Table Of Contents
attribute tag A text string associated with an attribute that identifies a
particular attribute during extraction from the drawing database. See also
attribute definition, attribute prompt, and attribute value.
attribute value The alphanumeric information associated with an attribute
tag. See also attribute definition, attribute prompt, and attribute tag.
AutoCAD library search path The order in which looks for a support file:
current directory, drawing directory, directory specified in the support path,
and directory containing the executable file, acad.exe.
AutoCAD window The drawing area, its surrounding menus, and the
command line.
axis tripod Icon with X, Y, and Z coordinates that is used to visualize the
viewpoint (view direction) of a drawing without displaying the drawing.
(VPOINT)
B-spline curve A blended piecewise polynomial curve passing near a given
set of control points. See also Bezier curve. (SPLINE)
back face The opposite side of a front face. Back faces are not visible in a
rendered image. See also front faces.
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.
basic wheels A reference to the View Object wheel and Tour Building wheel.
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.
big wheels The large version of the SteeringWheels. Labels are displayed on
each wheel wedge and they are larger than the size of the cursor.
