AutoCAD DXF

From Draftsperson.net

AutoCAD DXF (Drawing Interchange Format, or Drawing Exchange Format) is a CAD data file format, developed by Autodesk as their solution for enabling data interoperability between AutoCAD and other programs.

DXF was originally introduced in December 1982 as part of AutoCAD 1.0, and was intended to provide an exact representation of the data in the AutoCAD native file format, DWG (Drawing), for which Autodesk did not publish specifications. Autodesk currently publishes specifications on its website for versions of DXF dating from AutoCAD Release 13 (November 1994) to AutoCAD 2007 (March 2006.)

Versions of AutoCAD from Release 10 (October 1988) and up support both ASCII and binary forms of DXF. Earlier versions support only the ASCII form.

As AutoCAD has become more powerful, supporting more complex object types, DXF has become less useful. Certain object types, including ACIS solids and regions, are not documented. Other object types, including AutoCAD 2006's dynamic blocks, and all of the objects specific to the vertical-market versions of AutoCAD, are partially documented, but not at a sufficient level to allow other developers to support them.

Almost all significant commercial application software developers, including all of Autodesk's competitors, choose to support DWG as their primary format for AutoCAD data interoperability, using libraries from the Open Design Alliance - a non-profit industry consortium which has reverse-engineered the DWG file format.

ASCII versions of DXF it can be read with a text-editor.

E-book: AutoCAD Block Best Practices

We draw repetitively when using AutoCAD. If we manage the drawing elements as reusable contents, it will increase our productivity significantly. Not only can we draw faster, we can add information to our blocks. Which allows us to generate useful reports. This is what Edwins e-book entitled AutoCAD Block Best Practices is all about.
