+====== Headline ======
+This workshop will provide an introduction to using CAD to design items you can make using the laser cutter. The laser cutter needs an input file of some sort; these can be created using an art-oriented package such as Inkscape, or using a CAD package. Art oriented packages such as Inkscape are typically faster and easier, and usually have a nice user interface. What they don't offer is accuray, and for anything that will be assembled with something else, this accuray is key. This is where CAD comes in.
+There are a number of CAD packages you can use - the only requirement for any package is that it can export a .DXF file. This is a common CAD interchange format, and is supported by the vast majority of CAD or vector-based design packages.
+This course is based around [[http://www.freecadweb.org/|FreeCAD]]. FreeCAD is a free and open source 3D CAD package, still under development but already very powerful.
+If preferred, you can complete this workshop using an alternative CAD package, however all hints and keyboard shotcuts assume you're using FreeCAD and you will need a basic level of competence in your chosen package before starting.
+Alternative CAD programs which Hackla members have experience of are:
