I’m following a tutorial on Sketchup. There is reference to using the outliner. However when I go to the default tray I see
Entity Info, Materials, Components, Sytles, Shadows, and Instructor. However, there is not outliner.
Or you could do like I, and create a new custom tray (mine is named “TREE”,) and then add the Outliner panel to that. I have my TREE tray set to autohide into the left side margin, so it slides into view when I hover over it’s margin tab.
