Pathstitch 1.0.0

First public build of Pathstitch — a native macOS CAD/CAM app for leathercraft & pattern making.

Install

1. Download Pathstitch-1.0.dmg below and open it.
2. Drag Pathstitch onto the Applications folder.
3. First launch is blocked by Gatekeeper (the app is ad-hoc signed, not Apple-notarized). To open it:
   System Settings ▸ Privacy & Security ▸ Open Anyway, then confirm.
   (Or in Terminal: xattr -dr com.apple.quarantine /Applications/Pathstitch.app)

Requirements

• Apple-Silicon Mac (M1 or newer), macOS 14 (Sonoma) or later. Tested on macOS 26.
• Self-contained — no Python/conda needed; the backend ships inside the app.

What's inside

• 2D sketching (line, circle, rectangle, text, pen) with snapping & on-creation dimensions
• Parametric fillet / chamfer (G1/G2, per-corner, drag-to-size, Enter confirms / Esc cancels)
• Trim tool (hover preview + click/drag), offset, stitch-hole generation
• Move/rotate/scale/mirror/duplicate, layers, convert-lines, patterning, paper-folding
• 3D STEP import + unfold to 2D nets
• DXF / SVG / PDF / PNG export, native .stch projects, Finder QuickLook & thumbnails
• Customizable keybinds, light/dark themes, ⌘K command palette, rearrangeable toolbar
