Does no longer supported mean no longer available? Reason I ask is, I was trying out Cloth works and it says it depends on SketchUcation Tools version 4.0.0 or later. I'm guessing now its impossible to use or licence Cloth Works using Sketchup 2016, as I likely cant even run SketchUcation Tools version 4.0.0 or later anyway. Never mind then. Cheers for your help.

Clothworks has been updated to support v4.2.5.

SketchUcation supports as many SU versions as feasible. Maybe lobby SU devs to offer an LTS version of SketchUp for users that are not interested in yearly releases or subscriptions.
