### AddMechLayer

*No description yet.*

```csharp
void AddMechLayer(ICMP_MechanicalLayer argLayer);
void AddMechLayer(object argLayer);
```

| Parameter | Type | Passing |
| --- | --- | --- |
| `argLayer` | [ICMP_MechanicalLayer](https://altiumdeveloper.github.io/ad-sdk-docs/reference/edp/ICMP_MechanicalLayer.md) | value |

```

**Returns:** [ICMP_MechanicalLayer](https://altiumdeveloper.github.io/ad-sdk-docs/reference/edp/ICMP_MechanicalLayer.md)

Extension method of `ICMP_LayerStackHelper` (`using EDP;`).

### AddNewSubStack

*No description yet.*

```csharp
ICMP_SubStack AddNewSubStack();
```

**Returns:** [ICMP_SubStack](https://altiumdeveloper.github.io/ad-sdk-docs/reference/edp/ICMP_SubStack.md)

Extension method of `ICMP_LayerStackHelper` (`using EDP;`).

### AddSubStack

*No description yet.*

void AddSubStack(ICMP_SubStack argSubstack);
void AddSubStack(object argSubstack);
```

| Parameter | Type | Passing |
| --- | --- | --- |
| `argSubstack` | [ICMP_SubStack](https://altiumdeveloper.github.io/ad-sdk-docs/reference/edp/ICMP_SubStack.md) | value |

**Returns:** nothing (`void`)

The first overload is an extension method of `ICMP_LayerStackHelper` (`using EDP;`) with typed parameters; the second is declared by the interface.
