# Quick Start

1. Create a **Sphere** (poly).
2. Select a face and **Extrude** it.
3. Create a **ProSet** via one of the 3 options below:
   1\.
   1. *Create > Mainframe Labs > Create ProSet* 
   2. Drag your Sphere into the [Modelling Tools](https://scenegroup.gitbook.io/prosets/user-interface#modelling-tools) window 
   3. Select **polyExtrudeFace** from the pop up window and hit **Continue**.
   4. 1. Select your mesh
      2. With **alt/opt** held down click the ProSet shelf icon.
      3. Select your modelling tool from the pop up window and click **Continue**.
   5. 1. *Create > Mainframe Labs > Create ProSet*
      2. Drag the modelling tool (eg. polyExtrude) from the **Node Editor** into the [Modelling Tools](https://scenegroup.gitbook.io/prosets/user-interface#modelling-tools)

          on the ProSet.
4. Check **Use Modulus**.

Every second face should now be extruded.

{% hint style="warning" %}
Adding multiple modelling tools from the same mesh to the same ProSet can cause graph cycles, these are usually safe, but generate a lot of warnings, so you might want to avoid them.
{% endhint %}
