# Field class

```cs
[DebuggerDisplay("{ValueAsObject()}", Name = "{Name}")]
public abstract class Field
```

Generic data fields used to add publicly accessible properties to RenderContent.FieldDictionary. These should be created by calling a FieldDictaionary.Add() method on a Render content object. These are allocated after the RenderContent object's C++ object is created and added to the underlying C++ objects content dictionary, who ever allocates a field is responsible for deleting it so these objects clean up the C++ pointers when they are disposed of.

## Constructors

- [Field](https://developer.rhino3d.com/api/rhinocommon/type/rhino.render.fields.field/ctor.md): (5 overloads)

## Properties

- [AutomaticRegisteredProperty](https://developer.rhino3d.com/api/rhinocommon/type/rhino.render.fields.field/automaticregisteredproperty.md)
- [IsHiddenInAutoUI](https://developer.rhino3d.com/api/rhinocommon/type/rhino.render.fields.field/ishiddeninautoui.md): When fields are used by the automatic UI, they can be hidden from it by calling this method.
- [Key](https://developer.rhino3d.com/api/rhinocommon/type/rhino.render.fields.field/key.md): (obsolete) Field name value string passed to the constructor
- [Name](https://developer.rhino3d.com/api/rhinocommon/type/rhino.render.fields.field/name.md): Field name value string passed to the constructor.
- [Tag](https://developer.rhino3d.com/api/rhinocommon/type/rhino.render.fields.field/tag.md): Gets or sets an object that contains data to associate with the field.
- [TextureAmountMax](https://developer.rhino3d.com/api/rhinocommon/type/rhino.render.fields.field/textureamountmax.md): Set Max value for Texture amount
- [TextureAmountMin](https://developer.rhino3d.com/api/rhinocommon/type/rhino.render.fields.field/textureamountmin.md): Set Min value for Texture amount
- [UseTextureAmount](https://developer.rhino3d.com/api/rhinocommon/type/rhino.render.fields.field/usetextureamount.md): True if 'texture amount' is in use, otherwise false. The 'texture amount' is represented as a numeric stepper in the UI. If true, then the stepper is shown. If false, then the stepper is hidden.
- [UseTextureOn](https://developer.rhino3d.com/api/rhinocommon/type/rhino.render.fields.field/usetextureon.md): True if 'texture on' is in use, otherwise false. In the UI 'texture on' is represented as a checkbox. If true then the checbox is shown. If false then the checkbox is not shown.
