CAD tip # 6515:

AutoPDF can help in company document management - makes your design data available both for the members of your design team and non-CAD users.

The AutoPDF utility (reactor) can be downloaded from Download, see description in the accompanying documentation and the AutoPDF command.

From the AutoPDF.txt:

On every SAVE/QSAVE/END of your DWG drawing AutoPDF saves/publishes a copy of your drawing to a PDF file. Old version of the PDF file is rewritten with the updated copy. You can setup the target folder for your PDF file and optionally upload it to a FTP or iPROJECT server.
The AutoPDF command can be used to disable/re-enable the auto-publishing functionality (ON/OFF options).
The 'noQS' toggle sets whether the _QSAVE (Ctrl+S) command also publishes PDF or not.
The 'Folder' option sets the target folder/subfolder name.
The 'FolderType' suboption specifies how the 'Folder' name is used - the 'Absolute' setting just uses the 'Folder' name as the target, the default 'Drawing' option saves the PDF copy with the DWG file, 'Current' saves the DWF in the AutoCAD current (Start-In) folder.
The 'Layout' option specifies which layout is published. The default 'Current' means the current layout when the drawing was saved (= mostly Model), 'Model' means "always publish the Model tab". The 'Append' suboption will append layout name to PDF filename. The 'Scale' suboption will leave the plot scale to Default (instead of Fit to scale).
The 'Upload' option lets you automatically upload the published PDF to a FTP server or your iPROJECT server.
The option 'Now' performs the PDF publishing on demand (not on save) - even when the reactor is switched Off. You can e.g. call "AutoPDF Now" in your menu macros for final plotting.
The 'Status' option lists current AutoPDF settings.
