What is CAD?
An electronic tool that enables you to make quick and accurate drawings with the use of the computer.CAD is an acronym for:-Computer Aided Drafting-Computer Aided Design-Computer Aided Drafting and Design (CADD)
Capabilities of a CAD system
Flexibility of editing- ability to make quick alterations to a drawing
Units and Accuracy levels- ability to change and work with different units and create highly accurate drawings
Storage and Access for drawings- save space, quick access, more organized
Capabilities (continued)Sharing CADD drawings- electronic files can be transferred easily and quickly from any location
Design- Allows you to quickly change current designs with accuracy
Main functions of all CAD systems
Draw- add geometry to drawing (lines, arcs, circles, ellipses, text)
Edit- change elements of drawings (erase, move, array, copy, offset)
Data Output- view/display functions, printing (zoom, pan, scale, colors)
Functions (continued)
System Control-Setting drawing environment (layers, line types, styles, drawing space, drawing aids)
Data Storage and Management-Filing, Saving drawings (open, saving, copying, deleting files)
