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.
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.
