Publishing and Printing with AutoCAD - Seventh 7

30.6 DWF and DWFx files

The creation of files in DWG format is necessary if other users are going to edit the drawing or develop new objects in it. However, in many cases, for example, once a project is finished, we must share the file with third parties, but not for its modification, but only for its knowledge or, perhaps, its approval. Even those third parties probably do not even have Autocad. For this and other cases, the Autodesk programmers developed the DWF (Design Web Format) format.
The DWF files and its most recent extension, the DWFx, in the first place, are much more compact than their DWG peers, their main function is to serve as a means of presenting the drawings and for their printing, so they can not be edited as DWG, nor contain all the detailed information of the objects.
However, DWF and DWFx files are not bitmaps, such as JPG or GIF images, but vector drawings, so the quality of the drawing remains constant even when we zoom in on them.
To view the DWF and DWFx files, without Autocad, you can download, and use, the Autodesk Design Review program for free, which will allow you to view the files, print them, publish them on the internet or, if it is a model 3D, navigate in them with zoom and orbit tools, as we will see in the drawing part 3D later.

But let's see how to create such files.

30.6.1 Creation

DWF files are also defined as electronic plotting files. That is, it is like seeing a plan already printed, but in bits, instead of paper. So its creation is equivalent to sending the file to print, just as we did with PDFs, only instead of using a printer or plotter, you have to choose one of the two electronic plotters (ePlot) that comes preconfigured with Autocad, the file “DWF6 ePlot.pc3” or “DWFx ePlot.pc3”. We can see these electronic plotters in the plotter configuration folder that we studied in section 30.1 of this chapter. Therefore, when ordering printing, it is enough to choose any of them as the plotter (or printer) to use. Another method is to use the export button on the Output tab. In either case, what follows is to write the name that the file will have.
