The document discusses the functions and components of a CAD workstation. A CAD workstation must accomplish five key functions: interface with the central processing unit, generate a graphic image for the user, provide a digital description of the graphic image, translate computer commands into operations, and facilitate communication between the user and system. A typical CAD workstation consists of operator input devices and a graphics terminal to accomplish these functions interactively.
2. CAD WORKSTATION (DESIGN WORKSTATION )
? The CAD workstation is the system interface
with the outside world. It represents a
significant factor in determining how
convenient and efficient it is for a designer to
use the CAD system. The workstation must
accomplish five functions
3. WORKSTATION FUNCTIONS
? l. It must interface with the central processing
unit.
? 2. It must generate a steady graphic image for the
user.
? 3. It must provide digital descriptions of the
graphic image.
? 4. It must translate computer commands into
operating functions.
? 5. It must facilitate communication between the
user and the system
4. ? The use of interactive graphics has been found
to be the best approach to accomplish these
functions. A typical interactive graphics
workstation would consist of the following
hardware Components:
? Operator input devices
? A graphics terminal
