Use & Safety Notice

Current beta

PRE-FAB Workbench is a free browser-based drawing, conversion and geometry-checking utility. The current beta is available without an account or payment. Core drawing and file-processing operations run locally in your browser.

Product boundaries

PRE-FAB is in beta and may contain defects or be unavailable at times. It assists with drawing preparation, conversion and geometry checking.

PRE-FAB does not certify engineering safety, manufacturability or machine suitability. Automated checks are limited and do not replace independent verification.

Before fabrication

Check exported files, dimensions, geometry, materials, machine settings and the receiving CAD/CAM or manufacturing workflow before fabrication. Work involving engineering or safety decisions may call for qualified professional input.

Supervision

Fabrication equipment and processes can present risks. Young users should have appropriate adult supervision when using them.
