesk_Inventor

   Inventor allows analyzing 2D and 3D CAD models by creating a virtual representation of the final product in order to validate the form, fit, and functioning before it is built. [ 2 ] Autodesk Inventor supports parametric , direct edit, freeform modeling part modeling, and assembly modeling.

6. AutoCAD - Wikipedia

   en.wikipedia.org/wiki/AutoCAD

   The primary file format for 2D and 3D drawing files created with AutoCAD is .dwg. While other third-party CAD software applications can create .dwg files, AutoCAD uniquely creates RealDWG files. [32] The drawing version code changes between AutoCAD releases. [33] Using AutoCAD, any .dwg file may be saved to a derivative format. These derivative ...

8. Multiview orthographic projection - Wikipedia

   en.wikipedia.org/wiki/Multiview_orthographic...

   On engineering drawings, the projection is denoted by an international symbol representing a truncated cone in either first-angle or third-angle projection, as shown by the diagram on the right. The 3D interpretation is a solid truncated cone, with the small end pointing toward the viewer. The front view is, therefore, two concentric circles.

9. CAD standards - Wikipedia
