So I am following this tutorial to extend the autodesk forge viewer. I have compelted all of the steps and no button is showing, I assume this is due to an error with the loading.
https://forge.autodesk.com/blog/extension-skeleton-toolbar-docking-panel
I have also tried this tutorial, with the same issue:
http://learnforge.autodesk.io/#/viewer/extensions/selection?id=conclusion
My issue is I am not getting an error, the extension just isn't showing... does anyone know why?
I'm assuming theres an error in either the viewer or the index.
Below is my code: (index & forge viewer)
