Chisel

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.

Path handles

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

HandleLooks likeDrag or clickKeys while dragging
Point dotBlue dot on every pointDrag to move the point, parallel to the view. Hover and press X or Delete to remove it; a path keeps twoX / Y / Z lock to that axis of the shape (again to unlock), hold Ctrl to slide along a segment, Shift precision
Rounding handleSmall orange dot off every inner cornerDrag away from the corner to raise its Rounding
Add dotGreen dot at a segment’s middle, when you hover near itClick 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, or Render Properties ▸ Gizmos ▸ Modifiers ▸ Sweep.

In Edit

In the Chisel tool’s Edit 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.

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 below it shapes the swept result.
