# IRoom interface

The `IRoom` interface is a PCB room object. A room is controlled by the room design rule. This room serves as a boundary constraint for a group of specified components as a component or channel class.

```csharp
public interface IRoom : IDMObject
```

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

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

## Methods

| Method | Returns | Description |
| --- | --- | --- |
| [DM_HX](#dm_hx) | `int` | Returns the higher X coordinate of the room object. |
| [DM_HY](#dm_hy) | `int` | Returns the higher Y coordinate of the room object. |
| [DM_Layer](#dm_layer) | `int` | Returns the PCB Layer value of the room object that it is on. |
| [DM_LX](#dm_lx) | `int` | Returns the lower X coordinate of the room object. |
| [DM_LY](#dm_ly) | `int` | Returns the lower Y coordinate of the room object. |
| [DM_RoomName](#dm_roomname) | `string` | The method returns the room name. |
| [DM_Scope1Expression](#dm_scope1expression) | `string` | The method returns the scope 1 expression which describes the scope of this room object. |
| [DM_SetRoomPCBHandle](#dm_setroompcbhandle) | `void` |  |
