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.
RGB For red, green, and blue. A system of defining colors by specifying percentages of red,
green, and blue.
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.
rubber-band line A line that stretches dynamically on the screen with the movement of
the cursor. One endpoint of the line is attached to a point in your drawing, and the other
is attached to the moving cursor.
running object snap Setting an Object Snap mode so it continues for subsequent selections.
See also Object Snap mode and object snap override. (OSNAP)
sampling Sampling is an anti-aliasing technique. It provides a "best guess" color for each
rendered pixel. The renderer first samples the scene color at locations within the pixel or
along the pixel's edge, then uses a filter to combine the samples into a single pixel color.
scale representation The display of an annotative object based on the annotation scales
that the object supports. For example, if an annotative object supports two annotations
scales, it has two scale representations
script file A set of commands executed sequentially with a single SCRIPT command. Script
files are created outside the program using a text editor, saved in text format, and stored in
an external file with the file extension .scr.
secondary table fragment Any fragment of a broken table that does not contain the
beginning set of rows.
selection set One or more selected objects that a command can act upon at the same time.
