Descrizione
Questo strumento ha lo scopo di aiutare a vincolare completamente uno schizzo evidenziando in verde gli elementi dello schizzo con residui gradi di libertà (DoF).
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: (#, #, #)
Utilizzo
- There are several ways to invoke the tool:
- The under-constrained sketch elements are selected.
- Optionally click in an empty area in the 3D view to clear the selection.
