I just tried the Squish command after downloading the latest service release and received the following dialog:
Unable to load Squish.rhp plug-in.
This plug-in is designed to run in the latest Rhino 6 Service Release.
Please download the latest service release from http://www.rhino3d.com/srUnknown command: Squish
When I tried the link I was directed to a 404 page.
I was using the command without issue yesterday: thoughts?
