title: Sweep
order: 10
---

Sweep runs a shape along a path of points: the shape is the cross-section, the path its spine. The two open ends are closed with the shape's own form, so its **Rounding** and **Bevel** style them.

## Settings

![the Sweep modifier in the panel, with three points](../assets/modifiersettings-sweep.webp)

| Setting | Default | Range | What it does |
|---|---|---|---|
| **Point 0**, **Point 1**, … **X** / **Y** / **Z** | `0, 0, 0` and a point on local +Z, twice the shape's largest size away (at least `1` m) | | The path's points, in order, in the shape's own space: the path moves, turns and scales with the object |
| **×** beside a point | | | Removes that point. Greyed out with two points left |
| **Rounding** (after every inner point) | `0` m | `0` and up (soft `10`) | That corner's arc radius. `0` is a sharp corner. A radius larger than the corner can hold stops at the largest arc that fits between the neighbouring points |
| **Add Point** | | | Adds a point past the last one |

## Path handles

Each Sweep's path on the active, selected shape draws with a handle on every point while the Chisel tool is active.

| Handle | Looks like | Drag or click | Keys while dragging |
|---|---|---|---|
| Point dot | Blue dot on every point | Drag to move the point, parallel to the view. Hover and press `X` or `Delete` to remove it; a path keeps two | `X` / `Y` / `Z` lock to that axis of the shape (again to unlock), hold `Ctrl` to slide along a segment, `Shift` precision |
| Rounding handle | Small orange dot off every inner corner | Drag away from the corner to raise its **Rounding** | |
| Add dot | Green dot at a segment's middle, when you hover near it | Click to add a point there | |

Both drags show their value beside the cursor; a locked axis shows as a line in its colour. `Space`, `Enter` or releasing the mouse confirms; `RMB` or `Esc` cancels and puts the point back.

Switch the handles with **Sweep** in the tool header's [gizmo drop-down](../interface/gizmos.md#tool-bar-switches), or *Render Properties ▸ Gizmos ▸ Modifiers ▸ Sweep*.

### In Edit

In the Chisel tool's [Edit](../interface/edit-mode.md) state the path's points select like the points of a shape: black until selected, blue once selected.

- Click, `Shift`-click or drag a box to select points.
- Drag a selected point to move them all, or press `G`; `X`, `Y` or `Z` then lock to a **world** axis.
- `X` or `Delete` removes the selected points; the path keeps at least two.
- Only a selected corner's rounding handle can be dragged, and it rounds every selected corner by the same amount.

## Pie menu

The pie's East wedge has a Sweep row showing how many points the path has.

## Limits and known issues

- A sweep has no taper or roll of its own. A [Lattice](lattice.md) below it shapes the swept result.
