recorded value The input captured during the recording of an action macro for a sub-prompt
of a command.
rectangular break To break a table into multiple parts that are evenly spaced and set at a
user-specified height using the table breaking grips.
redraw To quickly refresh or clean up blip marks in the current viewport without updating
the drawing's database. See also regenerate. (REDRAW)
reference A definition, known as an external reference or block reference, that is used and
stored in the drawing. See also block (BLOCK) and external reference (xref). (XREF)
refine To quadruple the number of faces in a mesh object as you reset the baseline level of
smoothness. (You cannot make a mesh courser than its baseline level.) You can also refine
specified mesh faces without resetting the baseline level of smoothness for the object.
(MESHREFINE)
reflectance scale Increases or decreases the amount of energy the material reflects.
reflection color The color of a highlight on shiny material. Also called specular color.
reflection line In a dynamic block reference, the axis about which a flip action's selection
set flips when the associated parameter is edited through a grip or the Properties palette.
reflection mapping Creates the effect of a scene reflected on the surface of a shiny object.
refraction How light distorts through an object.
regenerate To update a drawing's screen display by recomputing the screen coordinates
from the database. See also redraw. (REGEN)
region Two-dimensional enclosed areas that have physical properties such as centroids or
centers of mass. You can create regions from objects that form closed loops. They area
commonly created in order to apply hatching and shading. (REGION)
relative coordinates Coordinates specified in relation to previous coordinates.
relax constraints Ability to temporarily ignore constraints while editing geometry. After
the geometry is edited, the constraints are either removed or retained based on whether the
constraint is still valid for the edited geometry.
request user input An item that is assigned to an action node that pauses the playback of
an action macro so a user can provide some form of input before playback resumes.
reverse lookup Adds a lookup grip to a dynamic block reference. When you click this grip,
a drop-down list of the lookup values for that lookup property (column in the lookup table)
is displayed. When you select a value from the list, the corresponding input property values
