Descrizione

Il vincolo Simmetria forza due punti selezionati ad essere simmetrici rispetto ad una data linea. Entrambi i punti selezionati sono vincolati a giacere sulla normale alla linea di simmetria attraverso gli stessi due punti e sono vincolati equidistanti dalla linea.

Utilizzo

See also: Drawing aids.

Continue mode

  1. Make sure there is no selection.
  2. There are several ways to invoke the tool:
    • Press the Constrain symmetric button.
    • Select the Sketch → Sketcher constraints → Constrain symmetric option from the menu.
    • introduced in version 1.0: Right-click in the 3D view and select the Constrain → Constrain symmetric option from the context menu.
    • Use the keyboard shortcut: S.
  3. The cursor changes to a cross with the tool icon.
  4. Do one of the following:
    • Select two points and a symmetry point (in that order).
    • Select two points and a symmetry line (idem).
    • Select a point, a symmetry line and another point (idem).
    • Select a line and a symmetry point (idem).
  5. A constraint is added.
  6. Optionally keep creating constraints.
  7. To finish, right-click or press Esc, or start another geometry or constraint creation tool.

Run-once mode

  1. Do one of the following:
    • Select two points and a symmetry point (in that order).
    • Select two points and a symmetry line (in any order).
    • Select a line and a symmetry point (idem).
  2. Invoke the tool as explained above, or with the following additional option:
  3. A constraint is added.

Scripting

Two points and a symmetry line:

Sketch.addConstraint(Sketcher.Constraint('Symmetric', Line1, PointOfLine1, Line2, PointOfLine2, SymmetryLine))

Two points and a symmetry point:

Sketch.addConstraint(Sketcher.Constraint('Symmetric', Line1, PointOfLine1, Line2, PointOfLine2, LineS, PointOfLineS))

A line and a symmetry point (In the GUI one can select a line and a point, but it uses internally the same form as above, with the two extremities of the same line):

Sketch.addConstraint(Sketcher.Constraint('Symmetric', Line, 1, Line, 2, LineS, PointOfLineS))

The Sketcher scripting page explains the values which can be used for Line1, Line2, LineS, Line, PointOfLine1, PointOfLine2 and PointOfLineS, and contains further examples on how to create constraints from Python scripts.
