Draft check is a requirement for manufacturing processes that involves moulding, casting and Sheetmetal stamping. This implementation uses shader nodes to calculate the angle between the sub-division normals and the given direction.

  • Green Color: Positive Draft
  • Red Color: Negative Draft
  • Yellow Color: Areas between the positive and negative draft angle.

Draft Analysis Shader

  • Mix Overlay: Mixes between user shader and the Draft analysis shader
  • Direction: Die-draw or Drsft direction vector (default value: Z axis)
  • Positive Angle: Positive draft angle in degrees. (default value: 3 deg)
  • Negative Angle: Negative draft angle in degrees. (default value: -3 deg)
