Curve

Extrude a 2D Blender curve object into an SDF shape. This bridges Blender’s native curve tools with Chisel’s SDF system.

Basic Usage

  1. Create a 2D curve object in Blender (must be closed splines)
  2. Shift+A > Chisel > Curve or use the Pie Menu
  3. In the Object Properties panel, set the Curve pointer to your curve object
  4. Adjust Depth to control the extrusion thickness

Parameters

Curve Object

  • Description: Pointer to a Blender curve object (must be 2D, closed splines)
  • Effect: Defines the cross-section shape

Depth

  • Description: Extrusion depth controlled via the Geometry Nodes modifier
  • Effect: Controls how thick the extruded shape is

Rounding

  • Range: 0.0 to 10.0
  • Default: 0.0
  • Effect: Rounds the extrusion edges

Profile

  • Options: Round / Sharp / Soft / Tight / Chamfer
  • Default: Round

Chamfer Smooth

  • Description: Rounds the sharp edges where chamfer meets the faces
  • Range: 0.0 to 5.0 (soft max 0.5)
  • Default: 0.0
  • Effect: Only applies when Profile is set to Chamfer

Requirements

  • The curve must be 2D (not 3D)
  • All splines in the curve must be closed
  • Uses an SDF texture grid internally (resolution set in Render Properties > Curve SDF Resolution)

Curve SDF Resolution

The global resolution for curve SDF textures is set in Render Properties:

  • Range: 32 to 512
  • Default: 128
  • Higher values give sharper edges but use more memory
