This class implements APIs to create edge set.

```csharp
public static class EdgeSetAPI

```

#### Inheritance

object ← [EdgeSetAPI](VM.API.Pre.FE.EdgeSetAPI.md)

#### Extension Methods

Create .

```csharp
[NotNull(new string[] { "document", "nodeIndex" })]
public static Obj CreateEdgeset(this MeshDocument document, IEnumerable<uint> nodeIndex, string name = "", ExpressionValueVariable? maxPenetration = null, ExpressionValueVariable? offset = null, SurfaceSmoothing surfaceSmoothing = SurfaceSmoothing.AUTOMATIC, Color? color = null)

```

#### Parameters

`document` MeshDocument

The document to create edge set.

`nodeIndex` IEnumerable&lt;uint&gt;

The node indexes for creating edgeset.

`name` string

The name to be cteated edge set.

#### Returns

[Obj](https://github.com/AnsysVirtualMotion/DAFUL/blob/9110677a5f6a53d7604f8dfd35b4c5fceb59e8e0/DAFUL/ClassicPre/API/VM.API.Pre/Models/Obj.cs)

The new  object that is created by this API.

#### Exceptions

ArgumentNullException

Will be thrown if 'document' or 'nodeIndex' arguments are empty.
