## Methods

### CreatePatchset(MeshDocument, IEnumerable<Patch>, string, ExpressionValueVariable?, ExpressionValueVariable?, SurfaceSmoothing, Color?)

Create .

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