# TObjectId enumeration

Note, the eTraceObject and eSpareViaObject values are for internal use only and are not used directly with PCB documents (these values are used for Signal Integrity and Situs auto routing modules).

```csharp
public enum TObjectId
```

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