# Walls

Before framing walls, you need to create wall types with layers and model the walls correctly. Follow the guide below.

## 1. Create wall type layers

* Drywall and other finish layers should have **Finish 1**, **Finish 2** or **Substrate** function
* The main **studs** are hosted inside the **Structure layer** which has to be the **Core Layer** (layer between the two Core Boundaries)
* Each layer must have a defined **Function**, **Material** and **Thickness**

{% hint style="info" %}
**Suggestion**: Structure \[1] layer thickness should match the Web depth (d) of you studs. For example, if your studs are 89mm, the Structure \[1] layer should have the same thickness.
{% endhint %}

{% hint style="success" %}
You can create as many layers as you wish.
{% endhint %}

For **double** drywall or other finish layers, each **Material** name must be **unique.**

## 2. Model walls

### 2.1 Wall connections (joins)

### 2.3 Prefab walls (optional)

You can **split long walls** into **panels with gaps**, use [**Smart Walls**](https://docs.besmart.software/common-for-several-products/smart-walls):

### 3. Use clash detection (optional)

To avoid clashes and create openings in walls/floors/roofs for **services** (ducts, pipes) use [**Cut Opening**](https://docs.besmart.software/3d-modeling-and-design/cut-opening/mep-opening-creation)**.**

{% hint style="info" %}
You can also use **Cut Opening** after framing is modeled. [Learn more](/3d-modeling-and-design/metal-framing/faq/clash-detection/is-there-a-clash-detection-with-linked-mep-models.md).

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://docs.besmart.software/3d-modeling-and-design/metal-framing/getting-started/building-modeling/walls.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.
