# IPCB_Group interface

The base interface of PCB objects that contain other primitives: [`IPCB_Component`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Component.md), [`IPCB_LibComponent`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_LibComponent.md), [`IPCB_Net`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Net.md), [`IPCB_Polygon`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Polygon.md), [`IPCB_SplitPlane`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_SplitPlane.md), [`IPCB_Coordinate`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Coordinate.md), [`IPCB_Dimension`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Dimension.md) and their descendant interfaces.

```csharp
public interface IPCB_Group : IPCB_Primitive
```

**Namespace:** PCB · **Assembly:** Altium.SDK.Interfaces

**Inherits:** [IPCB_Primitive](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Primitive.md)

**Derived:** [IPCB_Component](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Component.md), [IPCB_Coordinate](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Coordinate.md), [IPCB_Dimension](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Dimension.md), [IPCB_LibComponent](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_LibComponent.md), [IPCB_Net](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Net.md), [IPCB_Polygon](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Polygon.md), [IPCB_SplitPlane](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_SplitPlane.md)

## Remarks

A group is composed of child primitives such as arcs, tracks and fills: for example, a polygon consists of tracks and arcs, and a footprint in a PCB library of arcs, pads and tracks.

[`GroupIterator_Create`](#groupiterator_create) and [`GroupIterator_Destroy`](#groupiterator_destroy) iterate over the child primitives; [`AddPCBObject`](#addpcbobject) and [`RemovePCBObject`](#removepcbobject) add and remove them. [`XLocation`](#xlocation) and [`YLocation`](#ylocation) are the reference point of the group.

## Properties

| Property | Type | Access | Description |
| --- | --- | --- | --- |
| [LayerUsed](#layerused) | `bool` | get; set | Whether a child primitive of the group is on the given layer. |
| [PrimitiveLock](#primitivelock) | `bool` | get; set | Whether the child primitives of the group can be edited individually or only as part of the group. |
| [XLocation](#xlocation) | `int` | get; set | The X coordinate of the reference point of the group, in internal units (10,000 per mil). |
| [YLocation](#ylocation) | `int` | get; set | The Y coordinate of the reference point of the group, in internal units (10,000 per mil). |

### LayerUsed

Whether a child primitive of the group is on the given layer.

```csharp
bool GetState_LayerUsed(TV6_Layer argL);
void SetState_LayerUsed(TV6_Layer argL, bool argValue);
```

**Type:** `bool` · **Access:** read/write · **Index:** `argL` ([TV6_Layer](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/TV6_Layer.md))

The accessors are extension methods of `IPCB_GroupHelper` (`using PCB;`).

The value is valid after [`SetState_LayersUsedArray`](#setstate_layersusedarray) has run. Until the layer usage of the group has been built (by [`SetState_LayersUsedArray`](#setstate_layersusedarray) or by assigning a value), reading returns false.

### PrimitiveLock

Whether the child primitives of the group can be edited individually or only as part of the group.

```csharp
bool GetState_PrimitiveLock();
void SetState_PrimitiveLock(bool argValue);
```

**Type:** `bool` · **Access:** read/write

### XLocation

The X coordinate of the reference point of the group, in internal units (10,000 per mil).

```csharp
int GetState_XLocation();
void SetState_XLocation(int argX);
```

**Type:** `int` · **Access:** read/write

Assigning a different value moves the group with [`MoveToXY`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Primitive.md#movetoxy), keeping its Y coordinate.

**Examples:** [Extension_PCBUndoRedo](https://github.com/AltiumDeveloper/ad-sdk-examples/blob/5b144f54740a53ec578b3b6c3f902b831e0b1144/Extension_PCBUndoRedo/Source%20Code/Commands.cs#L49), [Extension_PcbLibComponentToSTEP](https://github.com/AltiumDeveloper/ad-sdk-examples/blob/5b144f54740a53ec578b3b6c3f902b831e0b1144/Extension_PcbLibComponentToSTEP/Source%20Code/Commands.cs#L47), [Extension_PlaceAndMovePcbComponent](https://github.com/AltiumDeveloper/ad-sdk-examples/blob/5b144f54740a53ec578b3b6c3f902b831e0b1144/Extension_PlaceAndMovePcbComponent/Source%20Code/Commands.cs#L39)

### YLocation

The Y coordinate of the reference point of the group, in internal units (10,000 per mil).

```csharp
int GetState_YLocation();
void SetState_YLocation(int argY);
```

**Type:** `int` · **Access:** read/write

Assigning a different value moves the group with [`MoveToXY`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Primitive.md#movetoxy), keeping its X coordinate.

**Examples:** [Extension_PcbLibComponentToSTEP](https://github.com/AltiumDeveloper/ad-sdk-examples/blob/5b144f54740a53ec578b3b6c3f902b831e0b1144/Extension_PcbLibComponentToSTEP/Source%20Code/Commands.cs#L48), [Extension_PlaceAndMovePcbComponent](https://github.com/AltiumDeveloper/ad-sdk-examples/blob/5b144f54740a53ec578b3b6c3f902b831e0b1144/Extension_PlaceAndMovePcbComponent/Source%20Code/Commands.cs#L40)
