Usage

1. Select sketch to be mirrored (typically by clicking on it in the tree view).
2. Click on Mirror sketch or choose Sketch → Mirror sketch from the top menu.
3. The resulting sketch is created as a separate new object.

What is use of symmetric constrain?

The Symmetry constraint command enables you to constrain two sets of entities in a 2D profile so that they are symmetric to each other with respect to a symmetry axis. The Symmetry constraint requires that the entities be input as 3 groups — First Group, Second Group and the Axis Line.

How do you use external geometry in Freecad?

How do you use symmetric Creo?

First make some sketch, for our ease make a rectangle then create a center line. After this select the symmetry constraint option. Now select the center line by clicking on it and then select the two points on rectangle, which are highlighted, to make them symmetrical about the center line.

What is shape binder FreeCAD?

Description. The PartDesign ShapeBinder tool creates a shape binder referencing geometry from a single parent object. A ShapeBinder is used inside a PartDesign Body to reference geometry outside the Body. Using external geometry directly in a Body is not allowed and will lead to out of scope errors.
