# IPart interface

The `IPart` interface is the interface of an existing schematic part on a Schematic sheet. A part object is "part" of a component, that is, a multi-part component consists of part objects. For example a multiple gate integrated circuit has duplicate gates, and that a component represents the multi-part gate and a part represents the gate itself.

```csharp
public interface IPart : IDMObject
```

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

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

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

## Remarks

An equivalent component object representation is the [`ISch_Component`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/sch/ISch_Component.md) class in Schematic API. The [`ISch_Component`](https://altiumdeveloper.github.io/ad-sdk-docs/reference/sch/ISch_Component.md) interface represents a component that can contain links to different model implementations such as PCB, Signal Integrity and Simulation models. Only one model of a particular model type (PCB footprint, SIM, SI, EDIF Macro and VHDL) can be enabled as the currently linked model, at any one time.
