Connecting Solis With Blocs
The process of connecting Solis with Blocs is very simple. First open the Blocs application and make sure you have canvas broadcasting enabled in the main preferences.
Now open a project in Blocs and then navigate down to the bottom of right corner of the inspector sidebar. If Solis is installed on your Mac, Blocs will show a new icon in the window toolbar. Clicking this button will launch Solis.
