The Problem
I have a pre Blocs 3.4 project that uses linked external assets and I would like to switch the project to use the embedded asset workflow, so that all assets are embedded within the Blocs project file.
The Solution
To embed all of the assets linked to a Blocs project, navigate to and select File > Project Assets > Embed All Assets In Project from the main window menu. This will trigger an automated function that will embed all of your projects linked external assets into the main Blocs project file, making it easy to transport Blocs projects between Macs.
