3D documents can be scaled similarly. The only difference is that there is no handle. The user can simply tap and drag anywhere on the visible mesh to scale the object.
=== Tasks ===
POIs can, besides documents, also have tasks as children. You can view the list of available tasks (if any) by using the "Show Tasks" command. Similar to documents, a list of task previews will be shown. From there, you can place the tasks anywhere in the world, where they can be edited.
