The Case

Notch marks shouldn't take an afternoon.

The Problem

By hand, every time.

  • Hours spent measuring and drawing each mark
  • Inconsistent angles cause alignment errors
  • Seam allowances recalculated on every revision
  • Sharp corners easy to miss, hard to fix
The Solution

One command, every notch.

  • All marks placed in seconds — correctly oriented
  • Six notch types for every production standard
  • Variable seam allowances per edge
  • Smart corner detection skips conflicts automatically
