when the grid is turned on. Also called drawing limits. (LIMITS)
grip modes The editing capabilities activated when grips are displayed on an object:
stretching, moving, rotating, scaling, and mirroring.
grip tool An icon that you use in a 3D view to easily constrain the movement or rotation
of a selection set of objects to an axis or a plane. (3DMOVE, 3DROTATE)
grips Small squares and triangles that appear on objects you select. After selecting the grip,
you edit the object by dragging it with the pointing device instead of entering commands.

turned on. The ground plane displays with a color gradient between the ground horizon
(nearest to the horizon) and the ground origin (opposite the horizon). See also sky and
underground.
guide curves Lines or curves that intersect each cross section of a lofted solid or surface and
that define the form by adding additional wireframe information to the object. (LOFT)

on top of or over the drawing area without obscuring the view of the objects drawn on the
drawing area.
