3D Transformations in 2D Groups
All objects have 3D transformations available, even when in 2D groups. All can be
rotated around any axis and moved along any axis. Keep in mind that objects in 2D
groups are not depth-sorted, and cannot intersect, regardless of their position in 3D
space.
Both of these groups are positioned at the same point in 3D space, but because they
are layer-ordered, group A does not intersect with group B. If you change the parent
group to 3D, the two groups will intersect.
Note: If two groups are coplanar (occupy the same plane), they are composited in
layer order, regardless of whether the objects’ parent is a 2D group or 3D group. In a
2D composite, all objects are coplanar.
