# Set Object Layers

We use layers to group masses. They can be used to assign programming to groups of masses, or even used to denote building groups in a multi-building design. However due to Rhino's ability to create incredibly deeply nested layers, we only take into consideration the last leaf layers. 

Consider the following layer settings below is a a very common pattern in layer settings with conceptual designs in Rhino.

<div align="left"><figure><img src="/files/k3qvbc9aPjq8yzYlr3xu" alt=""><figcaption></figcaption></figure></div>

However since we cannot accommodate all layer settings patterns, we recommend you name your last level layers uniquely:

<div align="left"><figure><img src="/files/hdJwq7U5DaKtoV5QKGKL" alt=""><figcaption></figcaption></figure></div>

{% hint style="info" %}
We allow you to rename and group these levels so you can override them later in the exploration dashboard.
{% endhint %}
