ToolBar / Extensions

Hi Sketchup Pros…I was trying to learn through a youtube tutorial, and the tutor went to the top toiolbar and clicked next to the “WINDOW” selection, there was one called “extensions”. Perhaps it was an older vwersion of SU (mine is 2016.So needless to say, I hit the proverbial wall and it stopped me dead (again). Here is a screenshot of a lions head that I brought in from autocad (DXF)…I was trying to make it a 3d model…but I’m suck…

The Extensions Menu only shows up if you’ve installed any extensions. It looks like you haven’t done that so there’s no need for the menu.
