# Inbuilt data

## Overview

Models comes with some data that is always available to you when using the software. This includes:

* Some Model templates
* Number Formats
* Useful Tags

You won't be able to edit or delete inbuilt items, though some inbuilt items (like Models) can be copied.

Inbuilt data can be easily identified by looking for the padlock icon, as shown in the example below:

## Inbuilt Namespaces

You cannot add items to the inbuilt Namespaces. If copying an inbuilt item, you will be asked to choose a Namespace of your own to copy the item to.
