# Performing Actions with ZModeler

- After choosing an Action and a Target, adjust any relevant Modifiers and tap and / or drag on the model to apply the Action.
- Each ZModeler action works by interacting with a point, edge, or polygon. When performing an action, dragging the stylus left / right or up / down will often modify its effect dynamically.
- During the Action, introducing the modifier keys further controls how the Action applies.

> **Note:** Learn more about which modifiers and modifier keys do what in the [Actions & Modifiers](https://help.maxon.net/zbp/en-us/Content/html/5_sculpting-and-painting_brushes_zmodeler-brush-actions-modifiers.html.md) section.

> **Tip:** Because ZModeler is a brush rather than a separate mode, you can switch between it and other sculpting tools anytime. Additionally, because it is polygon-based, it is fully compatible with all PolyMesh3D features.

## Replay Actions

The ZModeler Brush also features a replay function, allowing you to repeat the last Action with a single tap. This feature helps repeat modifications without manually reselecting.

### Quick Steps:

1. Apply an action. For example, extrude a single polygon at a desired distance.

2. Tap a different polygon to replay the previous extrusion onto the selected polygon.

## ZModeler Hover States

Hovering over an edge, point, or polygon displays the selected action for each respected component.

> **Note:** ZModeler takes full advantage of hover-enabled iPads for a more efficient and intuitive workflow. While non-hover devices are supported, we recommend using an iPad with hover capabilities or a mouse for the best experience when working with ZModeler.
>
> ZModeler can highlight faces, edges, and vertices directly in the UI. As shown below, hovering over a polygon (left) causes all of the polygon's edges to highlight in orange. When you hover over a single edge (center), that edge turns orange. And when you hover over a vertex (right), that intersection point turns blue.
