## ModelingGroup.reorder\_plies(source, target, option='after', reverse: bool = False)

Reorder the ply group. Take source plies and insert before/after target ply. If the ModelingGroup itself is specified as a target, then the modeling plies retain their original global ply number.

### Parameters

- source: List of plies to insert at new position.
- target: Position to insert plies. Valid options are modeling group and sequence entity.
- option: Where to insert: after (default), before, end (for SequenceEntity targets), or keep (for : ModelingGroup targets). 
    - after: Paste right after the target.
    - before: Paste right before the target.
    - end: Paste at the end of the ModelingGroup containing target.
    - keep: Keep the previous global\_ply\_nr (only works for move, and when target is a ModelingGroup).
- reverse: If True, reverse the order of imported plies.
