• If this function fails, the source shape is unchanged.
• See also SE_shape_add_island .
• If you pass a shape returned from SE_stable_search or SE_stable_get_shape to ‘shape’, the SE_READ_ONLY_SHAPE error is returned. See ‘Shape table functions’ for more information.
• If the source shape has a CAD entity, the SE_CAD_EXISTS error is returned.
