OrientationOneDirection(DirectionBase) Initializes a new instance of the class. ```csharp public OrientationOneDirection(DirectionBase dirZ) ``` #### Parameters `dirZ` [DirectionBase](VM.Managed.DirectionBase.md) The z-direction. ### OrientationOneDirection() Initializes a new instance of the class. ```csharp public OrientationOneDirection() ``` ## Properties ### IsParameterized Gets the parametric. ```csharp public override bool IsParameterized { get; } ``` #### Property Value [bool](https://learn.microsoft.com/dotnet/api/system.boolean) ### Value Gets the information of orientation(OMatrix type). ```csharp public override OMatrix Value { get; set; } ``` #### Property Value [OMatrix](VM.Managed.OMatrix.md) ### ZDirection Gets or sets z-direction. ```csharp public DirectionBase ZDirection { get; set; } ``` #### Property Value [DirectionBase](VM.Managed.DirectionBase.md) ## Methods ### GetSchema() This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return nullNothingnullptra null reference (Nothing in Visual Basic) (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the XmlSchemaProviderAttribute to the class. ```csharp public override XmlSchema GetSchema() ``` #### Returns [XmlSchema](https://learn.microsoft.com/dotnet/api/system.xml.schema.xmlschema) ### LinkRequestUpdate(object, LinkEventArgs) The update event occured from the linked object. ```csharp protected override void LinkRequestUpdate(object objNotifier, LinkEventArgs arg) ``` #### Parameters `objNotifier` [object](https://learn.microsoft.com/dotnet/api/system.object) The linked object. `arg` [LinkEventArgs](VM.Managed.LinkEventArgs.md) The update event information. ### ReadXml(XmlReader) Generates an object from its XML representation. ```csharp public override void ReadXml(XmlReader reader) ``` #### Parameters `reader` [XmlReader](https://learn.microsoft.com/dotnet/api/system.xml.xmlreader) The XmlReader stream from which the object is deserialized. ### WriteXml(XmlWriter) Converts an object into its XML representation. ```csharp public override void WriteXml(XmlWriter writer) ``` #### Parameters `writer` [XmlWriter](https://learn.microsoft.com/dotnet/api/system.xml.xmlwriter) The XmlWriter stream to which the object is serialized.
