#### Parameters

`mesh` [Mesh](VM.Managed.DAFUL.FE.Mesh.md)

The mesh.

`nNodeIndex` [int](https://learn.microsoft.com/dotnet/api/system.int32)

The node index.

### PointOnNode()

Initializes a new instance of the  class.

```csharp
public PointOnNode()

```

## Properties

### IsParameterized

Get the parametric.

```csharp
public override bool IsParameterized { get; }

```

#### Property Value

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

### NodeIndex

Gets the index of node.

```csharp
public int NodeIndex { get; }

```

#### Property Value

[int](https://learn.microsoft.com/dotnet/api/system.int32)

### Value

Gets the point position.

## Methods

### GetSchema()

This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return null (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the  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.

### OnDeserialization(object)

Called when \[deserialization\].

```csharp
protected override void OnDeserialization(object sender)

```

#### Parameters

`sender` [object](https://learn.microsoft.com/dotnet/api/system.object)

The sender.

### 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  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  stream to which the object is serialized.
