Preview Query, Object Type drawing classification

Page 321 highlights

map query A set of conditions that specify the selection of drawing objects from source drawing (page 315)s. These conditions can be based on the location or properties of an object or on data stored in the drawing or in a linked database table. metadata Data about data. In the GIS context, metadata consists of information that describes the essential characteristics of geospatial data sets. Mpolygon A polygon object. A polygon differs from a closed polyline in that it stores information about its inner and outer boundaries. north arrow A visual indicator of the northern direction in a map. Sample north arrows and scale bars (both metric and imperial) are available as dynamic blocks for you to insert into your maps. object class All the drawing objects that have been created using a specific object class definition. Use object classification to organize objects in your drawing based on the real-world features they represent, such as roads. Object classes allow you to create new objects that automatically have the appropriate properties and values for objects in your drawing. object class definition How to create a classified drawing object in a drawing. An object class definition can include information about the object type, default properties of the object, or default data to attach to the object. object data The attribute data (page 309) attached to a drawing object and stored in the drawing file. Compare with external data (page 311). Object Type (drawing classification) A setting on the Applies To tab of the Define Object Classification dialog box that determines which existing objects you can add to this object class. If the object was not created with the selected method, you cannot add it. overlay analysis Provides spatial and data analysis capabilities for two sets of geospatial features. Use an Overlay operation to compare two layers that overlap in space. polygon A closed area that stores information about its inner and outer boundaries, and about other polygons nested in it or grouped with it. In a polygon topology, any lines or arcs in the drawing can enclose the polygon. In addition, AutoCAD Map 3D supports a polygon object, sometimes called an Mpolygon (page 313) or mapping polygon. Preview Query A query that displays the objects on screen, but does not retrieve them. When you change the screen, the objects disappear. property A single attribute of a feature class (page 311). A feature class has one or more property definitions. For example, you can have a Road feature class with properties called Name, NumberLanes, or Location.

map query
A set of conditions that specify the selection of drawing objects from
source
drawing
(page 315)
s. These conditions can be based on the location or properties of an object
or on data stored in the drawing or in a linked database table.
metadata
Data about data. In the GIS context, metadata consists of information that
describes the essential characteristics of geospatial data sets.
Mpolygon
A polygon object. A polygon differs from a closed polyline in that it stores
information about its inner and outer boundaries.
north arrow
A visual indicator of the northern direction in a map. Sample north arrows
and scale bars (both metric and imperial) are available as dynamic blocks for you to insert
into your maps.
object class
All the drawing objects that have been created using a specific object class
definition. Use object classification to organize objects in your drawing based on the
real-world features they represent, such as roads. Object classes allow you to create new
objects that automatically have the appropriate properties and values for objects in your
drawing.
object class definition
How to create a classified drawing object in a drawing. An object
class definition can include information about the object type, default properties of the
object, or default data to attach to the object.
object data
The
attribute data
(page 309)
attached to a drawing object and stored in the
drawing file. Compare with
external data
(page 311)
.
Object Type (drawing classification)
A setting on the Applies To tab of the Define Object
Classification dialog box that determines which existing objects you can add to this object
class. If the object was not created with the selected method, you cannot add it.
overlay analysis
Provides spatial and data analysis capabilities for two sets of geospatial
features. Use an Overlay operation to compare two layers that overlap in space.
polygon
A closed area that stores information about its inner and outer boundaries, and
about other polygons nested in it or grouped with it. In a polygon topology, any lines or
arcs in the drawing can enclose the polygon. In addition, AutoCAD Map 3D supports a
polygon object, sometimes called an
Mpolygon
(page 313)
or mapping polygon.
Preview Query
A query that displays the objects on screen, but does not retrieve them.
When you change the screen, the objects disappear.
property
A single attribute of a
feature class
(page 311)
. A feature class has one or more
property definitions. For example, you can have a Road feature class with properties called
Name, NumberLanes, or Location. See also
attribute data
(page 309)
,
feature
(page 311)
.
publish
To generate output from a map.
