# Chimney - Collar Beam Replacement

At the top edge of the dialog box there is again the option to save the dialog box settings under any desired name. Under this name the setting can then be selected and used in the chimney input.

**Ident number**: Enter the identification number of the replacement collars here or check the checkbox at the right end of the field. If you enable this checkbox, the field for the identification number is deactivated, because the identification number of the replaced collars is then automatically adopted.

**Width**: Enter the width of the replacement pieces, or check the checkbox here as well so that the width is adopted from the replaced collars.

**Height**: Enter the height of the replacement pieces, or check the checkbox here as well so that the height is adopted from the replaced collars.

**Replacement direction**: For chimneys that are installed at an angle to the rafters, you can determine here whether the collars should nevertheless be generated parallel to the chimney (= angled to the rafters/collars) or whether they should continue to be generated perpendicular to the rafters/collars.

**Connection**: Connection between the replacement pieces and the collars. A selection can be made between the saved settings of different connection treatments.

## 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/offnungen/kamin/kamin-kehlbalkenauswechslung.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.
