frame An individual, static image in an animated sequence. See also motion
path.
freeze A setting that suppresses the display of objects on selected layers. Objects
on frozen layers are not displayed, regenerated, or plotted. Freezing layers
shortens regenerating time. See also thaw. (LAYER)
front faces Faces with their normals pointed outward.

general property Properties that are common between a selection of objects.
These include Color, Layer, Linetype, Linetype scale, Plot style, Lineweight,
Hyperlink, and Thickness.
generic surface A 3D surface object with no control vertices, history, or
analytic information. Generic surfaces cannot be associative and they are
created when associative analytic surfaces are separated or by using the BREP
command. See also procedural surface and NURBS surface.
geographic elevation The relative height along the specified up-direction
defined for a geographic marker.
geographic marker Visual representation of geographic location information.
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.
