vector A mathematical object with precise direction and length but without specific location.
vertex A location where edges or polyline segments meet.
view A graphical representation of a model from a specific location (viewpoint) in space.
See also viewpoint and viewport. (3DORBIT, VPOINT, DVIEW, VIEW)
view category A named collection of views in a sheet set that is often organized by function.
See also subset.
ViewCube User interface element that displays the current orientation of a model, and
allows you to interactively rotate the current view or restore a preset view.
viewpoint The location in 3D model space from which you are viewing a model. See also
view and viewport. (3DORBIT, DVIEW, VPOINT)
viewport A bounded area that displays some portion of the model space of a drawing. The
TILEMODE system variable determines the type of viewport created. 1. When TILEMODE
is off (0), viewports are objects that can be moved and resized on a layout. (MVIEW) 2.
When TILEMODE is on (1), the entire drawing area is divided into non-overlapping model
viewports. See also TILEMODE, view, and viewpoint. (VPORTS)
viewport configuration A named collection of model viewports that can be saved and
restored. (VPORTS)
virtual screen display The area in which the program can pan and zoom without
regenerating the drawing.
visual style A collection of settings that control the display of edges and shading in a
viewport.
volumetric shadows A photorealistically rendered volume of space cast by the shadow of
an object.
watertight A closed 3D solid or mesh that has no gaps.
WCS See world coordinate system (WCS).
window selection A rectangular area specified in the drawing area to select multiple objects
at the same time. See also crossing selection, polygon window selection.
wipeout object A polygonal area that masks underlying objects with the current background
color. This area is bounded by the wipeout frame, which you can turn on for editing and
turn off for printing.
wireframe model The representation of an object using lines and curves to represent its
boundaries.
