Command/es

Un comando de FreeCAD es lo que se ejecuta cuando presiona un botón de la barra de herramientas o escribe un método abreviado de teclado. Puede ser una acción muy simple, como cambiar el nivel de zoom de la vista 3D o rotar el punto de vista, o un sistema complejo que abrirá cuadros de diálogo y esperará a que el usuario realice tareas específicas.

Cada comando de FreeCAD tiene un nombre único, que aparece en la página Category: Command_Reference. Los comandos se pueden iniciar mediante un botón de la barra de herramientas, un elemento del menú o desde una secuencia de comandos de Python o la consola de Python, ejecutando:

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...)
