# Sheathing and Paneling - Recalculate

Recalculate formwork: The formwork and sheathing of all layers of the selected roof surfaces are recalculated. If components of formwork and sheathing already exist in the affected layers, they will be deleted first.

One or multiple roof surfaces can be recalculated. The following function calls are available for this purpose:

**All roof surfaces**: All roof surfaces of the current building are selected.

**Building contour**: All roof surfaces of the subsequently selected building contours are assigned.

**Roof surfaces**: Afterwards, the desired roof surfaces can be selected individually. Multiple surfaces can also be assigned simultaneously.

The definitions of formwork and paneling that are located in a roof surface can be checked via the roof-surface execution. For this, the first column in the roof-surface execution is switched from 'Texture > B' to 'Occupation > T'. The occupations are then displayed in that column; the browse button next to it allows you to display, verify, and, if necessary, adjust the occupation.

## 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.dietrichs.com/dietrichs-intelligent-documentation/docs-de-en/design-program/modellbereiche/dach/dachbereiche/schalung-und-beplankung/schalung-und-beplankung-neuberechnen.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.
