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 are assigned to the block reference.
Depending on how the block was defined, this usually results in a change in
the block reference's geometry. (BLOOKUPTABLE)
rewind Restores the previous view or movement path created by the Autodesk

ViewCube

navigation tool, SteeringWheels, and other navigation tools.
RGB For red, green, and blue. A system of defining colors by specifying
percentages of red, green, and blue.
ribbon A palette that displays buttons and controls used for both 2D drawing
and annotation and 3D modeling, viewing, and rendering. See also ribbon tab
and ribbon panel and slide-out panel. (RIBBON)
ribbon panel
A set of labeled controls, related to a task, grouped together in a ribbon.
Multiple ribbon panels, belonging to one workflow, are grouped together
under a ribbon tab.
ribbon tab
Highest level of ribbon grouping, based on an action. A ribbon tab contains
groups of multiple ribbon panels, each belonging to one workflow. A ribbon
panel contains buttons and controls, related to a task.
roll arrows Curved arrows located above the ViewCube tool with which you
can rotate the current view 90 degrees clockwise or counterclockwise.
roughness Value to simulate how light hitting a face is reflected back to the
user. A high roughness value simulates a non-shiny or rough object
(sandpaper/carpet). A low roughness value simulates a very shiny object
(metals, some plastics.)
row A horizontally adjacent table cell selection spanning the width of the
table. A single row is one cell in height.
