Table Of Contents
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.
bulge magnitude The amount of curvature where two surfaces meet. This
only applies to surfaces that have G1 or G2 continuity.
bump map A map in which brightness values are translated into apparent
changes in the height of the surface of an object.
button menu The menu for a pointing device with multiple buttons. Each
button on the pointing device (except the pick button) can be defined in the
customization file (acad.cuix).
BYBLOCK A special object property used to specify that the object inherits
the color or linetype of any block containing it. See also BYLAYER.
BYLAYER A special object property used to specify that the object inherits
the color or linetype associated with its layer. See also BYBLOCK.
callout block A block used as symbol to reference another sheet. Callout
blocks have many industry-specific terms, such as reference tags, detail keys,
detail markers, and so on. See also label block.
camera Defines the current eye-level position in a 3D model. A camera has a
location XYZ coordinate, a target XYZ coordinate, and a field of view or lens
length, which determines the magnification or zoom factor.
camera target Defines the point you are viewing by specifying the coordinate
at the center of the view.
candela The SI unit of luminous intensity (perceived power emitted by a
light source in a particular direction) (Symbol: cd). Cd/Sr
category See view category.
cell The smallest available table selection.
cell boundary The four gridlines surrounding a table cell. An adjacent cell
selection can be surrounded with a cell boundary.
cell style A style that contains specific formatting for table cells.
chain actions In a dynamic block definition, a property of point, linear, polar,
XY, and rotation parameters. When set to Yes, a change in an action that
contains the parameter in the action's selection set triggers any actions
