# Fit Circle

> **Note:** **What is it about?**
>
> This page documents the **Fit Circle command** in **Cinema 4D**. It reshapes selected points, edges or polygons into a circular arrangement — convenient for creating round openings for pipes, portholes or bolt holes in quad-based meshes.

This command works in all 3 component modes - Point, Edge, Polygon - and transforms selected elements into an (approximate) circular shape.

This can look like this, for example:

![Image: R26_fitcircle1.png](https://help.maxon.net/c4d/en-us/Content/Resources/Images/R26_fitcircle1.png)\
On the left the selected starting position, above different rounding, below different size resp. different radius.

The tool can only work if selected points and edges form at least a closed line segment - which is always the case with polygons. This tool delivers the best results if the selections are approximately square - bordering polygons will then have to be distorted less.

The [Smooth Edges](https://help.maxon.net/c4d/en-us/Content/html/TOOLEDGESMOOTH.html.md) tool can be used to create rounded, loop-shaped gradients from unclosed line segments.

The interactive tool changes the **Size** or **Radius** of the circular selection depending on the activated **Absolute Radius** option when dragging with the mouse button pressed.

If you also press the "Shift" key while working in the view, the **Angle** can be changed.
