GD&T analysis software for engineering drawings that validates designs against ASME Y14.5 and catches errors before production release.
F4 is a desktop-based GD&T analysis platform that processes PDF and STEP files locally without cloud upload. It validates GD&T against the ASME Y14.5 standard using a dedicated Drawing Validation Engine (no AI), performs interface stackup analysis, generates redlined drawings summarizing validation results, and exports to downstream formats including AS9102 FAIR tables and Model-Based Definition migration packages. Available in three tiers: F4 Review, F4 Pro, and F4 Enterprise. F4 is a product of F4 Industries.
