# Adding or Modifying Loads in ENERCALC SEL

How live and roof live loads added or modified in ENERCALC SEL during reduction are stored unreduced in Revit.

It is advisable for users to remain aware of whether live load reduction is currently active in an ENERCALC SEL calculation at any given time. Although there is not a direct indication of reduction status within the ENERCALC SEL interface, the reduction settings are managed during calculation launch from Revit as previously described.

{% hint style="warning" %}
**NOTE**: Any live loads (LL) or roof live loads (LR) that are added or modified from the ENERCALC SEL interface while LL or LR reduction is active in a calculation will be treated as REDUCED magnitudes. This load will then be created or updated in the Revit model with an “unreduced” magnitude obtained by ***dividing*** the reduced magnitude by the applicable reduction factor.
{% endhint %}

This process prevents loads from being stored in the Revit model with a magnitude that reflects code provisions unique to only one specific element and allows loading in the Revit model to remain valid even when the LL reduction settings on various elements change over time.

If this behavior is undesirable, loads may be modified directly from the Revit model, or from ENERCALC SEL calculations where LL reduction is not activated.

In the example below, a calculation for a floor beam supporting long-span deck is launched with LL reduction activated.

Since LL reduction was activated during launch, all LL magnitudes displayed in the ENERCALC SEL interface are reduced.

If this live load magnitude is manually modified by the user, the newly revised magnitude is treated as a reduced magnitude.

This will result in the underlying area load in the Revit model being updated to a magnitude of:

LL = (0.08 Ksf) / 0.817 = 0.09792 Ksf

## 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/adding-or-modifying-loads-in-e.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.
