# IPCB_SplitPlane interface

A split plane on an internal plane layer, an area of the plane bounded by an outline and poured as regions.

```csharp
public interface IPCB_SplitPlane : IPCB_Group
```

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

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

## Remarks

Split planes can be placed only on internal plane layers. They are group objects: the regions created when a split plane is poured (`Pour`) are its child objects. Use [`GroupIterator_Create`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Group.md#groupiterator_create) and [`GroupIterator_Destroy`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Group.md#groupiterator_destroy) to iterate them.

Polygon pours are represented by [`IPCB_Polygon`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/IPCB_Polygon.md), not by this interface.

## Properties

| Property | Type | Access | Description |
| --- | --- | --- | --- |
| [AreaSize](#areasize) | `double` | get; set | The area enclosed by the split plane's outline, in square internal units. |
| [HitPrimitive](#hitprimitive) | `bool` | get | Whether the given primitive touches the split plane's outline or lies inside it. |
| [PointCount](#pointcount) | `int` | get; set | The number of segments in the split plane's outline. |
| [Segments](#segments) | [PolySegment](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/PolySegment.md) | get; set | The segments of the split plane's outline, by index. |
| [StrictHitTest](#stricthittest) | `bool` | get | Whether the given point lies inside the split plane's bounding rectangle and inside its outline. |

### AreaSize

The area enclosed by the split plane's outline, in square internal units.

```csharp
double GetState_AreaSize();
void SetState_AreaSize(double argValue);
```

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

The value is approximate: it does not take the width of the outline into account. [`SetState_XSizeYSize_1`](#setstate_xsizeysize_1) recalculates it from the outline; an assigned value is stored as given.

### HitPrimitive

Whether the given primitive touches the split plane's outline or lies inside it.

```csharp
bool GetState_HitPrimitive(IPCB_Primitive argPrimitive);
```

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

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

Returns true when the primitive's reference point is inside the outline or the primitive overlaps one of the outline's segments. Returns false for null.

### PointCount

The number of segments in the split plane's outline.

```csharp
int GetState_PointCount();
void SetState_PointCount(int argValue);
```

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

### Segments

The segments of the split plane's outline, by index.

```csharp
PolySegment GetState_Segments(int argI);
void SetState_Segments(int argI, PolySegment argValue);
```

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

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

Each segment is a line (`Kind` is `TPolySegmentType.ePolySegmentLine`) given by its vertex `Vx`, `Vy`, or an arc (`TPolySegmentType.ePolySegmentArc`) given by its center `Cx`, `Cy`, its `Radius` and the angles `Angle1` and `Angle2`. Coordinates are in internal units (10,000 per mil). Valid indexes are from 0 to [`PointCount`](#pointcount) inclusive; any other index returns a segment with all fields zero, and assigning a segment at such an index does nothing. After changing the outline, call [`SetState_XSizeYSize_1`](#setstate_xsizeysize_1) to recalculate the bounding rectangle and [`AreaSize`](#areasize).

**See also:** [PolySegment](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/PolySegment.md)

### StrictHitTest

Whether the given point lies inside the split plane's bounding rectangle and inside its outline.

```csharp
bool GetState_StrictHitTest(int argHitX, int argHitY);
```

**Type:** `bool` · **Access:** read-only · **Index:** `argHitX` (`int`): The X coordinate of the point, in internal units (10,000 per mil)., `argHitY` (`int`): The Y coordinate of the point, in internal units (10,000 per mil).
