#### ModelingGroup.export\_ply\_geometries(filename, ply\_level='production\_ply', boundary=True, surface=True, offset\_type='middle\_offset', direction\_arrows=False, first\_direction=True, second\_direction=False, arrow\_length=1.0, arrow\_type='no\_arrow')

Exports the surface, boundary, and/or fiber directions of modeling, production, and analysis ply to .igs or .step file.

- **Parameters:**
    - filename: File path (Available extensions are `.iges`, `.igs`, `.step`, and `.stp`).
    - ply\_level: Defines which plies are exported: `modeling_ply_wise`, `production_ply_wise`, or `analysis_ply_wise`. Default is `production_ply_wise`.
    - boundary: Boolean whether to export the boundary (default: `True`).
    - surface: Boolean whether to export the ply surface (default: `True`).
    - offset\_type: Offset type. Available options: `no_offset`, `middle_offset` (default), `top_offset`, and `bottom_offset`.
    - direction\_arrows: Boolean whether to export the direction arrows. Default is `False`.
    - first\_direction: Boolean whether to export the first (main) material direction (default: `True`).
    - second\_direction: Boolean whether to export the second material direction (default: `False`).
    - arrow\_length: Length of the arrows (default: `1`).
    - arrow\_type: Defines the arrow type. Available options: `standard_arrow`, `no_arrow` (default), and `half_arrow`.
