## Methods

### CreateEHDBearing(GearTrainDocument, Obj, Obj, Vector, Vector, Vector, ExpressionValueVariable, ExpressionValueVariable, ExpressionValueVariable, string)

Create .

```csharp
[NotNull(new string[] { "document" })]
[NotNullObj(new string[] { "baseGeometry", "actionGeometry" })]
[NotZeroMagnitude(new string[] { "zAxis", "xAxis" })]
[GreaterThanZero(new string[] { "baseRadius", "actionRadius", "width" })]
public static Obj CreateEHDBearing(this GearTrainDocument document, Obj baseGeometry, Obj actionGeometry, Vector position, Vector zAxis, Vector xAxis, ExpressionValueVariable baseRadius, ExpressionValueVariable actionRadius, ExpressionValueVariable width, string ehdBearingName = "")
