By default, DWF files are produced with a vector grid of 1200 dots per inch
(DPI), which means the files have roughly the same precision and security
as paper.
Specify a DPI setting based on how small your objects are, relative to the
plot scale. The maximum number of virtual DWF dots allowed on a page
is 231 (2,147,483,647 in each dimension). To find the maximum allowed
DPI for your map, divide the maximum number of dots (231) by the
number of inches of the longest paper dimension. For example, for 42"x36"
paper, you can have a maximum DWF DPI of about 51 million
dots-per-inch. However, precision increases file size: a fifty-million-DPI
file is about twice the size of a 1200-DPI file (file size is not linear with
resolution). Set the DPI for DWF files using the DWF6 ePlot.PC3 settings.
See Set the DWF File Resolutionin the AutoCAD Help.
NOTE While it is safe to use very large DPI values for vectors, increasing
gradient or raster DPI increases your file size exponentially. This can cause
system failure.
■
Assign a coordinate system (page 142) to the map.
Make sure that the coordinate system is valid for the data in the map. For
example, a coordinate system for Canada might not support converting
x,y values to latitude and longitude for a map of Thailand.
■ Make sure that the graphics fall within the region of the coordinate system.

To prepare a map for publishing to DWF
1 Display and set up the layout you plan to use for your publishing job.
A layout is an AutoCAD paper space environment where you can specify
the size of your sheet, add a title block, display multiple views, and create
dimensions and notes for your map. For more information about creating
or editing a layout, see Create Multiple-View Drawing Layouts (Paper Space)
in the AutoCAD Help.
