# Adding Rule Definitions to a Project

How to add and save new beam design rule definitions to a project using the New button.

New beam design rules may be added to the table using the "New" button:

The "New" button will generate a new row in the table. The user may name and modify this new definition as described in [Modifying Rules](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/modifying-rules.md).

When a new rule is created and modified, it will not be permanently added to the project until saved using the "Save Changes" button. Closing the menu before saving will cause the new rule to be discarded.

A newly added beam design rule does not have any influence over the behavior of beam calculations until it is manually applied to specific elements by the user (refer to [Applying Rules to Elements](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/applying-rules.md)).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enercalc.com/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/adding-new-rules.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
