    **geometry\_transfer: bool, optional**: Option to enable transfer of geometry data (NURBS).
    
    **length\_unit: LengthUnit, optional**: Specify length unit for import.
    
    **refacet: bool, optional**: Refine or coarsen the CAD faceting based on refaceting parameters when true.
    
    **cad\_refaceting\_params: CadRefacetingParams, optional**: Specify refaceting parameters.
    
    **stitch\_tolerance: float, optional**: Stitch facets based on tolerance. Available only with WorkBench CAD Reader route.
    
    **cad\_update\_parameters: Dict\[str, Union\[str, int, float, bool\]\], optional**: Specify the CAD parameters for parametric CAD update. Available only with WorkBench CAD Reader route.
    
    **validate\_shared\_topology: bool, optional**: Specify whether to validate the shared topology information.
