Command/de

Ein FreeCAD-Befehl ist das, was ausgeführt wird, wenn Du einen Symbolleisten-Button oder ein Tastenkürzel drückst. Es kann eine sehr einfache Aktion sein, wie den Zoomfaktor in der 3D-Ansicht ändern oder den Standpunkt zu drehen, oder ein komplexes System, das Dialogfenster öffnet und darauf wartet, dass der Benutzer bestimmte Aufgaben ausführt.

Each FreeCAD command has a unique name, that appears in the Category:Command_Reference page. Commands can be launched by a toolbar button, a menu item, or from a python script or the python console, by running:

FreeCADGui.runCommand("my_Command_Name")

FreeCAD commands are defined per workbench. Workbenches will normally add their command definitions at FreeCAD init time, so the command exists and is available as soon as FreeCAD is started, no matter if the corresponding workbench has been activated yet or not. In some cases, however, the workbench author might have decided, to not overload too much the FreeCAD startup process, to load the command definitions only at workbench init. In those cases, the command will only be available after the workbench has been activated (you have switched to it at least once with the workbench selector).

As most of them require user interaction, FreeCAD commands are only available in GUI-mode, and not in console mode. However, for convenience, most FreeCAD commands will either have a corresponding python function (like Part.makeBox or Draft.makeLine), or will execute code that is very easy to replicate in a python script.

Commands can be defined either in C++ or in Python.

Example of a C++ command definition (usually defined in /Mod/ModuleName/Gui/Command.cpp):

and a similar command in python (no rule for where it must be done, each python workbench does as it sees fit...)
