Also as the rubber band you drop into your model lives inside it's own ldr, so you must make sure you are editing that model or use the nested editing mode from the top level model.
Nested editing will be the easier way as you keep your whole model in view. You go into nested editing mode by selecting its tab in the top right session label panel.
