title: Ngon
order: 3
---

A polygon of any shape, extruded the same distance on both sides of the object's local XY plane. Every corner has its own rounding and profile, concave corners included.

## Settings

| Setting | Default | Range | What it does |
|---|---|---|---|
| **Points** | a square | 3 corners or more | One row per corner: its index, **X** and **Y** on the Ngon's plane, its **Rounding** (≥ 0, soft 2), its **Smooth** (≥ 0, soft 0.5; greyed unless the corner is a chamfer) and its profile (icon menu: *Round*, *Sharp*, *Soft*, *Tight*, *Chamfer*). Click a row to make that corner active |
| `+` / `−` | | | Add a corner after the active one; remove the active one |
| **Depth** | `1` | > 0 (soft 10) | How far the polygon extends on each side of its plane: the Ngon is twice this thick |
| **Profile** | *Round* | *Round* · *Sharp* · *Soft* · *Tight* · *Chamfer* | The shape of the top and bottom rims' rounding |
| **Rounding** | `0` | ≥ 0 (soft 2) | Rounds the top and bottom rims |
| **Smooth** *(Chamfer)* | `0` | ≥ 0 (soft 0.5) | Rounds the seams where the rims' chamfer meets the faces |

The rows every shape has are in [Properties Panels](../../interface/panels.md#rows-every-shape-has). On a scaled Ngon, **Rebuild Mesh** bakes the scale into the corners; their rounding scales by the smaller of the X and Y scale.

## Corners

The corners show only in the Chisel tool's [Edit mode](../../interface/edit-mode.md) (`Tab`). Click, `Shift`-click or a box drag on empty space selects them; a selected corner is blue. `G` moves the selection (`X`, `Y` or `Z` locks a world axis), and `X` or `Delete` removes it, down to three corners.

| Handle | Looks like | What it does | Keys while dragging |
|---|---|---|---|
| Corner | a dot on each corner | Drag: moves every selected corner on the Ngon's plane | `Ctrl` snaps to `0.1` (`Ctrl + Shift`: `0.01`), `Alt` slides along an edge, `Shift` is precision |
| Rounding handle | an orange dot just outside a selected corner | Drag away from the corner: rounds every selected corner | `1`–`5`: Round, Sharp, Soft, Tight, Chamfer; `S`: the chamfer's Smooth |
| Add dot | a green dot at the middle of the edge under the mouse | Click: adds a corner there | |

The right-click menu in Edit mode sets the selected corners' profile (*Corner Profiles*) and removes them, see [Edit Mode](../../interface/edit-mode.md#the-right-click-menu-in-edit).

## Bevel arc

In Object mode, the green Bevel arc of the [adjust arcs](../../interface/gizmos.md#adjust-arcs) rounds every corner of every selected Ngon by the same amount. A corner's rounding never takes more than half of either edge next to it. During the drag `1`–`5` set every corner's profile and `S` drags the chamfers' Smooth.

## Redo panel

After adding, the redo panel (`F9`) has:

| Setting | Default | Range | What it does |
|---|---|---|---|
| **Size** | `2` | > 0 | Side of the starting square, and twice the Depth |
| **Align** | *World* | *World* · *View* · *3D Cursor* | Rotation of the new shape |

## Limits and known issues

> [!warning]
> Moving the object's origin (*Set Origin*, or a move with *Affect Only Origins*) leaves the outline in place: the origin moves within the Ngon's plane but not along its depth.

> [!warning]
> Seen from above, the top edges of an Ngon's far sides can look wavy in the viewport. Raising **Max Steps** does not change it. A [Prism](prism.md) with the same regular outline draws them straight.

A [Smooth](../../modifiers/smooth.md) modifier leaves the corner rounding alone.
