Sketcher ToggleActiveConstraint

Description

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 ToggleActiveConstraint you can re-activate the old constraint immediately.

Usage

  1. Select an already placed constraint, then press ToggleActiveConstraint.
  2. Alternatively, got to the task panel, to the Constraints section, select the constraint, then open the context menu (right-click), and select Deactivate.
  3. To activate the constraint again, select it, and press ToggleActiveConstraint again.

Examples

*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.*

Scripting

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.

Example:

import FreeCAD as App

sketch = App.ActiveDocument.Sketch
sketch.toggleActive(3)
