# Initialize Primitives

A collection of primitive initializers and sliders to customize edge loop resolution of the generated mesh.

> **Note:** Tap an primitive's button to **Initialize** its shape as a new subtool with applied x/y/z resolution settings.

Palettes > Tool > Initialize

> **Note:** Clicking any of these primitive **Initialize** generators replaces the selected subtool. Undo action is supported to restore the previous model.

> **Tip:** To avoid replacing a subtool, add a temporary mesh with **Insert** > **Append** to be replaced by the chosen primitive. Also, **Duplicate** an existing subtool to be replaced by the generated primitive.

> **Note:** ZBrush for iPad's **Initialize** options work just the same as in ZBrush desktop. Learn more in our external ZBrush **[Initialize](https://help.maxon.net/zbr/en-us/#html/reference-guide/tool/polymesh/initialize/initialize.html)** documentation.

## Initialize Primitive vs Primitive3D

> **Note:** Initializing primitives (1) is different than Primitive3D (2) objects offered in the Tool palette.
>
> The **Initialize** menu for primitives is accessible in the Tool palette only when a PolyMesh3D object is selected.

> **Note:** Learn more in the [Primitive3D](https://help.maxon.net/zbp/en-us/Content/html/4_palettes_tool-3-primitives3D.html.md) section provided in this guide.
