||This task shows you how to create a Mirror Part, from an
Engineering or a Manufacturing Part,
in a separate or existing .CATPart document,
keeping the link to the original .CATPart.
This Mirror Part is created
copying and hiding the existing Composites features in a new CATPart,
adding symmetry features to the existing Composites features (only the
symmetry features are visible).
This action is to be used at the end of the
Engineering process or at the end of the Manufacturing process
(not in the
course of a designing process, to create a new part by symmetry from an
This Mirror Part keeps a link with the original part, so that it can be
synchronized with the original part, if it is modified.
- Do not regenerate a 3D Multisplice feature by editing the
feature and validating the edition with OK,
because this would
regenerate the cut-pieces and delete the Mirror features previously
created from the cut-pieces.
- Note that:
- Producibility parameters are transferred to the Mirror Part.
- the following elements are not generated in the Mirror Part:
- Core Samples,
- Numerical Analysis,
- Exploded surfaces
- Preliminary design entities (Composites PD): they are not
usable in the Mirror Part.
As in the manufacturing preparation document,
they are transferred if they are inputs of plies,
but in this case, the
Composites PD node cannot be extended.
However, Full plies
contour and ETBS features will be transferred (like
Other elements are transferred as follows:

- They are put in the No Show via their father

- A GSD symmetry feature is created in a new Geometrical Set
named Symmetry geometries,
- The name of the symmetry feature is Symmetry of Axis system.x,
- Each symmetry of Axis system is assigned to the corresponding stacking
(plies group, plies, cut-pieces, tape, core).
- The symmetry of the axis is created, with no orientation
- If you want to use another rosette, you must create it and
change the orientations of the plies manually.
- They are transferred as is so that the Mirror Part points to the same
and uses the same directions.
- The mirrored Stacking elements keeps a link with the original
- This link is visible using the Edit>Links... command,
- You cannot replace this link but you can deactivate it,
- It is visible through Enovia for Impacted by and
- Each ply geometry receives a new symmetry feature, named Mirror,
placed after all the composites features (contour, limit contour, skin swapping,
coming from the original part,
- This Mirror feature is similar to the symmetry features above,
the difference that it lays the result of the symmetry on the symmetry
of the reference surface.
- It can be edited.
||The ply direction remains the same, as the direction is expressed
in the symmetry of the original rosette.
- Associative cut-pieces (i.e. with Limit Contour features):
- No symmetry feature is added to the Composites Geometry of the
father ply (here Ply.10),
- A Mirror feature is added at the end of the Composites Geometry of

- Non associative cut-pieces (i.e. with datum curves as input to the

- A Mirror feature is added at the end of each cut-piece Composites
- Associative flatten geometry for plies and cut-pieces:
- Producibility paramaters are modified: a GSD symmetry feature is
created for the Seed point,
the seed curve and each curve of order of
If the Seed point was given by Point indication, a symmetry is
applied to the stored Point indication.
- The Flatten Rosette and the Flatten Contour are updated as they are
computed from the Ply Geometry,
hence from the new symmetry feature in

cut-piece or tape.
