Table Of Contents
model space. A final layout of specific views and annotations of this model is
placed in paper space. See also paper space. (MSPACE)
model viewports A type of display that splits the drawing area into one or
more adjacent rectangular viewing areas. See also layout viewports, TILEMODE,
and viewport. (VPORTS)
multileader A leader object that creates annotations with multiple leader
lines.
named object Describes the various types of nongraphical information, such
as styles and definitions, stored with a drawing. Named objects include
linetypes, layers, dimension styles, text styles, block definitions, layouts, views,
and viewport configurations. Named objects are stored in definition (symbol)
tables.
named objects, dependent See dependent named objects (in xrefs).
named view A view saved for restoration later. (VIEW)
node An object snap specification to locate points, dimension definition
points, and dimension text origins.
non-associative dimension A dimension that does not automatically change
as the associated geometry is modified. Controlled by the DIMASSOC system
variable. See also associative dimension and exploded dimension.
normal A normal is a vector that defines which way a face is pointing. The
direction of the normal indicates the front, or outer surface of the face.
noun-verb selection Selecting an object first and then performing an operation
on it rather than entering a command first and then selecting the object.
NURBS For nonuniform rational B-spline curve. A B-spline curve or surface defined
by a series of weighted control points and one or more knot vectors. See also
B-spline curve.
NURBS surface Surfaces that are have control vertices in the U and V
directions. NURBS surfaces cannot be associative. See also procedural surface
and generic surface.
object One or more graphical elements, such as text, dimensions, lines, circles,
or polylines, treated as a single element for creation, manipulation, and
modification. Formerly called entity.
Object Snap mode Methods for selecting commonly needed points on an
object while you create or edit a drawing. See also running object snap and
object snap override.
