Hello,
i just found a maintained "Ready to run Script for Autodesk Fusion 360" in Github -> https://github.com/cryinkfly/Autodesk-Fusion-360-for-Linux
The Maintainer is very active and provide a full script including documentation. Thanks to cryinkfly's work, i was easy able to install Fusion 360 successfully under Manjaro!
Maybe there is a way to port the needed settings, packages and adjustments to Crossover ?
If not, yeah - just use the script :)
Cheers!
