Rotate given  by using rotation axis and angle(degree).

```csharp
[NotNull(new string[] { "objs" })]
[NotZeroMagnitude(new string[] { "direction" })]
public static void RotateObjectsDegree(IEnumerable<Obj> objs, Vector position, Vector direction, double rotateAngleDegree)

```

#### Parameters

`objs` IEnumerable&lt;[Obj](VM.API.Pre.Obj.md)&gt;

The collection of  to rotate.

`position` Vector

The position of the axis.

`direction` Vector
