# ISch_Polygon interface

Polygons are multi-sided graphical elements. The vertices of a polygon object denote the link of lines to describe its outline.

```csharp
public interface ISch_Polygon : ISch_GraphicalObject
```

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

**Inherits:** [ISch_BasicContainer](https://altiumdeveloper.github.io/ad-sdk-docs/reference/sch/ISch_BasicContainer.md) → [ISch_GraphicalObject](https://altiumdeveloper.github.io/ad-sdk-docs/reference/sch/ISch_GraphicalObject.md)

**Derived:** [ISch_BasicPolyline](https://altiumdeveloper.github.io/ad-sdk-docs/reference/sch/ISch_BasicPolyline.md), [ISch_CollapsiblePolygon](https://altiumdeveloper.github.io/ad-sdk-docs/reference/sch/ISch_CollapsiblePolygon.md)

### IsSolid

*No description yet.*

```csharp
bool GetState_IsSolid();
void SetState_IsSolid(bool argValue);
```

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

### LineWidth

The `LineWidth` property defines the border width of the polygon with one of the following values from the [`TSize`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/sch/TSize.md) enumerated type.
