Hi @Louis_Pienaar!
thank you for your student’s feedback. We’ve been working on improving on the points you mentioned with an update that will be available for you this month. The central axis rotation view will be replaced with more natural drag gestures which allows you to move the camera freely on the scene, unrestricted from the central axis rotation view.
To 1) the attaching feature could help your student in this case. You can find out more about grouping and attaching at the links below:
To 2.2): your students seem to have focussed on an item in the scene. This is done by double-tapping the item in the item-hierarchy on the left.
To 3) I’m sorry to hear that your students lost some of their work. It’s a very infuriating thing which we’re working on mitigating in our system. If your students see a red warning while they build, it means that the internet connection is not stable enough to save the student’s progress. It’s best to wait for the internet connectivity to recover and the warning to go away before building more.
