# Beam to Slab

<figure><img src="/files/YqdDALujAIwpwi1E3xmT" alt="" width="280"><figcaption></figcaption></figure>

**Beam to Slab** simplifies structural projects by automatically detecting and attaching beams to the nearest upper floor. It enhances alignment between beams and floors, boosting workflow efficiency and reducing the need for manual adjustments. This add-in accurately identifies floors directly above beams, facilitating precise and seamless attachment with minimal user input.

## Features

* **Upper Floor Recognition:**\
  Automatically identifies and attaches beams to the closest floor above in the Z-axis direction. The 'Offset Limit' allows users to set a specific detection range.
* **Reference Plane Setting:**\
  Choose to attach beams to either the top or bottom surface of the floor.
* **Orientation Options:**
  * Normal: Aligns beams perpendicular to sloped floors modified with Slope Arrow. Does not support curved floors.
  * Horizontal: Keeps beams horizontal regardless of the floor's slope.

## Notes

* Movement of curved beams is not supported.
* Detects the nearest floor based on the beam's central point.
* Recognizes only floors that overlap with or are above the beam.
* For curved floors, only the 'Horizontal' orientation is supported.
* Beams attach to floors based on the central point of the beam's top surface.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://bimil.gitbook.io/docs/add-ins/beam-to-slab.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.
