C h a p t e r f o u r t e e n Using Drawings, Maps, and Layers
282
Layered Illustrator documents. As in InDesign, you choose a preset
for converting to PDF; unlike in InDesign, you don’t export the file but
simply choose the File > Save As command. The default Illustrator Adobe
PDF Preset includes exporting layers (
Figure 103c
).
Note
Since the AI format is a derivative of PDF, you are changing format char-
acteristics rather than converting to a different format type.

Flattening Layers
If you work with Visio
drawings that are converted
to PDF on a regular basis and
don’t need to preserve the
layers, select “Always flatten
layers and don’t show this
dialog again” in the second
panel of the PDFMaker
dialog. The default option
is to flatten the drawing;
choosing the “Always flatten
layers” option saves you one
step in your conversions.
