# More ProBuilder tools

Learn to create more complex 3D models in Unity using a wider range of ProBuilder tools.

In this tutorial, you'll learn how to perform more diverse modeling using various tools offered by ProBuilder.

## 1. Splitting surfaces with editing tools

To do more detailed 3D modeling, you can add more faces to the shape. You can split surfaces using various tools from the **ProBuilder** window.

The editing tools for adding, deleting, or splitting components are indicated by the **red** category. These new tools will appear in the **ProBuilder** window after you switch between **vertex**, **face**, and **edge** selection.

To do more specific 3D modeling, there have to be more surfaces. You can split surfaces with various tools in the **ProBuilder** window.

 The editing tools for adding, deleting, or splitting components are indicated as **red** categories.

## 2. Use the quick selection tool to select multiple faces

If there aren't many faces, you can simply select them manually using **Ctrl**+**left-click** (macOS: **Cmd**+**left-click**). However, ProBuilder also offers quick selection tools to simplify this process when there are many components..

The tools for selection are indicated by the **blue** category. These new tools will appear in the **ProBuilder** window after you switch to **face** selection.

![Face Ring tool to select all perimeter faces horizontally](https://connect-mediagw.unity.com/h1/20230422/learn/images/22e31538-d4c5-4f3e-879d-85714ca0e692_E04a.png)

![Grow Selection tool selects by expanding adjacent faces](https://connect-mediagw.unity.com/h1/20230422/learn/images/ce99c509-6254-4ad6-b70e-edc4654dc45b_E05a.png)

## 3. Smoothing edges

First, choose one of the edges of the shape (or from multiple shapes while holding **Shift**), then check the **Selection Edge Ring** tool, which searches horizontally around the perimeter of the shape to choose all the edges around it, then add a new face between each edge  using the **Bevel** tool.

 There is an additional settings icon in the **Bevel** tool. Hold **Alt**+**left-click** (macOS: hold **Option**+**left-click**) to open the **Settings** window. Here you can set the size of the bevel (this will depend on the shape you are working on.)

## 4. Deleting faces

 There are two main ways to delete faces:

- **Using shortcut keys**: press the **Backspace** key (macOS: **Delete** key) after selecting the desired faces.
- **Using ProBuilder tools**: select the **Delete Faces** tool after selecting the desired surfaces.

## 5. Merge surfaces

You can also merge surfaces if they are unnecessarily split. This can be also helpful to set up UV mapping more easily in some cases.

**Note**:  Merging faces does not delete the vertices in between.

## 6. Using object tools

Sometimes, after editing the shape, the center pivot might have moved. To rotate the object around its center correctly, you will need to reset the pivot to the center.

Select the **Center Pivot** tool to reset the pivot to the center of the object, regardless of the previous pivot point.

 Let’s make a new shape by overlaying the object with its upside down version. To do this, follow these instructions:

**1.**  Select the object and copy it using **Ctrl**+**D** (macOS: **Cmd**+**D**).

**2.**  Rearrange the copied object on top of the original one using the **Transform** component and gizmos.

**3.**  Multi-select the two objects with **Ctrl**+**left-click** (macOS: **Cmd**+**left-click**).

**4.**  Merge the two objects into one using the **Merge Objects** tool.

**5.**  Reset the location, rotation, and size of the new shape with the **Freeze Transform** tool.

The object tools that handle object-related features are indicated by the **green** category.

## 7. Merging vertices

The merged object might seem OK on the outside, but having two vertices sticking together in the same position might result in an unstable model.

 This can be solved using the **Weld Vertices** tool.

![](https://connect-mediagw.unity.com/h1/20230422/learn/images/08754df9-36e3-4fc1-b51f-34870ccac0e0_E15a.png)

Merge the aligned vertices with the **Weld Vertices** tool, then try to move the same vertices around to see if they are merged correctly.

**Note:**  Make sure you select all the vertices, even the ones that are hidden behind some visible faces.

![Change Select Hidden: On to select points that are not visible on the back side and work](https://connect-mediagw.unity.com/h1/20230422/learn/images/ff7693dc-4cf5-4dcb-a5df-d45ca04a10c9_E15.gif)

## 8. Challenge: Create a unique structure using various tools

![](https://connect-mediagw.unity.com/h1/20240628/learn/images/5096aea8-c255-468f-b458-0d6d3b378340_image79.gif)

Try to create a more complex 3D model based on the basic editing and tool skills you have learned so far.

You can check out the descriptions of all the other **ProBuilder tools** in the [official manual](https://docs.unity3d.com/Packages/com.unity.probuilder@5.0/manual/ref_actions.html).
