Autodesk AutoCAD Dateiformate DWG, DXF und DXB
DWG
Nach außen ist dieses Dateiformat durch den Dateinamenanhang .dwg, für ‚normale‘ Zeichnungsdateien gekennzeichnet. Das Kürzel steht für drawing (engl. für „Zeichnung“). Die Dokumentation der Dateistruktur ist nicht frei erhältlich.
DXF
Die DXF-Schnittstelle ist eine quelloffene Schnittstelle des Herstellers Autodesk und unterliegt keinem neutralen Normungsausschuss, die Dokumentation für DXF ist aber frei verfügbar. Sie ist ein in ASCII-Zeichen lesbares Abbild der binär abgespeicherten DWG.
DXB
Das DXB-Dateiformat (engl. ”’drawing exchange format, binary) ist eine binäre Form des DXF-Dateiformates. Es ist extrem kompakt, kann im Verhältnis zu DXF schnell gelesen und geschrieben werden, ist aber für den Programmierer wesentlich aufwendiger als die ASCII-Variante. DXB wird nur in wenigen, hauptsächlich zeitkritischen Anwendungsfällen verwendet.

Version 8.0 Identical to version 7.0 with the following exception: - SWD support for non-3.3V targets. Version 9.1 - New design based on STM32F205. Version 9.2 Identical to version 9.1 with the following exception: - Pin 1 (VTref) is used for measuring target reference voltage only. Buffers on J-Link side are no longer powered through this pin but via the J-Link internal voltage supplied via USB.
