2. .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 ...

3. Form-Z - Wikipedia

   en.wikipedia.org/wiki/Form-Z

   Form·Z allows design in 3D or in 2D, using numeric or interactive graphic input through either line or smooth shaded drawings ().Modeling features include Boolean solids to generate complex composite objects; the ability to create curved surfaces from splines, including NURBS and Bézier/Coons patches; mechanical and organic forms using the previous as well as metaforms, patches, subdivisions ...

4. 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]

   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 ...

6. Design Web Format - Wikipedia

   en.wikipedia.org/wiki/Design_Web_Format

   The format was originally referred to as the Drawing Web Format, since DWF files were generated by the Autodesk Internet Publishing Kit. As the format grew in use beyond just AutoCAD, it was renamed to Design Web Format. Although originally a 2D-only format, DWF has evolved to include 3D. Today DWF files are generated by all Autodesk products.

7. Multiview orthographic projection - Wikipedia

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

   A great deal of confusion has ensued in drafting rooms and engineering departments when drawings are transferred from one convention to another. 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.

8. Rapid prototyping - Wikipedia

   en.wikipedia.org/wiki/Rapid_prototyping

   CAD post-processors will approximate the application vendors' internal CAD geometric forms (e.g., B-splines) with a simplified mathematical form, which in turn is expressed in a specified data format which is a common feature in additive manufacturing: STL file format, a de facto standard for transferring solid geometric models to SFF machines.

9. AutoCAD - Wikipedia

   en.wikipedia.org/wiki/AutoCAD

   Drawing Standards File .dws: Using the CAD Standards feature of AutoCAD, a Drawing Standards File may be associated to any .dwg or .dwt file to enforce graphical standards. Drawing Interchange Format .dxf: The .dxf format is an ASCII representation of a .dwg file, and is used to transfer data between various applications. [34]
