 # Class OrientationLinkDelta

 Last update: 16.07.2025 

Namespace: [VM.Managed](VM.Managed.md)  
Assembly: VMAppCore.dll

This class is to represent the information of orientation through Design Frame. Delta orientation is getting transformation's orientation.

## 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)

### 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.
