Sketcher ConstrainSymmetric/de

Description
The symmetrical constraint constrains two selected points to be symmetrical around a given line, i.e., both selected points are constrained to lie on a normal to the line through both points and are constrained to be equidistant from the line. Alternatively it can constrain two points to be symmetric with respect to a third one.

How to use


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 the SymmetricalConstraint icon in the Sketcher toolbar 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.



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.
