# Set Edge Flow

> **Note:** **What is it about?**
>
> This page describes the **Set Edge Flow tool** in **Cinema 4D**. It adapts selected edge loops to the curvature implied by their neighbors — a topology polish tool that makes inserted loops follow the surface instead of flattening it.

This interactive tool - drag in the view while holding down the mouse button to regulate the **Tension** - works only in Edge mode. Selected Edges/Edge Loops will adapt to the surface curvature created by parallel Edges/Edge Loops.

On the left, the initial position; on the right, the result with the **Equal Spacing** option enabled.

If the edges perpendicular to an edge selection form a closed loop (e.g., all perpendicular edges in the case of a cube with multiple subdivisions), the tool cannot function out of principle. It can help to select only every other edge segment.
