Pattern design
Trace a reference, close pieces, choose construction details, and print a pattern at the size you intend to build.
Native macOS pattern design
From reference to
workshop-ready pattern.
Trace a photo or sketch, plan your glass, and print at physical scale—using a private Mac app that understands real pieces.
A pattern you can build
Make decisions before the light table.
Glasswright turns drawn seams into pieces as you work, so the design, construction plan, glass plan, and full-size output stay connected.
Glass inventory
Measure a sheet with AR, trace its visible boundary, and share a local scan back to your Mac.
Quick answers
Frequently asked questions
Where are my patterns stored?
Patterns are ordinary .glasswright document packages saved wherever you choose. Glasswright does not require an account or cloud storage.
How do iPhone scans reach my Mac?
Save a .glassscan package on iPhone, then use AirDrop, Messages, Mail, Files, or another share-sheet destination you choose.
Are measurements and printed patterns exact?
iPhone measurements are approximate. For full-size patterns, use Glasswright’s printer calibration sheet and confirm critical dimensions before cutting glass.
Can I print on larger paper?
Yes. Glasswright supports home, ISO, architectural, and custom paper sizes, with single-sheet or tiled output at physical scale.
