Namespace: [Rhino.DocObjects](https://developer.rhino3d.com/api/rhinocommon/namespace/rhino.docobjects.md) · Assembly: [RhinoCommon](https://developer.rhino3d.com/api/rhinocommon/assembly/rhinocommon.md)

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

## Constructors

- [Linetype](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/ctor.md): (2 overloads)

## Properties

- [AlwaysModelDistances](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/alwaysmodeldistances.md): Linetype patterns and widths are typically interpreted as distances on the printed output when printing. In this case AlwaysModelDistances is false (default). When set to true, the linetype pattern and width will be interpreted as being in world distances. This is useful for cases like modeling a road as a single curve.
- [ComponentType](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/componenttype.md): Returns [ModelComponentType.LinePattern](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.modelcomponenttype.md).
- [HasShapes](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/hasshapes.md): Does this linetype have shapes
- [InUse](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/inuse.md): Returns true if the linetype is in use by a Rhino object, a layer, an instance definition, or a section style.
- [IsDeleted](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/isdeleted.md): Gets a value indicating whether this linetype has been deleted and is currently in the Undo buffer.
- [IsModified](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/ismodified.md): true if this linetype has been modified by LinetypeTable.ModifyLinetype() and the modifications can be undone.
- [IsPatternLocked](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/ispatternlocked.md): Returns true if the pattern is locked and cannot be modified.
- [IsReference](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/isreference.md): Gets a value indicting whether this linetype is a referenced linetype. Referenced linetypes are part of referenced documents.

- [ShapeGap](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/shapegap.md): If shapes are present in this linetype, this is the gap around the shape.
- [ShapeLocalOffset](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/shapelocaloffset.md): Local offset applied to shapes
- [ShapeSpacing](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/shapespacing.md): If shapes are present in this linetype, this is the distance between shapes
- [UserStringCount](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/userstringcount.md): Gets the amount of user strings.
- [Width](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/width.md): Base width for this linetype
- [WidthUnits](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.linetype/widthunits.md): Unit system that widths are defined in. UnitSystem.None is default and means that the width is defined in pixels.
