Material
This page is about the material data system in FreeCAD.
Abstract
Since its hard, or even impossible, to define a fixed or complete set of material properties, we go a more open way. Every object in FreeCAD which has to deal with material will have a Property named "Material" which is in itself a key/value list which can hold a infinite number of material properties. Since this is a very open and extensible way to deal with such data, its hold also the danger of chaos. There fore this page define some rules and basic properties to deal with such material-property-maps.
