.layer file Layer definition file. In AutoCAD Map 3D, a file that saves all of the
information required to recreate a layer, that is, the references to the source
data and the styles that have been applied to it.
adjacent sheet block An
annotation (page 2055) block used to indicate adjacent
tiles.
anchor point The location on a drawing object that determines the position
of any annotation attached to that object.
annotation A way to display related values on a drawing object. To annotate
geospatial features, use a
label (page 2066).
annotation definitions Specially created
blocks (page 2056) containing attributes
with Map
expression (page 2062) assigned to the attribute properties. Used with
drawing data.
annotation template The information to display in an annotation and the
layout of that information. Annotation templates are stored as specially named
blocks within your drawing. They can include text and graphics.
as-built Data that depicts the final installed configuration (physical or
functional). As-built data incorporates any field markups on the original
construction drawings.
as-designed Data that depicts the original plan for construction or installation,
for example, the design for a new electric service or a new pipe installation.
aspect Direction of ground slope.
attributes or attribute data Tabular data that describes the characteristics of
feature (page 2063) or drawing objects (page 2061), for example, the number of
lanes and pavement-type belonging to a road. For features, attributes can be
stored with the geometry, or stored in a database and joined to feature data.
For drawing objects, attributes are stored in a database and linked to selected
drawing objects. See also
property (page 2071), external data (page 2062) and object
data
(page 2070).
