![]() ![]() Keys are changed which every release to keep files as small as possible. To read DWG files you therefor require the right key to understand the binary data. Data is very much compressed using a key. DWG files can be refered to as a kind of ZIP file. The text format of DXF is responsible for the difference in file size. The DWG (and DOC) is the original (binary) format while DXF (and RTF) mainly are text based exchange formats (with an open, documented structure). The difference between the DXF and DWG file format The difference between the DWG and DXF format are similar to the difference between MS Word DOC and RTF format. Despite this, files can be easily exchanged between users using earlier versions of for example AutoCAD. The current official file format AutoCAD 2012 DWG is the same DWG-file format as in AutoCAD 2010 and The AutoCAD DWG-format is also the same DWG-file format used in the latest versions of sector specific Autodesk products suchs as AutoCAD Architecture, AutoCAD Map 3D, AutoCAD Civil 3D, AutoCAD Electrical and AutoCAD Mechanical. The DWG format has become the standard for the exchange of CAD drawings. From 1982 until 2009, Autodesk released versions of AutoCAD resulting in 19 DWG file format variations of which no source is made public. History of the DWG file format DWG (recognisable by the.dwg file name extension) originates from the Interact CAD package, developed by Mike Riddle at the end of the 70ts and acquired by Autodesk in 1982 as starting point for AutoCAD. Our membership of the Open DWG Alliance ensures you of the fact that the latest DWG technology is included in the GEOiD software. See What do you need to know when using DXF and DWG file formats on page 6. Problems using DWG files may well occur also while exchanging data between Autodesk applications. Using the DWG file format in non-autodesk products may result in different sorts of problems because the DWG data structure is not entirely published. DWG file format Specific internal drawing format used in the Autodesk applications. some cases of text objects, symbols, hatchings, etc. Main disadvantage of the universal exchange format is that not all drawing information is properly saved in a DXF file, e.g. DXF file format Universal exchange format created to enable work with CAD data in applications other than the AutoCAD software. DWG (DraWinG) is a specific internal drawing format. Robijn Managing director GEOiD and Autodesk files General 3Ĥ Autodesk file formats The DXF and DWG file format Introduction DXF (Data Exchange Format) is a file format, meant for exchanging graphical information between different applications. It a subject to further development with the years of gained specialised knowledge and expertise.
