associative dimension A dimension that automatically adapts as the associated
geometry is modified. Controlled by the DIMASSOC system variable. See also
nonassociative dimension and exploded dimension.
associative hatch Hatching that conforms to its bounding objects such that
modifying the bounding objects automatically adjusts the hatch. (BHATCH)
associative surfaces Associative surfaces automatically adjust their location
and shape when the geometric objects associated with them are modified.
Controlled by the SURFACEASSOCIATIVITY system variable.
attenuation The diminishing of light intensity over distance.
attribute definition An object that is included in a block definition to store
alphanumeric data. Attribute values can be predefined or specified when the
block is inserted. Attribute data can be extracted from a drawing and inserted
into external files. (ATTDEF)
attribute extraction file A text file to which extracted attribute data is written.
The contents and format are determined by the attribute extraction template
file. See also attribute extraction template file.
attribute extraction template file A text file that determines which attributes
are extracted and how they are formatted when written to an attribute
extraction file. See also attribute extraction file.
attribute prompt The text string displayed when you insert a block with an
attribute whose value is undefined. See also attribute definition, attribute tag,
and attribute value.
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 for Mac library search path
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.
