# Create Wall Types

## 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.

You can create as many layers as you wish.

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