geometric constraint Rules that define the geometric relationships of objects
(or points of objects) elements and control how an object can change shape
or size.
Geometric constraints are coincident, collinear, concentric, equal, fix,
horizontal, parallel, perpendicular, tangent, and vertical.
geometry All graphical objects such as lines, circles, arcs, polylines, and
dimensions. Nongraphical objects, such as linetypes, lineweights, text styles,
and layers are not considered geometry. See also named object.
gizmo A tool that permits you to manipulate a 3D object uniformly or along
a specified axis or plane. Examples of gizmos include the 3D Move, 3D Rotate,
and 3D Scale gizmos. They are displayed when you select a 3D object.
global illumination An indirect illumination technique that allows for effects
such as color bleeding. As light hits a colored object in the model, photons
bounce to adjacent objects and tint them with the color of the original object.
Gooch shading A type of shading that uses a transition from cool to warm
colors rather than from dark to light.
graphics area See drawing area.
grid An area covered with regularly spaced dots or lines to aid drawing. The
grid spacing is adjustable. The grid dots are never plotted. See also grid limits.
(GRID)
grid limits The user-defined rectangular boundary of the drawing area covered
by dots 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)
