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


If such elements exist in a sketch the [[Sketcher_Dialog#Solver_messages|Solver messages section of the Sketcher Dialog]] displays this message:
==Usage== <!--T:4-->
* Under constrained: <span style="color:blue;text-decoration:underline;">n DoF(s)</span>
Where ''n'' is the remaining number of degrees of freedom. Clicking the underlined text will select the under-constrained elements.

Description

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

If such elements exist in a 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 a 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.
