The following limitations apply to Box Move when moving or modifying solid objects.
The object being box moved must be a manifold object. Manifold geometry is physically realizable. A simple cube, for example, is manifold since you can physically create it. Two cubes sharing exactly one edge are non-manifold, since they are not physically realizable.
Box Move will modify bodies in a transverse manner, but not in rotation. Box Move will not work on the base of a cone because the sides of the cone need to be ’r;rotated’ in order to move to the new position. This is also the reason why Box Move will only change an object normal to the surface being moved.
Box Move will not work where there are multiple solutions. An example of this is a sphere that has been subtracted from the corner of a cube. Trying to Box Move the sphere face will not work.
