In-Depth Information
Many people naively assume that an AutoCAD drawing is always contained in a single
DWG file, but that's often not the case. Each drawing file created in AutoCAD can contain
references to other kinds of files, the most important of which are described in Table
20-2. Thus, before you start exchanging drawings via e-mail or FTP, you need a proced-
ure for assembling the drawings with all their dependent files.
As you can see from Table 20-2, the consequences of not including a custom font aren't
that dire: The recipient will still see your text, but the font will be different. Of course,
the new font may look odd or cause text-spacing problems within the drawing. If, on the
other hand, you forget to send xrefs or raster graphics that are attached to your main
drawing, the objects contained on those attached files simply will be gone when the re-
cipient opens your drawing. Not good!
Table 20-2 doesn't exhaust the types of files that your DWG files might refer
to. Custom plotter settings (such as custom paper sizes) may reside in PC3 or
PMP files. If you use sheet sets, a DST file contains information about the sheet
structure. An FMP file controls some aspects of font mapping. Look up
sheet sets
and the
FONTALT
and
FONTMAP system variables
in the AutoCAD online help sys-
tem for detailed information.
