About the Mirror Representation

The Mirror Representation is created by copying and hiding the existing Composites features in a selected representation, and by adding symmetry features to the existing Composites features (only the symmetry features are visible).

Geometrical Features Describing the Stacking
The input elements of those geometrical features are:
  • Copied to the Mirror Representation
  • Hidden in their father geometrical set (only the mirrored elements are visible).

A Generative Shape Design symmetry feature named Symmetry of xxx is created under a new geometrical set named Symmetry geometries.

Rosette Features
  • Each Rosette feature is assigned to the corresponding stacking element.
  • The symmetry of the axis is created with no orientation changes.
  • If you want to use another rosette, you must create it and change the orientation of the plies manually.
  • For Rosette features: Each symmetry of a Rosette feature is assigned to the corresponding stacking element

References Surfaces Corresponding to Plies Groups, Plies, Cut-Pieces, ....
Each symmetry feature is assigned to the corresponding stacking element (plies groups, plies without cut-pieces, plies without cut-pieces, plies with no associative cut-pieces, cut-pieces, ...).

In the Mirror Representation, the symmetry is not applied to a ply with associative cut-pieces, but to its cut-pieces. As a consequence, the symmetry is not applied to the reference surface of the ply but the reference surface of the cut-pieces.

Note: When creating a core sampling on a ply with associative cut-pieces, select the Take cut-pieces into account check box.

Composites Parameters
They are transferred as is: The Mirror Representation points to the same material catalog and uses the same directions.
Stacking

Stacking(Engineering) and Stacking(Manufacturing) are transferred respectively to Stacking(Engineering mirrored) and Stacking(Manufacturing mirrored).

Link
The Mirror Representation keeps a link with the original representation, visible in Links & Relations.
Note: You cannot replace this link, but you can de-activate it.
Plies
A new symmetry feature named Mirror.x is created under Geometries.
Note: The Mirror Representation is created using the "as result" mechanism, meaning that all the contour features from the original part are gathered in the Mirror.x feature.

The Mirror.x feature is similar to those described above, with the difference that it lies on the symmetry of the reference surface.

The ply direction remains the same, as this direction is expressed in the symmetry of the original rosette.

Preliminary design entities (Composites PD)
They are not usable in the Mirror Representation:
  • They are transferred if they are inputs of plies, but in this case, the node Composites PD cannot be expanded.
  • Full plies contour and ETBS features are transferred.
Core Samples
They are not transferred.
Numerical Analyses
They are not transferred.
Exploded Surfaces
They are not transferred.
3D Multisplice
Do not regenerate a 3D Multisplice feature by editing the feature and validating the edition by OK. This would regenerate the cut-pieces and delete the mirrored features previously created from the cut-pieces.

Adding a 3D Multisplice feature to a ply makes synchronization impossible.

MultiSplice From Producibility features are not imported into the Mirror Representation.

Fiber Mesh Curves
  • The mirrored Fiber Mesh Curves features are gathered in the Reverse Symmetry Geometries geometrical set, enabling you to find the initial Fiber Mesh Curves features.
  • The mirrored Fiber Mesh Curves features are updated from new geometries of plies.
  • The mirrored Fiber Mesh Curves features are used to create cut-pieces in the Mirror Representation.

  • Fiber Mesh Curves features created by MultiSplice From Producibility features and used to create cut-pieces are also gathered in the Reverse Symmetry Geometries geometrical set, and isolated (not updated).

Producibility Parameters
They are transferred to the Mirror Representation.
