[email protected] Collaborating with AutoCAD® and Autodesk DWF™ Composer Introduction AutoCAD can export (plot or publish) drawing files in a special format called Design Web Format (DWF). This capability was first introduced as an add-on to AutoCAD Release 14. Later releases incorporated this capability as a basic function of AutoCAD. The DWF file format has changed over the years. Initially, DWF files were 2D only and contained a single sheet. More recently, Autodesk introduced 3D DWF files and enabled DWF files to contain multiple sheets. Note: The majority of this class will deal with 2D DWF files, except as noted. While AutoCAD can export drawing files in DWF format, AutoCAD itself can’t read DWF files. But the Markup Set Manager introduced in AutoCAD 2005 can open DWF files inside AutoCAD. You should think of 2D DWF files as the electronic version of plot files: they contain an intelligent image of your drawing, not the drawing itself. DWF files can be opened, viewed, and printed by anyone using one of Autodesk’s DWF viewing products. Volo View and DWF Composer also add measure and markup capabilities. If you publish the DWF files to the Web, anyone can view those DWF files by using the free Autodesk DWF Viewer. DWF files offer several advantages over other methods of saving and viewing drawings on the Web: • Accurate: DWF files contain two-dimensional vector information. When you zoom in to increase the magnification, the image continues to display as vectors • Fast: The DWF format is highly compressed, so they are smaller and faster to transmit than DWG files. • Smart: The DWF format supports multisheet files, so you can publish an entire design set as a single DWF file. Plus, when you create hyperlinks in your drawing and then create a DWF file, those hyperlinks are included in the DWF file. • Safe: The DWF file does not expose the original AutoCAD DWF file. This means that you can publish your drawings to the Web in DWF format, while maintaining the ownership of the intellectual property contained in the DWG file You can publish a DWF file from any AutoCAD 2004 or newer product by using the PUBLISH command. You can also plot a DWF file from any AutoCAD 2002 product. You can publish a DWF file from Inventor. You can export a 2D or 3D DWF file from Revit. You can also use the free DWF Writer (print driver) to create a DWF file from any other Windows program. Any DWF file can be viewed using the free Autodesk DWF Viewer. But most significantly for today’s discussion, you can view, markup, and print DWF files, including “round-tripping” of markups and annotations, using Autodesk DWF Composer. Note that Autodesk previously also sold a product called Volo View, which enabled viewing, printing, and markup of DWF or DWG files. As of May 1, 2005, Volo View is no longer available for sale. 2 Collaborating with AutoCAD® and Autodesk DWF™ Composer Using Autodesk’s Viewers Autodesk has offered numerous viewers since originally introducing the DWF format. Older viewers have been discontinued. Autodesk now offers two products: DWF Composer and the DWF Viewer. The following chart outlines the major differences between these products: Feature DWF DWF Viewer Composer View 2D DWF™ files (including multisheet DWF 6) View 3D DWF Real-time pan and zoom Print/plot with same fidelity as AutoCAD View DWF markups Built-in measurement tools Add markups Revise DWF (add status stamps; add, delete, reorder sheets) Integrate markups with AutoCAD View AutoCAD® DWG files View Autodesk DXF™ files View raster image files View Autodesk Inventor® 7 (or higher) IPT, IAM, and IDW files Price/availability $199 FREE The DWF Viewer is only for viewing DWF files. It’s a small application and can be freely shared with others. It has a stand-alone interface for viewing DWF files, but also runs as an ActiveX application to view DWF content embedded in other applications, such as Internet Explorer, Word, Excel, and PowerPoint. In addition, when you include DWF content on a web page, you can configure the embedded DWF file so that if the system being used to view your page does not yet a DWF viewer installed, the DWF Viewer automatically downloads to the local machine. In some ways, DWF files are similar to PDF. Like DWF, PDF files can contain multiple sheets and can contain the same information that would otherwise appear in a plotted drawing. But the ability to create DWF files from AutoCAD is included free as part of AutoCAD. And the DWF file of an AutoCAD drawing will always be smaller than the same PDF file created from that drawing, approximately 1/20th the size of the original AutoCAD DWG file. What is Autodesk DWF Composer Autodesk DWF Composer is a computer program created by Autodesk to enable team members and clients to review and markup design information even if they do not own or know how to use sophisticated software such as AutoCAD. It supports the electronic exchange of drawings and markup among participants through the Internet, an intranet, or by using physical media such as disks. After review and markup in DWF Composer, drawings can be sent back to the original designer for response to markup. This exchange can continue until all issues are resolved, and the original designer revises the drawing. Once you have a drawing or sheet set in DWF format, you can: 3 Collaborating with AutoCAD® and Autodesk DWF™ Composer View • View a single drawing sheet or various sheets within a multisheet set • Open several instances of DWF composer to view sheets simultaneously • View 2D models, named views, and layouts • View flat 2D layouts created from 3D models • View 3D models saves as 3D DWF files • View the dimensions of a drawing • Follow hyperlinks within a set Turn layers on and off • View object properties in a drawing from Architectural Desktop • Navigate to various markups and keep track of the author, time of creation, current status, and team discussion notes Markup • Markup a drawing sheet with markup comments, text, drawings, dimensions, and stamps • Respond to markups • Change the status of markups • Measure 3D models • Save snapshots of 3D DWF files as 2D DWF files • Exchange discussion notes with others about a markup Republish • Reorganize and recombine different drawing sheets into a set • Save drawing sheets with their markups • Print drawings with or without markups • Distribute drawings for further review • Save drawings directly to Buzzsaw • Embed drawings on a web site • Return drawing sheets to the originating designer to be read in Autodesk DWF Viewer or DWF Composer, or if the original drawing came from the AutoCAD 2005 (or later) family of software or Revit, return the DWF there to be aligned with the original DWG drawing. Markups can then be responded to and returned to you. Understanding What Gets Written to a DWF File A DWF file is truly an electronic version of a plot file. When you plot the DWF file, you specify settings such as paper size, rotation, scale, and pen assignments, just as you do when plotting to any other device. Only those layers that are visible, actually contain data, and set to plot are written to the DWF file. In addition, the DWF file contains all the linetype, lineweight, and color settings in effect when you plot the drawing to create the DWF file. Once the DWF file is created, you can use the tools contained in any of Autodesk’s DWF viewers to display a particular sheet, turn selected layers on and off, and pan and zoom to limit what is displayed, just as with an AutoCAD drawing. You can also snap to geometry in the DWF file just as you can in AutoCAD and take accurate measurements. Any hyperlinks contained in the original drawing are retained and active in the resulting DWF file. External references are also preserved. Including Raster Images in DWF Files Raster images are stored in the DWF file. Including Named Views in DWF Files Any named views that are saved in the DWG file when the DWF file is created are saved to the resulting DWF file and can be restored using any of Autodesk’s DWF viewers. For convenience, a view named INITIAL, if not already defined in the drawing file, is also saved as part of the DWF file.
