Can I share files with employees/customers who do not have a SketchUp subscription?

Trimble Connect Yes. With Trimble Connect, you can share individual files with anyone, even third parties who are not Trimble Connect users, simply by sending a link. However, third parties can only view and download shared files, not edit them in Trimble Connect.

SketchUp Viewer for Desktop and SketchUp Mobile Viewer ( Apple iOS | Android ) allow others to view the models you share with them, whether they have access to SketchUp or not. Both are available for free, but the AR capabilities require a subscription or an in-app purchase on mobile.
