Table Of Contents
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.
