```cs
[Serializable]
public sealed class SectionStyle : ModelComponent
```

SectionStyle helps define the attributes to use when drawing a section

## Constructors

- [SectionStyle](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/ctor.md): (2 overloads) Create a new instance of a SectionStyle

## Properties

- [BackgroundFillColor](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/backgroundfillcolor.md): Fill color to apply to the background. Default is Color.Empty which means get the color from the source where this section style came from (object attributes or layer)
- [BackgroundFillMode](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/backgroundfillmode.md): How the background should be filled
- [BackgroundFillPrintColor](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/backgroundfillprintcolor.md): Fill print color to apply to the background. Default is Color.Empty which means get the color from the source where this section style came from (object attributes or layer)
- [BoundaryColor](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/boundarycolor.md): Color to apply for the boundary curves. Default is Color.Empty which means get the color from the source where this section style came from (object attributes or layer)
- [BoundaryLinetypeIndex](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/boundarylinetypeindex.md)
- [BoundaryPlotWeightMillimeters](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/boundaryplotweightmillimeters.md): Plot width of the boundary curves. values less than -1 (-10 is default): plot weight is determined by the object's attributes -1: do not plot 0: use default weight defined by the print dialog positive values are thicknesses in millimeters to print to NOTE: if a linetype is assigned to this section style that has a physical width (not pixels), then this value is ignored and the linetype value is used
- [BoundaryPrintColor](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/boundaryprintcolor.md): Print color to apply for the boundary curves. Default is Color.Empty which means get the color from the source where this section style came from (object attributes or layer)
- [BoundaryVisible](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/boundaryvisible.md): Should the boundary for this section be displayed
- [BoundaryWidthScale](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/boundarywidthscale.md): Scale applied to the boundary wire thickness
- [ComponentType](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/componenttype.md): Returns [ModelComponentType.SectionStyle](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.modelcomponenttype.md).
- [HatchIndex](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/hatchindex.md): Hatch pattern to use when drawing a fill pattern
- [HatchPatternColor](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/hatchpatterncolor.md): Color to apply for the hatch pattern. Default is Color.Empty which means get the color from the source where this section style came from (object attributes or layer)
- [HatchPatternPlotWeightMillimeters](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/hatchpatternplotweightmillimeters.md): Plot width of the hatch pattern curves. values less than -1 (-10 is default): plot weight is determined by the object's attributes -1: do not plot 0: use default weight defined by the print dialog positive values are thicknesses in millimeters to print to
- [HatchPatternPrintColor](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/hatchpatternprintcolor.md): Print color to apply for the hatch pattern. Default is Color.Empty which means get the color from the source where this section style came from (object attributes or layer)
- [HatchRotationRadians](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/hatchrotationradians.md): Rotation to apply to the hatch patterh
- [HatchScale](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/hatchscale.md): Scale to apply to the hatch pattern
- [InUse](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/inuse.md): Returns true if a section style is use by an object, layer, or instance definition.
- [IsUnset](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/isunset.md): Returns true if the section style is unset.
- [SectionFillRule](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/sectionfillrule.md): Rule to determine when to generate a hatch pattern and fill

## Methods

- [GetBoundaryLinetype](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/getboundarylinetype.md): Get an optional custom linetype associated with this section style. If null, then the linetype will come from the parent attributes or layer
- [ReadFromFile](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/readfromfile.md): (static) Reads linetypes from a Rhino .3dm file.
- [RemoveBoundaryLinetype](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/removeboundarylinetype.md)
- [SetBoundaryLinetype](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.sectionstyle/setboundarylinetype.md)
