Introduction
Eine Eigenschaft ist ein Stück Information wie eine Zahl oder eine Zeichenkette, das mit einem FreeCAD-Dokument oder einem Objekt eines Dokuments verbunden ist. Eigenschaften können mit dem Eigenschaftseditor angezeigt und geändert werden.

Eigenschaften spielen in FreeCAD eine sehr wichtige Rolle, da es konstruiert wurde, um mit parametrischen Objekten zu arbeiten, die nur durch ihre Eigenschaften definiert werden.

All property types
Benutzerdefinierte geskriptete Objekte in FreeCAD können Eigenschaften der folgenden Typen besitzen:

Internally, the property name is prefixed with :

Remember that these are property. A single object may have many properties of the same type, but with different names.

For example:

This indicates an object with three properties of type "Float", named "Length", "Width", and "Height", respectively.

Scripting
FreeCAD scripting basics

A scripted object is created first, and then properties are assigned.

In general, properties are assigned by using the object's  method. On the other hand, properties are normally provided automatically by the parent object from which the scripted object is derived.

For example:
 * Deriving from provides only 4  properties: "Display Mode", "On Top When Selected", "Show In Tree", and "Visibility".
 * Deriving from provides 17  properties: the previous four, plus "Angular Deflection", "Bounding Box", "Deviation", "Draw Style", "Lighting", "Line Color", "Line Width", "Point Color", "Point Size", "Selectable", "Selection Style", "Shape Color", and "Transparency".

Nevertheless, properties can also be assigned using the view provider object's  method.

Source code
In the source code, properties are located in various files.

They are imported and initialized in.
