Übersicht
Der Eigenschafteneditor ist eines der wichtigsten Werkzeuge von FreeCAD und das Hauptelement bei der Arbeit mit FreeCAD. Mit dem Eigenschafteneditor werden die Eigenschaften der Objekte innerhalb des FreeCAD-Dokuments bearbeitet.

Generell ist der Eigenschafteneditor dazu gedacht, ein Objekt zu einer Zeit zu behandeln. Die im Eigenschafteneditor angezeigten Werte gehören zum aktiven Objekt des aktiven Dokuments (Vorsicht ist geboten, welches Dokument gerade aktiv ist, wenn mit mehreren Dokumenten gearbeitet wird). Wenn kein Element ausgewählt wurde (oder es keine gibt), bleibt der Eigenschafteneditor leer.

Nicht alle Eigenschaften können zu jeder Zeit geändert werden. Abhängig vom momentanen Zustand werden einige Eigenschaft als nur-lesen (read-only) angezeigt.

Die Eigenschaften eines Objekts werden in Ansicht- und Daten-Eigenschaften gruppiert und in unterschiedlichen Reitern angezeigt.

Verschiedene Objekte können unterschiedliche Eigenschaften haben. Trotzdem gibt es einige gemeinsame Eigenschaften bei allen Objekten, z.B. sind die Position und die Drehung (rotation) Daten-Eigenschaften eines Objekts, die geändert werden können.

Property definition
A property is a piece of information like a number or a text string that is attached to a FreeCAD document or an object in a document. Properties can be viewed and modified with the Property editor.

Properties play a very important part in FreeCAD, since it has been designed to work with parametric objects, which are objects defined only by their properties.

Custom scripted objects in FreeCAD can have properties of the following types:

Properties
There are two types of feature properties accessible through tabs at the bottom of the property editor:
 * : properties related to the "visual" display of an object.
 * : properties related to the "physical" parameters of an object.

View



 * : Indicates if a box showing the overall extent of the object is to be displayed. Value False, or True (Default, False).
 * : Indicates if the feature control points are to be displayed. Value False, or True (Default, False).
 * : Sets the accuracy of the polygonal representation of the model in the 3d view (tessellation). Lower values = better quality. The value is in percent of object's size (deviation in mm = (w+h+d)/3*valueInPercent/100, where w,h,d are the bounding box dimensions).
 * :Display mode of the feature, Flat lines, Shaded, Wireframe, Points [[IMAGE:Vue_DisplayModePartDesign_fr_00.png|96px]]. (Default, Flat lines).
 * : Lighting One side, Two side [[IMAGE:Vue_Lighting_fr_00.png|96px]]. (Default, Two side).
 * : Gives the color of the line (edges) (Default, 25, 25, 25).
 * : Gives the thickness of the line (edges) (Default, 2).
 * : Gives the color of the points (ends of the feature) (Default, 25, 25, 25).
 * : Gives the size of the points (Default, 2).
 * : Allows selection of the feature. Value False, ou True (Default, True).
 * : Give the color shape (default, 204, 204, 204).
 * : Sets the degree of transparency in the feature of 0 to 100 (Default, 0).
 * : Determines the visibility of the feature (like the bar ). Value False, or True (Default, True).

Data


Every feature has a placement that can be controlled through the Data Properties table. It controls the placement of the part with respect to the coordinate system. NOTE: The placement properties do not affect the physical dimensions of the feature, but merely its position in space! If you select the title Placement, a button with appears to the right. Clicking this button, opens the Tasks_Placement options window.

An angle is set here, and the axis that the angle acts upon is set with the axis property. The feature is rotated by the specified angle, about the specified axis. A usage example might be if you created a revolution feature as required, but then needed to rotate the whole feature by some amount, in order to allow it to line-up with another pre-existing feature.

The exact value of rotation comes from the angle property (above). This property takes three arguments, which are passed as numbers in the x, y, and z boxes in the tool. Setting a value for more than one of the axes will cause the part to be rotated in each axis, by the angle value multiplied by the value for the axis. For example, with an angle of 15° set, specifying a value of 1.0 for x, and 2.0 for y will cause the finished part to be rotated 15° in the x-axis AND 30° in the y-axis.

This takes three arguments, which are passed as numbers to the x, y, and z boxes in the tool. Setting a value for more than one of the boxes will cause the part to be translated by the number of units along the corresponding axis.



PS: The displayed properties can vary, depending on the tool used.
