PDF AutoSave saves the copy of the Autodesk® Inventor® drawing automatically to PDF during Save command. There are multiple options for file naming and save location.

Note! PDF AutoSave works only when drawing is saved after modification. So it does not make a PDF if drawing has not changed.

Note! There are different versions of the app for different Inventor versions.
