Symmetrize Solid#

Functionality#

This node performs operation similar to “Symmetrize Mesh” node, but works with Solid objects instead of meshes. In general, the node cuts the Solid object in half by a plane, takes one half, mirrors it relative to the same plane, and fuses original part with the mirrored part.

Note: Unfortunately, due to specifics of how FreeCAD booleans work, in some cases this node can produce weird (or even empty) results when Merge mode is enabled.

Inputs#

This node has the following inputs:

  • Solid. The Solid object to be symmetrized. This input is mandatory.

  • Point. This input is available only when the Direction paramter is set to Custom. This defines the point on the plane which is used as a mirror. The default value is (0,0,0) (origin).

  • Normal. This input is available only when the Direction parameter is set to Custom. This defines the normal of the plane which is used as a mirror. The default value is (0,0,1) (Z axis).

Parameters#

This node has the following parameters:

  • Direction. Transformation direction. This defines which part of the Solid object which be taken and where it will be mirrored to. The following directions are available:

    • -X to +X

    • +X to -X

    • -Y to +Y

    • +Y to -Y

    • -Z to +Z

    • +Z to -Z

    • Custom. The mirroring plane will be defined by Point and Normal inputs. The node will take the half of space where negative direction of the normal points to, and mirror it into the part where the normal points to.

    The default direction is -X to +X.

  • Merge Solids. If checked, then mirrored parts of the solid will be merged with original parts into a single Solid object. Otherwise, two separate objects will be produced. Checked by default.

Outputs#

This node has the following outputs:

  • Solid. The resulting Solid objects.
