PeriTrace: Pattern Tracer
Transform real-world sewing patterns into precise digital patterns using augmented reality.
PeriTrace helps fashion designers, pattern makers, tailors, and sewing enthusiasts capture garment pieces and other flat designs directly from the physical world. Simply trace a pattern manually or automatically, organize your pattern pieces, and export them as industry-standard vector files for further editing, manufacturing, or archiving.
Features
• AR Pattern Tracing – Manually trace the outlines, seam lines, and marks of physical pattern pieces directly in augmented reality.
• AR Pattern Detection - Automatically detect the outlines and capture internal images of physical pattern pieces to speed up digitization.
• Pattern Organization – Store multiple pattern pieces in a single project. Move, rotate, and arrange pieces on a virtual workspace.
• File Export – Export your patterns as PDF, DXF, and SVG formats for CAD software, vector graphics applications, or manufacturing workflows. Exported files preserve the layout of your pattern pieces.
• Designed for Fashion Workflows – Digitize physical patterns without manually measuring or redrawing every outline.
