```cs
public sealed class WorksessionFileModel : IDisposable
```

A model in a Rhino worksession (.rws) file.

## Constructors

- [WorksessionFileModel](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.worksessionfilemodel/ctor.md): (3 overloads) Creates a reference model with no paths and no layer overrides.

## Finalizer

- [~WorksessionFileModel](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.worksessionfilemodel/finalize.md): Releases the native model.

## Properties

- [FullPath](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.worksessionfilemodel/fullpath.md): Gets or sets the full path of the model file, as saved. Nothing checks that it exists.
- [IsActive](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.worksessionfilemodel/isactive.md): Gets or sets whether this is the model that was active when the worksession was saved. Every other model is a reference model.
- [LayerOverrideCount](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.worksessionfilemodel/layeroverridecount.md): Gets the number of layer overrides. Rhino does not save or use layer overrides for the active model. Version 4 files do not have them.
- [RelativePath](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.worksessionfilemodel/relativepath.md): Gets or sets the path of the model file relative to the .rws file, as saved. Rhino uses it when the file is no longer at [WorksessionFileModel.FullPath](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.worksessionfilemodel/fullpath.md). It can be empty. Version 4 files do not have it.
