[https://en.wikipedia.org/wiki/Computer-aided_design &amp;#039;&amp;#039;&amp;#039;CAD&amp;#039;&amp;#039;&amp;#039;], or &amp;#039;&amp;#039;&amp;#039;Computer Aided Design&amp;#039;&amp;#039;&amp;#039; &amp;#039;&amp;#039;(and sometimes Computer Aided Drawing), involves the use of computers to produce the [https://en.wikipedia.org/wiki/Technical_drawing &amp;#039;&amp;#039;&amp;#039;Technical Drawings&amp;#039;&amp;#039;&amp;#039;] required to manufactrue products and which were once produced by [https://en.wikipedia.org/wiki/Drafter &amp;#039;&amp;#039;&amp;#039;Draftsmen&amp;#039;&amp;#039;&amp;#039;] working in [https://en.wikipedia.org/wiki/Design_studio &amp;#039;&amp;#039;&amp;#039;Drawing Offices&amp;#039;&amp;#039;&amp;#039;].&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Fully functioning CAD software has developed beyond just using computers to make drawings and can now also perform more complex tasks based on the drawing data &amp;#039;&amp;#039;(e.g. work out volumes, auto-route [https://en.wikipedia.org/wiki/Printed_circuit_board &amp;#039;&amp;#039;&amp;#039;pcb&amp;#039;s&amp;#039;&amp;#039;&amp;#039;] and calculate the degree of &amp;#039;&amp;#039;&amp;#039;[[Stress]]&amp;#039;&amp;#039;&amp;#039; experienced by components)&amp;#039;&amp;#039;. In addition to producing 2D drawings, some CAD software can also draw in 3D with abiity to rotate, show [https://en.wikipedia.org/wiki/Wire-frame_model &amp;#039;&amp;#039;&amp;#039;Wire-Frame&amp;#039;&amp;#039;&amp;#039;] and &amp;#039;&amp;#039;&amp;#039;X-Ray&amp;#039;&amp;#039;&amp;#039; versions of the component being designed.&lt;br /&gt;
&lt;br /&gt;
[[File:Sketchupexample.png|300px|right|Sketchupexample|http://www.sketchup.com/products/sketchup-make]]&lt;br /&gt;
Some CAD software is also [https://en.wikipedia.org/wiki/Parametric_design &amp;#039;&amp;#039;&amp;#039;Parametric&amp;#039;&amp;#039;&amp;#039;] which means that the drawn  model is linked in such a way that individual dimensions can be altered and the rest of the model changes to accommodate the change &amp;#039;&amp;#039;(i.e. a draw &amp;#039;&amp;#039;net&amp;#039;&amp;#039; in &amp;#039;&amp;#039;&amp;#039;[[/apps/menu/app?3&amp;amp;areas%2F2%2F1%2Fo%2F&amp;amp;0|Packaging Designer]]&amp;#039;&amp;#039;&amp;#039; can not only be scaled larger or smaller but its proportions altered to make it longer or thinner if need be)&amp;#039;&amp;#039;.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
There are some well established proprietary 2D software packages used in schools and various &amp;#039;&amp;#039;industry standard&amp;#039;&amp;#039; CAD programs. In addition there are free-to-use illustration packages &amp;#039;&amp;#039;(e.g. [https://en.wikipedia.org/wiki/SketchUp &amp;#039;&amp;#039;&amp;#039;Sketchup Make&amp;#039;&amp;#039;&amp;#039;])&amp;#039;&amp;#039; and free, [https://en.wikipedia.org/wiki/Open_source &amp;#039;&amp;#039;&amp;#039;Open Source&amp;#039;&amp;#039;&amp;#039;] fully functioning CAD applications &amp;#039;&amp;#039;(e.g. [http://freecadweb.org/ &amp;#039;&amp;#039;&amp;#039;FreeCAD&amp;#039;&amp;#039;&amp;#039;]).&lt;br /&gt;
