Hi,
They only thing a student needs is a free sketchucation account and Sketchucation Tools v4.2.3
Download Sketchucation Tools here...
https://sketchucation.com/resources/plugin-store-download
...and install it into SketchUp. Login to their free account and install and extensions they want through our tool.
It also handles licensing so it is needed to help you manage your seats etc.
Then they can trial Fredo's tools for 30 days or purchase as needed. If any run into trouble they can email support[at]sketcucation.com
