Hi,

It looks like your code is missing some elements. For example, I don't see where you load the FXML that defines your UI so the buttons won't appear. I would suggest trying to structure it more like the sample code.

With your current code if you call

sketchEditor.start()

after you have set the sketch editor on the view you can probably begin sketching but the buttons etc. won't work.
