Return CrossSection.

Parameters:

  • width – main Section width (um).

  • offset – main Section center offset (um).

  • layer – main section layer.

  • sections – list of Sections(width, offset, layer, ports).

  • port_names – for input and output (‘o1’, ‘o2’).

  • port_types – for input and output: electrical, optical, vertical_te …

  • bbox_layers – list of layers bounding boxes to extrude.

  • bbox_offsets – list of offset from bounding box edge.

  • cladding_layers – list of layers to extrude.

  • cladding_offsets – list of offset from main Section edge.

  • cladding_simplify – Optional Tolerance value for the simplification algorithm. All points that can be removed without changing the resulting. polygon by more than the value listed here will be removed.

  • radius – routing bend radius (um).

  • radius_min – min acceptable bend radius.

  • main_section_name – name of the main section. Defaults to _default
