opacity map Projection of opaque and transparent areas onto objects, creating
the effect of a solid surface with holes or gaps.
origin The point where coordinate axes intersect. For example, the origin of
a Cartesian coordinate system is where the X, Y, and Z axes meet at 0,0,0.
Ortho mode A setting that limits pointing device input to horizontal or
vertical (relative to the current snap angle and the user coordinate system).
See also snap angle and user coordinate system (UCS).
orthogonal Having perpendicular slopes or tangents at the point of
intersection.
output property A lookup property whose value is determined by input
properties (other parameter properties) through the use of a lookup table.
page setup A collection of plot device and other settings that affect the
appearance and format of the final output. These settings can be modified
and applied to other layouts.
pan To shift the view of a drawing without changing magnification. See also
zoom. (PAN)
paper space One of two primary spaces in which objects reside. Paper space
is used for creating a finished layout for printing or plotting, as opposed to
doing drafting or design work. You design your model using the Model tab.
See also model space and viewport. (PSPACE)
parameter In a dynamic block definition, defines custom properties for the
dynamic block by specifying positions, distances, and angles for geometry in
the block.
parameter set A tool on the Parameter Sets tab of the Block Authoring Palettes
window that adds one or more parameters and one or more associated actions
to the dynamic block definition.
parametric design Ability to establish relationships between objects, to drive
the size and orientation of geometry with model and user-defined parameters.
parametric drawing Feature in AutoCAD that assigns constraints to objects,
establishing the distance, location, and orientation of objects with respect to
other objects.
partial customization file Any CUI file that is not defined as the main CUI
file. You can load and unload partial CUI files as you need them during a
drawing session.
