Export to 3D PDF Not Showing

[MSD1]

I'm using Inventor 2021 Professional and I don't have an option to export a part or assembly to a 3D pdf.  I used to have this, probably in 2020 but I just noticed its not available now.  Why is this?  Is there a way to turn it on?

Maybe check if the default template is there? 

The default location for the 3D PDF templates provided by Autodesk is C:\Users\Public\Documents\Autodesk\Inventor <release>\Templates\<language>. If you specify a different template location in your project file, copy the sample templates to that location.

Here is a post on working with 3D pdf, there might be some useful info in there.

By Default it seems 2021 and 2022 Inv. do not load the add-in, although "Load Automatically" is selected... not sure why.

Make sure the add-in is LOADED here:

That works!  Thank you.  Leave it to Autodesk.......
