```csharp
public interface IPointList
```

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

## Properties

| Property | Type | Access | Description |
| --- | --- | --- | --- |
| [Count](#count) | `uint` | get; set |  |
| [Value](#value) | [SplinePoint2D](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/SplinePoint2D.md) | get; set |  |

### Count

*No description yet.*

```csharp
uint GetCount();
void SetCount(uint argvalue);
```

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

### Value

*No description yet.*

```csharp
SplinePoint2D GetValue(uint argIndex);
void SetValue(uint argIndex, SplinePoint2D argvalue);
```

**Type:** [SplinePoint2D](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/SplinePoint2D.md) · **Access:** read/write · **Index:** `argIndex` (`uint`)

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

## Methods

| Method | Returns | Description |
| --- | --- | --- |
| [Add](#add) | `void` |  |
| [SetPoint](#setpoint) | `void` |  |

### Add

*No description yet.*

```csharp
void Add(SplinePoint2D argvalue);
void Add(ISplinePoint2D argvalue);
```

| Parameter | Type | Passing |
| --- | --- | --- |
| `argvalue` | [SplinePoint2D](https://altiumdeveloper.github.io/ad-sdk-docs/reference/pcb/SplinePoint2D.md) | value |

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

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

### SetPoint

*No description yet.*

```csharp
void SetPoint(uint argIndex, double argX, double argY);
```

| Parameter | Type | Passing |
| --- | --- | --- |
| `argIndex` | `uint` | value |
| `argX` | `double` | value |
| `argY` | `double` | value |

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