About DWF Driver Custom Properties
You can use the DWF6 ePlot driver to plot or publish DWF files. You can open, view,
and print DWF files with a DWF file viewer. DWF files support real-time panning and
zooming as well as control over the display of layers and named views.
values for layers or objects, a default lineweight of .01 inches is applied to all
graphical objects when you plot a drawing. This can cause areas of your plotted DWF
files to look significantly different from how they appear in the drawing area when
viewed in an external viewer or Internet browser, particularly during zoom operations.
To avoid this, disable the Plot with Lineweights option when you plot the drawing.
