dial The area at the right end of the status bar where you view the absolute or relative coordinates of the pointer. The type of coordinates displayed in the dial changes automatically as you change the grid type: for instance, if you change from an isometric to a circular grid, the dial will shift from xyz to polar coordinates. diameter dimension A dimension that measures the diameter of an arc or circle. A diameter dimension consists of a line, a pair of terminators, and a dimension label. difference Subtracting the area of one polygon from another. dimension A drawing entity that shows a measurement in a standard format. In AutoSketch, dimensions are associative. That is, they update the measurement display automatically when you resize them or when you change the default units of measurement. dimension label The text string that accompanies a dimension. A dimension label can display text before and after the measured value of the dimension. dimension line The line or arc in a dimension that shows the range being measured. direct selection The process of selecting entities by clicking on them individually or by enclosing them in a region.

A AutoSketch drawing file contains information such as the list of layers and database fields, what parts of the drawing are visible, and so on. For each entity, the drawing file stores its geometry, a list of graphic properties, and a list of any fields that you have assigned to it. drawing origin The point in a drawing that serves as a location reference for all entities in the drawing. The x- and y-axes cross at the drawing origin. The coordinates of the drawing origin are 0,0. drawing scale The ratio between page (output) size and actual (world) size. In a drawing whose scale is 1:10, for example, an entity that is 3 inches long on scaled output represents a real world object that is 30 inches long. drawing window A document window that contains a AutoSketch drawing. dropper tool A tool used to extract the properties of an entity and make them current on the property bar. .DWF file format A compressed file format that is easy to publish and view on the Web. .DWG file format The binary drawing file format used by AutoCAD. .DXF (drawing interchange) file format An ASCII- or binary-based drawing file format developed by Autodesk, Inc. and widely supported by CAD programs.

Glossary
dial
The area at the right end of the status bar where you view the absolute or relative
coordinates of the pointer. The type of coordinates displayed in the dial changes
automatically as you change the grid type: for instance, if you change from an isomet-
ric to a circular grid, the dial will shift from xyz to polar coordinates.
diameter dimension
A dimension that measures the diameter of an arc or circle. A
diameter dimension consists of a line, a pair of terminators, and a dimension label.
difference
Subtracting the area of one polygon from another.
dimension
A drawing entity that shows a measurement in a standard format. In
AutoSketch, dimensions are
associative
. That is, they update the measurement display
automatically when you resize them or when you change the default units of
measurement.
dimension label
The text string that accompanies a dimension. A dimension label
can display text before and after the measured value of the dimension.
dimension line
The line or arc in a dimension that shows the range being measured.
direct selection
The process of selecting entities by clicking on them individually or
by enclosing them in a region.
See also
Selection Modifier and marquee.
direction keys
See
arrow keys.
divide
To break an entity in two at the point where it is intersected by a second
entity.
DLL (Dynamic Link Library)
A file that contains program code that can be used by
any Windows application.
double line
Parallel lines created when you click Line, Double on the Draw menu.
Double lines are frequently used to create walls in architectural drawings.
drawing file
A storage container for a drawing. A AutoSketch drawing file contains
information such as the list of layers and database fields, what parts of the drawing are
visible, and so on. For each entity, the drawing file stores its geometry, a list of graphic
properties, and a list of any fields that you have assigned to it.
drawing origin
The point in a drawing that serves as a location reference for all
entities in the drawing. The x- and y-axes cross at the drawing origin. The coordinates
of the drawing origin are 0,0.
drawing scale
The ratio between page (output) size and actual (world) size. In a
drawing whose scale is 1:10, for example, an entity that is 3 inches long on scaled out-
put represents a real world object that is 30 inches long.
drawing window
A document window that contains a AutoSketch drawing.
dropper tool
A tool used to extract the properties of an entity and make them
current on the property bar.
.DWF file format
A compressed file format that is easy to publish and view on the
Web.
.DWG file format
The binary drawing file format used by AutoCAD.
.DXF (drawing interchange) file format
An ASCII- or binary-based drawing file
format developed by Autodesk, Inc. and widely supported by CAD programs.
AutoSketch both imports and exports .DXF files.
