The [[Image:Sketcher_SelectElementsWithDoFs.svg|24px]] [[Sketcher_SelectElementsWithDoFs|Sketcher SelectElementsWithDoFs]] tool is meant to aid in fully constraining a sketch by highlighting in green the sketch elements with remaining degrees of freedom (DoF).

Description

The Sketcher SelectElementsWithDoFs tool selects the elements with remaining degrees of freedom (DoFs) in the sketch.

If such elements exist in the sketch the Solver messages section of the Sketcher Dialog displays this message:

  • Under constrained: n DoF(s)

Where n is the remaining number of degrees of freedom. Clicking the underlined text will select the under-constrained elements.

Please note that the sketch can also have under-constrained elements if one of these messages is displayed:

  • Redundant constraints: (#, #, #)
  • Over-constrained: (#, #, #)

Usage

  1. There are several ways to invoke the tool:
    • Click the underlined text in the Sketcher Dialog as described above.
    • Select the Sketch → Sketcher tools → Select unconstrained DoF option from the menu.
    • Use the keyboard shortcut: Z then F.
  2. The under-constrained sketch elements are selected.
  3. Optionally click in an empty area in the 3D view to clear the selection.
