Answer 1

A few things to check here:

• onToolbarCreated is only effective when using Viewer v7 or later
• it'd only get called after the Autodesk.Viewing.TOOLBAR_CREATED_EVENT event is fired
• you can either add a breakpoint inside your function or print to the console in there to detect if and when it's called instead of printing it to the console in your load callback ...
