GD&T Analyzed for Clarity, Manufacturability, and Inspectability

GD&T Analysis

Without relying on AI, F4 analyzes every element of your GD&T to assess whether your design is clear, manufacturable, and production ready. When issues are found, F4 flags them and guides engineers toward resolving the problem. To make the drawing easier to understand, engineers can visualize their datums, reference frames, and tolerance zones that have been analyzed directly on the 3D model in F4.

GD&T Tolerance Analysis

F4 also calculates tolerance stack-ups instantly - directly from the drawing. All geometric controls, tolerances, and other relevant GD&T are taken into account in the stack path to provide min and max distances between critical features. Generated stack up tables can be exported for sharing as an excel as well. What once took hours of manual error-prone work now takes seconds.

GD&T Definitions

F4 automatically interprets all GD&T symbols, datums, and notes based on the correct standards - no more second-guessing or misreading intent. Everyone from design to manufacturing sees the same definition, keeping teams aligned and avoiding costly miscommunication.

GD&T Exports

After verifying that all tolerances are manufacturable and geometric controls are inspectable, F4 automatically generates pre-filled FAIR reports (including AS9102C) directly from the drawing - so QA and MFG engineers don’t have to waste time manually ballooning GD&T. For full visibility into analysis, markups, and comments, design engineers can share a .f4 export of their work with their team.

FAQ

Questions Teams Ask Before Rollout

Straight answers for teams evaluating the platform.

Is F4 a CAD System or a PLM?

Neither! F4 is an on-device hardware platform that uses 3D and 2D design files generated from CAD platforms as inputs. F4 accepts files from major CAD platforms: NX, CATIA, SolidWorks, CREO, Fusion 360, & Onshape. F4 itself does not create design files. Teams also use F4 to document relevant data and status for assembly parts and interfaces instead of spreadsheets. Teams use F4 to supplement the design release process before changing part & assembly maturity in their PLM.

Who Should Use F4?

Any industrial team that creates or works with engineering drawings should use F4! Industrial teams use F4 to avoid the risk of engineers creating and releasing non-compliant drawings. Using F4 also avoids the risk of non-design stakeholders like manufacturers, vendors, and internal teams of misinterpreting drawings. Industrial teams use F4 to get all stakeholders aligned to avoid costly scrap, rework, and wasted time.

What About Defense and Aerospace Programs?

Yes, F4 is able to support aerospace and defense organizations. Our DDTC and BIS compliance processes are guided by specialized export-control legal counsel to ensure we can appropriately manage defense- and aerospace-related work. F4 also maintains the necessary certifications and licenses required to operate within highly regulated industries.

How Does F4 Approach Security and Compliance?

F4 Industries is committed to upholding the highest standards of data protection, privacy, and intellectual property security. Our platform is built for enterprise use, engineered specifically to meet the needs of industrial teams, and operates locally on-device to ensure maximum control over sensitive information. We also support two-factor authentication (2FA) for secure access and integrate seamlessly with existing enterprise security frameworks. Our team partners closely with customer security and compliance groups before onboarding to ensure adherence to all relevant policies and regulatory requirements.
