Overview

Pattern Editor is a vector drawing tool built specifically for sewing and cosplay patterns — draft panels from scratch, add seam allowance and notches, mark grain direction, and export straight to print or to a cutter.

It opens on a blank canvas rather than an upload step: start a new project and you're drawing immediately.

See Getting started for the first-run workflow, or jump straight to Keyboard shortcuts if you just want the reference table.

What it's for

• Drafting pattern panels by hand, with precise shapes, curves, and snapping
• Adding construction detail a plain vector editor doesn't have: per-edge seam allowance, sewing notches, foam bevel compensation, and grain-direction labels
• Everyday vector editing you'd expect from Inkscape or Illustrator: copy and paste (even between patterns), duplicate, flip, nudging with the arrow keys, breaking and joining paths, and SVG import that keeps curves editable
• Exporting to a print-ready SVG, or straight to a laser cutter/CNC via DXF — with text converted to plain shapes for cutters that can't use fonts

Where to go next

1. Getting started

   Draft a panel, add seam allowance, and export it.

2. Canvas navigation

3. Drawing tools

   Every tool in the tool rail — shapes, the pen, text, pattern labels, darts, and the True Up tool — plus copy/paste, flipping, path node operations, and the right-click menu.

4. Seams & finishing

   Seam allowance, notches, corner rounding, offset paths, foam bevel compensation, and live symmetry — the pattern-specific half of the app.
