Descripción
Descripción
La Restricción de Simetría restringe dos puntos seleccionados a ser simétricos con respecto a un eje dado. Los dos puntos seleccionados se restringen para situarse sobre la perpendicular al eje de simetría y situados a la misma distancia de este.
Funcionamiento
Selecciona dos puntos y una línea en el croquis. Los puntos y la línea seleccionados se volverán de color verde oscuro.
Pulsa sobre el icono
en la barra de herramientas del Croquizador o selecciona la Restricción de Simetría en el submenú de Restricciones del entorno del Croquizador (o del entorno de Diseño de Piezas).
Esto aplicará la restricción a los elementos seleccionados.
Esta es una restricción geométrica y no tiene parámetros editables.

- Make sure there is no selection.
- There are several ways to invoke the tool:
- Press the
Symmetric Constraint button.
- Select the Sketch → Constraints →
Symmetric Constraint option from the menu.
- introduced in 1.0: Right-click in the 3D View and select the Constrain →
Symmetric Constraint option from the context menu.
- Use the keyboard shortcut: S.
- The cursor changes to a cross with the tool icon.
- 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).
- A constraint is added.
- Optionally keep creating constraints.
- To finish, right-click or press Esc, or start another geometry or constraint creation tool.
Run-once mode
- 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).
- Invoke the tool as described above, or with one of the following additional options:
- introduced in 1.0: Right-click in the 3D View and select the
Symmetric Constraint option from the context menu.
- Right-click in the Elements section of the Sketcher Dialog and select the
Symmetric Constraint option from the context menu.
- A constraint is added.
Notes
- The arrows of this constraint have the same color as dimensional constraints.
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.
