Define rebar shapes to be placed at beam ends.
**Face Position** - select where rebar should be created: at one end of the beam, or both.
**Min/Max search distance** - important if your beam has cuts at supports
**Bar shape** - select from available rebar shapes.
**Rebar bar type** - select rebar type that should be used for these bars.
**End Cover** - used to define cover from the end of the beam. (Not active if Extend distance parameter is used.)
**Bar length** - length of selected bar. (Not active if Extend distance parameter is used.)
**Extend distance** - extension distance from the end of the beam. (Not active if End Cover is used.)
**Anchorage length** - anchorage distance of selected bar. (Not active if End Cover is used.)
**Layout rule** - select how rebar should be distributed in other direction
**Count** and **Spacing** - define parameters for Layout rule
**Top**, **Bottom**, **Left**, **Right** - covers to define size of element and restrictions for layout

## 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.besmart.software/3d-modeling-and-design/precast-concrete/feature-descriptions/beam-reinforcement/configuration-settings/support.md?ask=&goal=
```
`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.
