Glossary of Terms
Glossary is usually defined as an alphabetical list of technical terms in some specialized field of knowledge. This knowledge base glossary provides a collection of knowledge base documents that define many technical terms. These terms are arranged alphabetically, but you can quickly jump to a specific term by selecting its first letter from the index of the knowledge base glossary below.

radial copy
Also Duplicate Array (Vectorworks). An editing command which creates multiple copies of objects by copying them around a centerpoint for a given angle.
real scale
Objects in a CAD program a drawn at full scale or 1:1.
redraw
The process by which the video display is updated cleaning up any unwanted marks or construction points.
reference points
Points associated with drawing objects which allow an object to be selected, grouped, and manipulated. Reference points are often not visible. One example is the reference point of a text line which is often found at the lower left hand corner of the text line. To select a text entity it is often neccessary to click near this invisible point or include it within a selection window.
regenerate
The process by which the view updated from the drawing database cleaning up any unwanted marks or construction points. Similar but more comprehensive and time consuming that a redraw. Note: on some CAD packages these processes are synonymous.
relative coordinates
Drawing coordinates which when manually entered are interpreted as relative to the last point entered. In AutoCAD relative coordinates are entered by preceeding the coordinate pair with the @ sign such as @2,3.
resolution
The clarity or degree to which individual elements can be discerned on a monitor or print/plot. Common monitor resolutions include 600x800 and 1280x1024 measured in pixels. Common laser printer and plotter resolutions range from 300x300 to 600x600 dots per inch. Resolution of these devices determines how accurate a printout will be or how accurate an object will appear on the screen. The actual resolution of objects saved in the drawing database is usually much higher to insure a high degree of accuracy. When drawing objects are viewed on screen or plotted their size and position is rounded to the nearest dot at the resolution of a given device.
rotate
A drawing editing tool which rotates objects or groups of objects based on a center of rotation and an angle.
rubberbanding
A feature of many CAD programs which shows how a line or other object will look before it is actually placed. An example is with the line command. A starting point is selected after which a line appears rubberbanded between the first point and the cursor. As soon as another point is selected the actual line is drawn and the rubberband moves to the next point.
