Document Type: Part (also works with Part inside Product or Process)

Mirrors every hybrid shape inside a selected geometric set about a plane using a CATIA Symmetry operation, recreating the full geometric set structure in the current in-work object and preserving the original names of all shapes and geometric sets. Recurses through all child geometric sets automatically. Results are left as live parametric features with a link to the source geometry.

1. Open a CATPart document containing a geometric set and a plane or axis system
2. Run the script
3. Selection 1: Select the geometric set to mirror
4. Selection 2: Select a plane, axis system, or face of an axis system to define the mirror plane
5. The mirrored structure is created inside the current in-work geometric set

A child geometric set named after the source is created inside the in-work object, containing the full recreated structure with all shapes mirrored as live parametric features:

[in-work object]
 └── SourceSetName
 ├── Shape_A
 ├── Shape_B
 └── ChildSetName
 ├── Shape_C
 └── Shape_D

• All results are live parametric features — they retain a link to the source geometry and can be edited
• The source geometric set is not modified
• The selected geometric set must not be the current in-work object — the script will exit with an error if this is the case
• Use this script when you need to keep the parametric history; use Mirror Keep Name And Structure when you want isolated datums instead
• For mirroring individual selected shapes rather than a whole set use Mirror Keep History
