# Load Cases and Combinations

How Revit structural load cases map to ENERCALC SEL cases, including ACC1 and TEMP1 exceptions and combination handling.

Load are managed and mapped from Revit to ENERCALC SEL using the basic load cases that are created using the default Revit structural template. These cases may be viewed at any time using the native Revit button for Structural Settings on the Structure ribbon tab.

Load cases are found under Structure > Structural Settings > Load Cases. These are default settings and typically do not need to be manually created or modified in any way. Changing the default settings will interfere with the mapping of loads to the ENERCALC SEL calculation. In the table shown here, all load cases are mapped directly to the corresponding case in ENERCALC SEL, with two exceptions:

* ACC1 maps to earth load (H) in ENERCALC SEL
* TEMP1 is ignored and does not map to any case in ENERCALC SEL

Load combinations are managed exclusively from the ENERCALC SEL interface. Load combination definitions found in the Revit model will not influence the design calculations in any way.

## 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/load-cases-and-combinations.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.
