AutoCAD DXF (Drawing Interchange Format, or Drawing Exchange Format) is a computer-aided design (CAD) data file format developed by Autodesk [2] to enable CAD data exchange and interoperability between AutoCAD on different computing platforms.
Checkers, software that analyze CAD data formats, are often employed before and after data translation. The checkers can check the organization and quality of the data against internal company standards and international or industry standards. These checkers can be built into specific CAD packages or work on a number of CAD file formats.
Similarly, Siemens Digital Industries Software offers downloadable font sets for multiple languages such as for Asian character sets. The ISO 10303 STEP standards also handle a wide range of PMI information. ISO 10303 is an ISO standard for the computer-interpretable representation and exchange of product manufacturing information.
Coordinate dimensioning was the sole best option until the post-World War II era saw the development of geometric dimensioning and tolerancing (GD&T), which departs from the limitations of coordinate dimensioning (e.g., rectangular-only tolerance zones, tolerance stacking) to allow the most logical tolerancing of both geometry and dimensions ...
Model-based definition (MBD), sometimes called digital product definition (DPD), is the practice of using 3D models (such as solid models, 3D PMI and associated metadata) within 3D CAD software to define (provide specifications for) individual components and product assemblies.
Screenshot from AutoCAD showing usage of T.I.R., perpendicularity, and parallelism GD&T datum reference symbols.. An engineering datum used in geometric dimensioning and tolerancing is a feature on an object used to create a reference system for measurement. [1]
Example of true position geometric control defined by basic dimensions and datum features. 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.
The table below provides an overview of notable computer-aided design (CAD) software. It does not judge power, ease of use, or other user-experience aspects. The table does not include software that is still in development (beta software). For all-purpose 3D programs, see Comparison of 3D computer graphics software.
