‘Swift Prints’ has recently been updated for compatibility with Inventor 2018. In this update, the method to which your username to Autodesk 360 is obtained to validate your Swift Prints license has been changed. The retrieval of your username was also an issue with some users and resulted in Swift Prints not working properly. Autodesk recognized the issue and have provided a more robust means to do this in Inventor 2018.
You can download a 30 day trial of Swift Prints from the Autodesk App Store.
Swift Prints allows you to create templates for common printer configurations that you can quickly access later for one click printing of Autodesk® Inventor® drawings.
Also, Design Notes has been updated as well.
Design Notes is a history based note editor for all types of Autodesk® Inventor® files. Design Notes adds the ability to tag notes to a file without the overhead of maintaining another database.
