# Change Warnings from Removal of Child Elements

How removing a load-linked child element triggers a change warning on the girder that used its reactions in ENERCALC for Revit.

{% hint style="warning" %}
**NOTE:** For parent/child management, the terms “Add” and “Remove” describe the creation or removal of a conceptual relationship between the parent element and another existing element in the Revit model. These controls do not create or delete actual elements in the Revit model or calculations in the `.EC6` file.
{% endhint %}

Once a girder has been designed using the reactions exerted by “Load-Linked” child elements, it will also be subject to warnings in the future if one of the parent/child relationships is removed. Removal of a child that does not carry reactions has no effect, but removal of a “Load-Linked” child will trigger a warning state (orange) on the girder similar to that caused by adding a new child, as shown previously.

# 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-parent-child-relationsh/change-warnings/change-warnings-from-removal-o.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.
