Bend

Bend selected loops by dragging control points on a guide curve.

Bend Demo

Bend is a modal tool. It fits a guide curve through each selected loop, drops a row of control points along it, and lets you reshape the geometry by grabbing and dragging those points directly in the viewport.

Hotkeys

Key Action
Mouse Move Hover / drag the nearest control point
LMB Grab the highlighted point / drop it
RMB/ESC Cancel the current drag, or cancel the operator
Space/Enter Confirm operation
V View-aligned motion (free)
X / Y / Z Constrain motion to an axis — press again to toggle Global/Local
Shift+X/Y/Z Constrain to the YZ / XZ / XY plane
Scroll/+/- Add or remove control points
O Toggle proportional editing
Shift+O Cycle proportional falloff
Page Up/Page Down Grow / shrink proportional radius
+/- (proportional on) Add or remove parallel rings
B Toggle pinned border points
Ctrl+Z / Ctrl+Shift+Z Undo / redo a control-point edit

Properties

Points

  • Description: Number of control points per loop
  • Type: Integer
  • Range: 3 to 24
  • Default: 3

Axis

  • Description: Constraint for control-point motion
  • Type: Enum
  • Options: VIEW / X / Y / Z / YZ / XZ / XY
  • Default: VIEW

Space

  • Description: Axis basis — Global (world) or Local (object)
  • Type: Enum
  • Options: GLOBAL / LOCAL
  • Default: GLOBAL

Parallel Rings

  • Description: Number of parallel-loop rings added on each side of the selected loops. Auto-added loops are dimmed and not grabbable, but still receive proportional spread.
  • Type: Integer
  • Range: 0 to 8
  • Default: 0

Proportional Editing

  • Description: Affect nearby control points (across selected loops) with falloff
  • Type: Boolean
  • Default: False

Proportional Size

  • Description: Radius of proportional falloff in world units
  • Type: Float
  • Default: 1.0

Falloff

  • Description: Shape of the proportional influence curve
  • Type: Enum
  • Options: Smooth / Sphere / Root / Inverse Square / Sharp / Linear / Constant / Random
  • Default: Smooth

Pin Border Points

  • Description: Keep open-loop endpoints fixed during proportional spread
  • Type: Boolean
  • Default: True

How It Works

  1. Each selected loop is sampled into a guide curve with evenly spaced control points
  2. Grabbing a point and dragging it reshapes the curve, and the loop vertices follow
  3. Axis keys constrain the drag to a line or plane; V returns to free, view-aligned motion
  4. With proportional editing on, neighbouring control points move together within the radius, weighted by the chosen falloff
  5. Parallel rings pull in adjacent loops so a bend can spread smoothly across a band of geometry
