u
vertical product
Any Autodesk software product, such as
AutoCAD Architecture and AutoCAD Civil
3D, that includes AutoCAD before its name.
Each of these products includes all the tools
found inside AutoCAD and expands on its
feature set by adding a number of industry-
specific tools and commands.
uCS
See User Coordinate System .
uCS icon
The double-arrow icon in the lower-left cor-
ner of the drawing area that indicates the
positive directions of the x- and y-axes for the
current User Coordinate System . In three-
dimensional views, the z-axis is also repre-
sented in the icon.
view
A picture of the current drawing from a par-
ticular user-defined perspective that is dis-
played on the screen or in a viewport . Views
can be named, saved, and restored.
user Coordinate System (uCS)
A definition for the orientation of the x-,
y-, and z-axes in space relative to three-
dimensional objects in the drawing or to
the World Coordinate System . UCSs can be
named, saved, and restored.
ViewCube
A navigation device used to switch between
standard, isometric, and freeform views in a
three-dimensional environment.
viewport
user-defined pattern
An opening, usually rectangular but not
always, through which the user can view
a drawing or a portion of it. There are two
kinds of viewports: tiled viewports (used in
model space ) and floating viewports (used in
layouts). See also layout .
Custom hatch pattern defined using the
Properties panel within the contextual Hatch
Creation Ribbon tab.
V
visual style
vector image
Any of ten variations of settings that
control the appearance of three-dimen-
sional objects to a viewer: 2D Wireframe,
Conceptual, 3D Hidden, Realistic, Shaded,
Shaded with Wireframe, Shades of Gray,
Sketchy, 3D Wireframe, or X-Ray. Found on
the View panel of the Ribbon when using the
3D Modeling or 3D Basics workspace.
A graphic that is stored using geometric
primitives, such as lines and arcs, which are
each based on a mathematical position and
length. Because a line is stored as a true line,
with both a start and end point, no degrada-
tion occurs when vector images are scaled up
or down.
