# Navigation Overview for Live Load Reduction Controls

How to navigate the live load and roof live load reduction tabs on the beam calculation launch approval window.

If ENERCALC for Revit detects one or more conditions from the above list that make the beam eligible for live load reduction, an additional tab for these controls will appear on the launch approval window.

In some unique framing conditions, a particular beam or girder may be subject to both live (LL) and roof live (LR) loads. In such cases, both sets of options will be presented to the user during the calculation launch.

As with the other approval tabs in the launch window, looking ahead to the “LL Reduction” or “LR Reduction” tabs before the preceding approvals are complete will display the controls in a “disabled” grayed-out mode.

These options automatically become available for user review and interaction after approvals have been furnished in the preceding tabs.

In any situation where the beam has loads eligible for reduction but the user does not wish to use these options, reduction may be skipped using the “Skip LL Reduction” or “Skip LR Reduction” buttons, as applicable. The decision to skip reduction will be automatically applied on future launches of the calculation.

The decision to skip floor (LL) reduction does ***NOT*** automatically skip LR reduction, and vice versa.

# 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-loads-16/live-load-reduction/navigation-overview.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.
