v1.10.0 — 3D Fillet & Manual Export

Highlights

3D Fillet (new)

Round edges on 3D meshes with fillet, complementing the existing chamfer:

(-> mesh (fillet :top 3 :segments 8))       ; Rounded top edges
(-> mesh (fillet :all 2))                   ; All sharp edges
(-> mesh (fillet :top 3 :blend-vertices true)) ; With spherical corner blend

Per-edge concave cutters with quarter-circle arc cross-section. Optional vertex sphere blending at corners where 3+ faces meet.

3D Chamfer improvements

• Continuous strip mesh for faster CSG (single mesh-difference)
• Turtle-oriented selectors: :top :bottom :up :down :left :right :all

Manual Export

Generate downloadable Markdown manuals with screenshots:

Python script for batch export with images:

python3 scripts/export-manual.py --lang en      # With screenshots
python3 scripts/export-manual.py --check        # Non-regression test

Other

• Improved capture scene lighting and camera framing for better screenshots
• New examples: multiboard connector, pipe clamp
• Shell API unified: :style keyword replaces separate functions
• Pattern tiling and decorated shell caps (voronoi, grid)
• fillet-shape, chamfer-shape for 2D corner operations
• capped shape-fn for loft cap rounding
