# Remembering Tributary Conditions

How to remember, unlock, and re-validate stored beam tributary selections to speed up future calculation launches in ENERCALC for Revit.

Regardless of the method used to choose the beam tributaries, the launch window includes an option to “Remember Support Selections”.

Checking this box prior to the approval of tributary conditions will allow ENERCALC for Revit to store the identities of the approved tributaries during future launches of the calculation. This will permit rapid updating of the beam’s load linking conditions without the inconvenience of repetitive approvals. If tributaries have been stored, the launch window will not show a “Tributary Beams” tab for user approval.

If at any point it becomes necessary to choose new tributary conditions for a beam, the previously stored tributaries may be unlocked via the Element Manager. Conversely, if the tributaries were approved but not “Remembered” during the previous launch, the “Remember” option may be enabled from this same menu.

Note that even when tributary beams have been stored, the launch still includes error checking to validate the previously stored list. If a previously stored tributary no longer exists in the Revit model, then the launch will proceed without it. If a previously stored tributary does not physically intersect the beam, the launch process will revert to prompting for approval of tributary conditions.

## 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/tributary-beams14/remembering-tributary-conditio.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.
