# Iron

> **Note:** **What is it about?**
>
> This page documents the **Iron tool** in **Cinema 4D**, a mesh-smoothing function. It relaxes areas where neighboring edges exceed a threshold angle, with interactive strength control — a quick fix for uneven, noisy or crumpled geometry.

If your mesh looks too uneven, smooth it out using this virtual iron. The tool works in all three modes (point, edge and polygon).

The Iron tool works by smoothing out the selection in areas where the angle between neighboring edges is equal to or greater than a threshold angle (**Angle**). The strength of smoothing is controlled by the **Percent** value.

To use the Iron tool:

Drag in the Viewport to vary the Percent value (i.e. the strength of smoothing).

`Shift`+drag in the Viewport to vary the Angle value (i.e. the threshold angle).
