The Expand button 
displays an extension of the Export
dialog that shows additional
conversion parameters. This
displays the Advanced dialog. The Advanced
dialog for Export Modeling and
Export Drafting is different;
Drafting can be exported to the following file types: PFM,
IGES, DXF and
DWG.
This dialog extension contains two tabs:
General: which displays general file conversion parameters.
Parameters: which displays file conversion parameters that are specific to the file type being converted.
For explanations of parameters in the Advanced dialog, see the appropriate file type dialog (for example IGES Export, SAT Export, etc.).
Notes:
To
define default conversion settings (such as to automatically open the exported
documents at the end of export operations), use the Data
Interface Preferences.
Press the 
button (on the top right corner of the Export dialog) as a short cut to the
Preferences Editor and navigate
to General
/ Data Interface.
Press the Save
Settings button 
to create customized parameter sets.
This saves time by allowing you to predefine and save parameter values
for certain import or export operations, and then enabling you to "recall"
these parameter values by selecting the appropriate setting.
Pressing the Expand button displays the
additional parameters and also toggles the Expand button to the Collapse button 
. Press the Collapse button to hide the additional parameters.
