Sharing scenes across distinct models

[eneroth3]

Unfortunately signing in from within SketchUp very often fails (more often than it succeeds it seems).

These threads contain more info and work arounds for signing in:

Authentication error

Deleted all copies of SU 2015 and 2016, reloaded SU 2016 and got the the same “Authentication Error!” again this am. jrt

Unable to Sign-in to Extension Warehouse

Quit SketchUp Clear C:\Users\Your_User_Name\AppData\Roaming\SketchUp\SketchUp 2016\SketchUp\cookiejar.xml Open IE. Clear Cookies and cache data. Restart SketchUp, and click the login button lower left window (tool tip is “not logged in”). Login. If it fails, retry. If you get Authentication Error again, repeat steps 3-5
