I don't know to open LightUp

I’m sure it’s very simple to begin to use but don’t know how to get in my tool bar. I downloaded and when i click on the download icon it just opens sketchup and then i don’t know what to do next. please help

Have you enabled the extension from the Preferences>Extensions window?

Anssi

you need to instal extensions from inside SU, not by clicking on the download…
