## Methods

### ~DirectionSymmetric()

```csharp
protected ~DirectionSymmetric()

```

### 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)

An  that describes the XML representation of the object that is produced by the  method and consumed by the  method.

### IsParametric(enRefType)

Gets parametric.

```csharp
public override bool IsParametric(Primitive.enRefType type)

```

#### Parameters

`type` Primitive.enRefType

Point picking type.

#### Returns

[bool](https://learn.microsoft.com/dotnet/api/system.boolean)

If set to `true` is parametric; otherwise, `false` is none parametric.

### 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.
