# PropertyId enum

Namespace: [Grasshopper2.UI.Skinning](https://developer.rhino3d.com/api/gh2/namespace/grasshopper2.ui.skinning.md) · Assembly: [Grasshopper2](https://developer.rhino3d.com/api/gh2/assembly/grasshopper2.md)

```cs
[Flags]
public enum PropertyId
```

Identifies a single property of a skin. An identifier is composed of one mode bit, one family bit, one role bit and zero or more variant bits, so the selected, hidden and disabled versions of a property share a role rather than being duplicated. Not every combination exists; the set of real properties is enumerated by [SkinProperties.All](https://developer.rhino3d.com/api/gh2/type/grasshopper2.ui.skinning.skinproperties/all.md), and each role below says which families use it.
