(without using AI for analysis!)
GD&T takes years to master, and even experienced engineers can interpret the same drawing differently. When design intent is unclear, issues tend to surface later in interface stack-ups, manufacturing, or worse, in the field where fixes become far more expensive.
We built F4 to address that.
F4 - The GD&T Analysis Platform for Engineering Drawings
Upload a drawing and 3D model and F4 analyzes the GD&T to assess whether the design is clear, manufacturable, and inspectable. Engineers can visualize datum reference frames and tolerance zones directly on the 3D model, instantly calculate stack-ups from the drawing, and identify issues before they become costly problems.
F4 also generates the reports teams need to move forward, including stack-up tables and FAI documentation.
All analysis runs locally on-device using deterministic algorithms, producing reliable results engineers can trust.
Watch the video below to see how it works.
To evaluate whether your designs are truly production ready, book a demo of the F4 Enterprise platform on https://f4.dev and see our full GD&T coverage.
