# Deleting Rule Definitions from a Project

How to delete beam design rule definitions from a project, including confirmations and in-use restrictions.

Beam design rule definitions may be removed using the "Delete" button. Using this button will remove the currently selected definition.

If the currently selected definition is newly added to the table during the current menu session and has never been saved, then the "Delete" button will remove it immediately without any additional confirmation required. However, if the definition has previously been saved, then the "Delete" button will trigger a warning requiring confirmation before removal:

If the currently selected definition has already been applied to one or more elements, the user will be warned that definitions cannot be removed while in use:

The elements in question may be assigned a different rule as described in [Applying Rules to Elements](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/applying-rules.md), or the rule may be erased from the elements, as described in [Erasing Rules From Elements](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/erasing-rules-from-elements.md). Once the definition is no longer assigned to any elements, it may be removed.

## 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/removing-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.
