Описание
ToggleActiveConstraint allows you to activate and deactivate an already placed constraint. This allows you to keep the constraint in the background but temporarily test another arrangement of the existing geometry.
The Toggle driving constraint tool is similar in that it disables the effect of the constraint; however, with this tool, the constraint does not keep its old value. On the other hand, with ToggleActiveConstraint you can re-activate the old constraint immediately.
Применение
- Select an already placed constraint, then press ToggleActiveConstraint.
- Alternatively, got to the task panel, to the Constraints section, select the constraint, then open the context menu (right-click), and select Deactivate.
- To activate the constraint again, select it, and press ToggleActiveConstraint again.
Примеры
Fully constrained sketch.
Left: deactivated constraint; the sketch is no longer fully constrained. Right: the unconstrained geometry can be moved around; the older constraint is still available, and can be re-activated to return to the fully constrained sketch.
Task panel with the deactivated constraint.
Программирование
See also: FreeCAD Scripting Basics.
The active status of a constraint can be controlled in macros and from the Python console.
SketchObject.toggleActive(index)
Use the toggleActive
method of an existing Sketcher SketchObject, and the index
of the constraint to activate it or deactivate it. The index starts from 0
all the way to N-1
, where N
is the total number of constraints.
Пример:
import FreeCAD as App
sketch = App.ActiveDocument.Sketch
sketch.toggleActive(3)
