DXF - This is not really an AutoCAD format but an industry standard, but one that you should be aware of. DXF stands for Drawing eXchange Format. This is a very standard format that is used but many different CAD and graphics programs. This allows users to exchange drawings even if they don't have the same program. When you use the DXF format, some objects may change their appearance when re-opened. As with DWG formats, DXF formats vary from different releases. You have the option of saving the files as a DXF or you can use the DXFOUT command, conversely DXF Files can be imported using the DXFIN command.
DXF represents "Drawing Exchange Format." It is a format for computer-aided design files, developed by Autodesk. The CAD program AutoCAD uses its own native file format, DWG; DXF is intended to be a sort of imitation of DWG.
For Microstation usersYou can use the saveas to get DWG/DXF from DGNYou can also use the "File --> export --> DGN, DWG, DXF" to get DXF filesFor AutoCAD usersCommand: DGNIMPORTAvailable in AutoCAD versions:AutoCAD MAPAutoCAD 2006~2010AutoCAD LT 2008~2010For other AutoCAD users and non-AutoCAD usersGet a plugin or look for stand alone converters to convert DGN to DXF.
Two methods: Open a DGN file in Misrostation V8 and.... # File --> Saveas --> Select format to save: AutoCAD drawing files (*.dwg) # File --> Export --> DGN, DWG, DXF --> Select format to save: AutoCAD drawing files (*.dwg)
GstarCAD MC is mainly designed for viewing drawings, it can read .dwg, .dxf and OCF files, but cannot save drawings. GstarCAD MC Pro can read .dwg, .dxf and OCF files; and it has a lot of extended functions for communicate and design on site.
DWG is file format for 2D and 3D design data, DWG in letters stands for "drawing". To open a DWG and view it, you need a DWG viewer. There are many DWG viewers online. The file format is designed by Autodesk. You can download free DWG viewer from Autodesk website. Or you can check with AIGraph CAD Viewer, a lightweight but powerful viewer
That depends entirely on who did the modelling...By and large the dwg and dxf files might be bette as they might be the original used for manufacturing but if you are going to view an object in a 3D viewer they might look just horrible while an obj or flt might look fine
GstarCAD can export: DWG, DWF, PDF, WMF, BMP, EMF, SVG and OCF file formats. You can also open and save DXF, JPEG, TIF, PNG, GIF file formats.
.dwg is the default drawing format of GstarCAD; at present, GstarCAD is compatible with ever version of .dwg and .dxf files from 2.5 to 2010, it is means GstarCAD is compatible from AutoCAD 2.5 to AutoCAD 2012. If you are using AutoCAD 2013, you have to exchange the file with GstarCAD and save it as earlier .dwg version before 2010. By the way, GstarCAD will be compatible with AutoCAD 2013 soon.
The file extensions are: .dwg .dxf .dwf .dng and many image files, like jpeg, gif, pdf, tiff, tga, .eps, and so forth. (As inserts)
DWG is file format for 2D and 3D design data, DWG in letters stands for "drawing". To open a DWG and view it, you need a DWG viewer. There are many DWG viewers online, and you can try AutoDWG DWGSee. You may open dwg file in classic manner with the help of Autocad program or if you have some troubles, make use tool below.
