#### *static* FuseParams.set\_default(use\_absolute\_tolerance=None, gap\_tolerance=None, side\_tolerance=None, check\_interior=None, fuse\_option=None, check\_orientation=None, dump\_mesh=None, local\_remesh=None, n\_layers=None, separate=None, angle=None, fuse\_edges\_only=None)

Set the default values of the `FuseParams` object.

- **Parameters:**
    
    **use\_absolute\_tolerance: bool, optional**: Option to use absolute tolerance value. The default value is false. When use absolute tolerance is true, gap tolerance and side tolerance provided are absolute values.
    
    **gap\_tolerance: float, optional**: Gap tolerance between faces to be fused. The default value is 0.05.
    
    **side\_tolerance: float, optional**: Side tolerance for fusing to the side edges.
    
    **check\_interior: bool, optional**: Option to check the interior nodes. The default value is false. When check interior is true, checks all nodes including boundary edge nodes and nodes inside the faces.
    
    **fuse\_option: FuseOption, optional**: Option for treatment of fused surfaces. The default value is None.
    
    **check\_orientation: bool, optional**: Option to check the face normal orientation during fuse operation. The default value is true. When check orientation is true, face normal orientation is checked during fuse operation.
    
    **dump\_mesh: bool, optional**: Option to save mesh for debugging. The default value is false. When dump mesh is true, mesh is saved for debugging.
    
    **local\_remesh: bool, optional**: Option to remesh the fused region. The default value is true. When local remesh is true, local remeshing of fuse region is performed.
    
    **n\_layers: int, optional**: Face layers around region to be fused. The default value is 2.
    
    **separate: bool, optional**: Option to separate fused regions. The default value is false. When separate is true, the fuse regions are separated into different zonelets.
    
    **angle: float, optional**: Faces zonelets with angle less than the provided value are considered for fuse operation. Default value is 45 degrees.
    
    **fuse\_edges\_only: bool, optional**: Option to fuse edges. The default value is false. When fuse edges only is true, only edges are fused.
