You can move, rotate, and scale individual
subobjects on 3D solids by clicking and dragging a subobjectâ€™s
grip, using grip tools (3DMOVE and 3DROTATE), or through commands
such as MOVE, ROTATE, and SCALE.

move, rotate or scale a subobject, the subobject is modified in a
way that maintains the integrity of the 3D solid. For example, when
you move an edge (in red in the following illustration), the faces
adjacent to the edge adjust so that the faces remain adjacent to
there are several possible results when you modify a solid. When
you move, rotate, or scale subobjects, you can press CTRL while you
drag to cycle through modification options. The illustration below
shows the modification options for moving a face (in red).

Rotate, and Scale Subobjects on Composite Solids
composite solidâ€™s History property is set to Record, you can only
select and move, rotate, and scale faces, edges, and vertices on
the individual primitives that make up the composite.
composite solidâ€™s History property is set to None, you can only

Limitations When Moving, Rotating, Scaling Subobjects
You can only
move, rotate, and scale subobjects on 3D solids if the operation
will maintain the integrity of the solid. The following rules and
limitations apply to moving, rotating, and scaling subobjects:
When you use grips to modify subobjects, grips are not
displayed on the subobjects that cannot be moved, rotated, or
In most cases, you can move, rotate, and scale both planar and
You can only modify an edge that is a straight line and that
has at least one planar adjacent face. The planes of the adjacent
planar faces are adjusted to contain the modified edge.
You cannot move, rotate, or scale edges (or their vertices)
that are imprinted inside faces.
You can only modify a vertex if it has at least one planar
adjacent face. The planes of the adjacent planar faces are adjusted
to contain the modified vertex.
When you drag a subobject, the final result may be different
than the preview displayed during the modification. This is because
the solid may have to adjust how itâ€™s been modified in order to
maintain its topology. In some cases, the modification may not be
possible because it may change the topology of the solid too
If the modification causes spline surfaces to extend, the
operation is usually unsuccessful.
You cannot move, rotate, or scale non-manifold edges (edges
that are shared by more than two faces) or non-manifold vertices.
Also, if some non-manifold edges or vertices are present near
faces, edges, and vertices that you modify, the operation may not
