fit points Locations that a B-spline must pass through exactly or within a fit
tolerance. See also interpolation points and approximation points.
fit tolerance The setting for the maximum distance that a B-spline can pass
for each of the fit points that define it.
floating panel
A ribbon panel that is not attached to the rest of the ribbon or file window.
floating viewports See layout viewports.
font A character set, made up of letters, numbers, punctuation marks, and
symbols of a distinctive proportion and design.
footcandle The American unit of illuminance (symbol: fc). Lm/ft^2.

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)
general property Properties that are common between a selection of objects.
These include Color, Layer, Linetype, Linetype scale, Plot style, Lineweight,
Hyperlink, and Thickness.
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.
graphics area See drawing area.
graphics window See AutoCAD LT window and 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.
