The GD&T Analysis Platform for Engineering Drawings
GD&T takes years to master. Engineers must encode their design intent into a dense syntax that manufacturers must decode, and not everyone gets it right. Put ten engineers in front of the same drawing and you may get ten different interpretations. Which means errors often surface later in interface stack-ups, manufacturing, or in the field - when they’re far more expensive to fix. That’s why we built F4 - the platform that analyzes GD&T to determine whether your designs are ready for production. Drop in your drawing and 3D file. F4 analyzes every element of your GD&T to assess whether your design is clear, manufacturable, and production ready. To make the drawing easier to understand, engineers can visualize their datums, reference frames, and tolerance zones directly on the 3D model. F4 also calculates tolerance stack-ups instantly - directly from the drawing. What once took hours of manual work now takes seconds. When issues are found, F4 flags them and guides engineers toward resolving the problem. After analyzing your drawing, F4 also automatically generates design and inspection reports - stack-up tables, FAI reports - ready to share with your team. And it does all of this locally on-device with no AI used for analysis. Producing deterministic results engineers can trust.
F4 Industries offers a GD&T analysis platform that analyzes geometric dimensioning and tolerancing on engineering drawings, providing visualization on 2D/3D models, tolerance stack-ups, and automated FAIR reports. It emphasizes on-device processing without AI, with tiered pricing and on-premises-like capabilities for regulated environments.
The platform accepts CAD-derived drawings and supports major formats (NX, CATIA, SolidWorks, CREO, Fusion 360, Onshape). It analyzes every GD&T element, visualizes datums, reference frames, and tolerance zones on the 3D model, and computes tolerance stack-ups from the drawing. It automatically interprets GD&T symbols, datums, and notes to align all stakeholders, and can generate pre-filled FAIR reports (including AS9102C) with export options (.f4) for team sharing. Pricing tiers (Lite, Pro, Enterprise) unlock progressively more features such as core analysis, tolerance analysis, sharing online, expert access, private releases, and rollout support. The product operates locally on-device to support regulated environments, with security features and compliance provisions for aerospace/defense contexts.
Who it’s for: Industrial teams that create or work with engineering drawings, including aerospace/defense and manufacturing, requiring GD&T analysis, manufacturability checks, and compliant reporting.

We help hardware teams 10x how they redline & interpret engineering drawings
F4 offers a platform that treats engineering drawings as code, automatically validating GD&T dimensions and symbols against ASME/ISO standards in real time. It targets hardware teams to reduce noncompliance, scrap, and miscommunication by providing instant compliance scoring and automated correction recommendations during the drawing review process.
