# Add a new hierarchy to a dimension

Add new hierarchies to a dimension when you need to organize data in the dimension more granularly. 

Complete the following steps to add a new hierarchy to a dimension. 

1. Log into the **Pentaho User Console** (PUC).  
2. Open the Semantic Model Editor by taking one of the following actions:

   * If you are using the Modern Design of PUC, in the menu on the left side of the page, click **Semantic Model Editor**.
   * If you are using the Classic Design of PUC, click **File** > **Semantic Model Editor**. 

   The **Semantic Model Editor** opens. 
3. Open the semantic model that contains the cube with a dimension you want to edit by completing the following sub steps: 
   1. In the **Semantic Models** list, navigate to the model you want to open by searching or scrolling through the list. 
   2. Click **Open**. The model opens in the canvas. 
4. On the canvas, locate the cube, dimension node, and dimension you want to add the new hierarchy to. 

   <div data-gb-custom-block data-tag="hint" data-style="info" class="hint hint-info"><p><strong>Note:</strong> To locate an element in a large semantic model, you can click the <strong>Model Structure</strong> tab and then navigate to the element by searching or scrolling through the list. </p></div>
5. Click any of the **More Actions** icon available in the respective Dimension structure and select **Edit**. The **Dimension Editor** window opens for that dimension.&#x20;
6. If not yet selected, select the Dimension in the tree. Click **Add New Hierarchy**. A new hierarchy is added to the dimension with the name “Hierarchy” and a number representing the order in which the hierarchy was added to the dimension. For example, “Hierarchy2” is the second hierarchy added to the dimension. &#x20;
7. Click **Apply**. Edits to the dimension are applied.&#x20;
8. In the **Semantic Model Editor**, click **Save** to save changes to the model.&#x20;
