Inventor Fusion mutates to Fusion360, a cloud based application, as it looks like. I've started using the beta of Fusion360. Descriptions of models created in Fusion360 appear in PLM360 - great. I'm on OSX wherever possible and do highly welcome the availability of Fusion360 for Mac.
I'd expect that PLM360 starts Fusion360 (if it's a Fusion file) when I click a link at the info of a part in the BOM of PLM360. I'm sure that there will be more cloud based apps and it should be standard, that a model or a design for which there is an entry in PLM360 can be opened directly from the PLM360 UI.
Privilege levels should be granted to memebers of the team - not everybody should be authorized to change.
