# File3dmObjectTable class

Namespace: [Rhino.FileIO](https://developer.rhino3d.com/api/rhinocommon/namespace/rhino.fileio.md) · Assembly: [RhinoCommon](https://developer.rhino3d.com/api/rhinocommon/assembly/rhinocommon.md)

```cs
public class File3dmObjectTable : File3dmCommonComponentTable<File3dmObject>, IEnumerable<File3dmObject>
```

Represents a simple object table for a file that is open externally.

This class mimics Rhino.DocObjects.Tables.ObjectTable while providing external access to the file.
