# Adding Models

{% hint style="info" %}
You can only add **buildings** and **cars**, not roads or nature.
{% endhint %}

The file's name must start with *`add3dModels`* and each line must have 4 or 5 values which are based in:

{% content-ref url="/pages/aUBUwpCLQSJsnEj6xkqg" %}
[Structure Model Format](/urbek-modding/in-depth-knowledge/structure-model-format.md)
{% endcontent-ref %}

You'll just need to add in front of it the name of the building you wish to add the model, ending with the format:

{% hint style="info" %}
**BuildingCodeName,ModelName,TileSize,TileSize,Edge**
{% endhint %}

{% tabs %}
{% tab title="Example: Add a model" %}
Will add to the building `cabanha` the models `KCasa0020` and `KCasa0021` with a tile size of `1` x `1`, which one will be only for edges (`E`).

{% hint style="info" %}
Remember that 1x1 is the size of the model in tiles, which is 40x40 voxels each.
{% endhint %}

{% code title="add3dModels\_Example.txt" %}

```
cabanha,KCasa0020,1,1
cabanha,KCasa0021,1,1,E
```

{% endcode %}
{% endtab %}
{% endtabs %}

{% hint style="danger" %}
If you use a mod that adds new models and then delete the mod, there will be problems loading the game where you have already used it.
{% endhint %}
