All CAD systems consist of hardware in the form of data input, the central implementation units, data storage devices and equipment results (output). For data input equipment CAD systems have more than one piece of equipment as follows:
1. The keyboard, which is a hardware keyboard, that functions to enter data or write commands through
the command line in a CAD system.
2. Mouse, the pointing device. Several other tools are touchpad pointing device or track ball. This tool
will be very helpful if we use a lot of work, especially graphics mode using CAD systems. By using our
mouse will easily glide the mouse to draw a line in the CAD system and clicking rather than moving the
cursor with the mouse keyboard.Dinamakan because of its small and has a tail (cable to the computer)
3. Central Processing Unit (CPU) hardware That is actually doing all the calculations are done by
komputer.Bagian consists of Arithmethic And Logical Unit (ALU) which functions to perform
arithmetic and logic operations. Setting calculation, where the precedence portion and which part is
delayed by Controller Unit, as well as processing, retrieval and transmission of data
4. Plotter, ie hardware whose function is to print the image - the image produced by the CAD system
