base point 1. In the context of editing grips, the grip that changes to a solid
color when selected to specify the focus of the subsequent editing operation.
2. A point for relative distance and angle when copying, moving, and rotating
objects. 3. The insertion base point of the current drawing. (BASE) 4. The
insertion base point for a block definition. (BLOCK)
baseline An imaginary line on which text characters appear to rest. Individual
characters can have descenders that drop below the baseline. See also baseline
dimension.
baseline dimension Multiple dimensions measured from the same baseline.
Also called parallel dimensions. See also baseline.
basic tooltip Displays a brief description for the tooltip.
Bezier curve A polynomial curve defined by a set of control points,
representing an equation of an order one less than the number of points being
considered. A Bezier curve is a special case of a B-spline curve. See also B-spline
curve.
bitmap The digital representation of an image having bits referenced to pixels.
In color graphics, a different value represents each red, green, and blue
component of a pixel.
blips Temporary screen markers displayed in the drawing area when you
specify a point or select objects. (BLIPMODE)
block A generic term for one or more objects that are combined to create a
single object. Commonly used for either block definition or block reference.
See also block definition and block reference. (BLOCK)
block definition The name, base point, and set of objects that are combined
and stored in the symbol table of a drawing. See also block and block reference.
block definition table The nongraphical data area of a drawing file that stores
block definitions. See also named object.
block instance See block reference.
block reference A compound object that is inserted in a drawing and displays
the data stored in a block definition. Also called instance. See also block and
block definition. (INSERT)
bounded area A closed area that consists of a single object (such as a circle)
or of multiple, coplanar objects that overlap. You can insert hatch fills within
bounded areas.
Bounded areas are also used to create 3D objects through extrusion by using
the PRESSPULL command.
