Autodesk.dwf.viewer discussion group member, Paul Mason (I wonder if he will sell no wine before its time? Actually that was Paul Masson.), observed that his 3D DWF files were coarsely faceted when using the 3DDWFPUBLISH command from AutoCAD 2006. Though I believed that VIEWRES might make an improvement, fellow Autodesk employee Nilanjan Bhattacharya was quick to point out that FACETRES does the trick. FACETRES adjusts the smoothness of shaded and rendered objects and objects with hidden lines removed. Valid values are from 0.01 to 10.0. The default value is 0.5. Try setting FACETRES to 8.0. As you can imagine, DWF files get a little larger as the faces get smoother:
Thanks Paul for the question. Thanks Nilanjan for the answer.
Providing design data in 3D form allows recipients to pan, zoom, rotate, look through, hide, pull apart, or cross section before printing. Applications that provide interactive 3D capabilities are just one of the ways DWF goes beyond the paper.
