MirrorManager

MirrorManager#

class MirrorManager[source]#

Bases: object

Manage mirror planes and mirrored draft entities inside a DraftContext.

This manager provides:

  • Storage/registration of MirrorPlane entities.

  • Creation/removal of mirror actions for GeometryBodyGroup entities.

  • Derivation and registration of draft-only entities: MirroredGeometryBodyGroup and (when possible) MirroredSurface.

Notes

Surface mirroring requires a surface-to-body-group mapping derived from GeometryEntityInfo. If that mapping cannot be derived (e.g. face grouping spans multiple body groups), mirroring is disabled and mirror operations will raise.

Properties

mirror_planes: EntityRegistryView#

Return all the available mirror planes.

Returns:

A registry view of MirrorPlane entities available in this draft.

Return type:

EntityRegistryView

Methods

create_mirror_of(*, entities, mirror_plane)[source]#

Create mirrored entities for one or more geometry body groups.

This registers mirror actions for the requested body groups and then derives/creates draft-only entities:

  • MirroredGeometryBodyGroup for each body group

  • MirroredSurface for each surface belonging to those body groups (when surface ownership mapping is available)

Newly created mirrored entities use MIRROR_SUFFIX ("_<mirror>") as a name suffix.

Parameters:

  • entities (list[GeometryBodyGroup] | GeometryBodyGroup) – One or more geometry body groups to mirror.

  • mirror_plane (MirrorPlane) – The mirror plane to use for mirroring.

Returns:

Mirrored geometry body groups and surfaces.

Return type:

tuple[list[MirroredGeometryBodyGroup], list[MirroredSurface]]

remove_mirror_of(*, entities)[source]#

Remove the mirror of the given entities.

Parameters:

entities (list[GeometryBodyGroup] | GeometryBodyGroup) – One or more geometry body groups to remove mirroring from.

Return type:

None
