Add a Centering Constraint

General

• For the centering constraint, three elements are required, of which the first two lines or points define the edges on which the last element (point) is centered.
• In sketch geometry, the symbol for the centering constraint is .
  • You can use the F9 key to show and hide the symbols of the constraints.

Add a centering constraint in plane sketch

1. Select the function Sketch | Constraints | Add centering constraint.
2. Select the first line or point.
3. Select the second line or point.
   • These lines or points remain in place unless the point to be centered is locked in place with constraints.
4. Select the point that you want to center.
   • This point will move so that it is in the middle of the selected lines or points.
   • However, if the point you want to centered is locked in place with constraints, the program moves one of the initially selected elements.
5. Repeat steps 2 to 4 to add new centering constraints
6. Stop adding centering constraints
