Why Fretwork Generator?

Modeling complex geometric screens, perforated facades, Arabic Mashrabiya patterns, or organic cellular panels by hand is notoriously tedious and creates messy boolean topology.

Fretwork Generator is a specialized, production-ready parametric system built directly for Blender. It produces manifold CAD-quality meshes with independent frame thickness, stepped strut ledges, automatic parameter recall upon selection, interactive 3D eyedropper attractors with per-panel isolation, and live deformation on planar faces and curved 3D architectural surfaces alike.

9 Parametric Pattern Engines

  • ›Voronoi: Organic cellular mesh with Lloyd's relaxation and smooth corner filleting.
  • ›Islamic Star (Girih): Authentic contact-angle construction (Kaashi/Hankin method).
  • ›Mashrabiya Star: Traditional 8-point geometric star lattices.
  • ›Hexagons / Honeycomb: Hexagonal packing with stagger and random omission.
  • ›Perforated Circles: Circular cutouts with aligned grid or staggered row offset.
  • ›Triangles: Alternating isometric triangular lattice.
  • ›Triweave (30°/90°/150°): Three-family intersecting strut weave.
  • ›Continuous Lines: Parallel slits with custom cut width and bowing.
  • ›Grid & Brick: Rectangular cutouts with corner radius and running bond offsets.

Eyedropper Attractors & Per-Panel Isolation

Modulate cutout density, gradient opening sizes, and organic flow using standard Blender objects:

  • ›Interactive Eyedropper Picker: Click Pick Point or Pick Curve to pick any Empty or Curve in 3D space with a real-time floating name HUD.
  • ›Auto-Parenting: Attractors auto-parent to their target panel so moving or rotating the panel moves all attractors with it seamlessly.
  • ›Per-Panel Isolation: Attractors assigned to Panel A exclusively affect Panel A — other panels remain completely untouched.
  • ›Advanced Taper Profiles: Constant, Linear, Smooth, and Center-Pinch taper profiles along Bézier curve arc-lengths.
  • ›Invert Mode: Make holes grow larger near attractors instead of shrinking.

Curved 3D Surfaces & Geometries

Generate panels onto any geometry with zero manual unwrapping needed:

  • ›Flat Standalone: Set width, height, and border margin directly in the panel.
  • ›Arbitrary Faces & N-gons: Select any flat face or multi-face region (including disks with inner holes).
  • ›Non-Coplanar Curved Meshes: Generate fretwork directly onto 360° cylinders, domes, and curved architectural walls with automatic longitudinal seaming and conformal UV mapping.

Direct Laser & CNC SVG Exporter

Export clean 2D vector profiles ready for CNC routers, laser cutters, and plasma cutting:

  • ›Pure 2D Projection: Automatically unrolls 3D/curved panels into flat cut sheets.
  • ›Projection Alignment: Choose between Auto (Panel Plane), Top (Z), Front (Y), or Side (X).
  • ›Industry Units: Export in millimeters (mm), inches (in), or pixels (px) with 1:1 scale accuracy.
  • ›Cut Modes: Laser Hairline (0.1mm cut paths), Filled Solid, or Combined.

Additional Workflow Highlights
