Very difficult

Its nice that its 3D but it hard to navigate, back to front view button will be great (reset view)...
We only need a zoom an move to sides option why do I need to see a view from top corner of the room?!!
If people saying this app is good then u are far from being a professional, u would check set.a.light desktop software...
