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.
Select two points (vertexes) in the sketch and a line in the sketch. The selected points and the line will be dark green.
Click on Constrain symmetric or select the Constrain Symmetrical menu item from the Sketcher Constraints sub menu of the Sketcher (or Part Design) menu item.
This will apply the constraint to the selected items.
Note: Before Version 0.19 (see fix [1]), if you want to define a symmetry constraint with respect to a point, the order of the selection is important, depending on if you select the tool at the beginning or at the end.
- If you click the tool first: select the first point, then the symmetry reference point, and finally the second point.
- If you click the tool last: select the first point, then the second point, and finally the symmetry reference point.
See the tracker issue #4144, and forum thread.
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.
