Hera automates design review for mechanical drawings by checking GD&T conformance against ASME Y14.5-2018, code compliance against ASME BPVC/B31/AWS, tolerance stacks across sheets and interfaces, and drawing integrity for datums and contradictions. Backed by Y Combinator (Summer 2026), it reduces multi-day manual reviews to minutes. Engineer-to-order manufacturers in aerospace, medical devices, and pressure vessels use Hera to catch thousand-dollar errors before they reach the shop floor.
Hera offers an automated drawing review service that significantly enhances the efficiency and accuracy of mechanical design processes. The main features of their product include:
GD&T Conformance Checking: Hera verifies geometric dimensioning and tolerancing (GD&T) against the ASME Y14.5-2018 standard, ensuring that designs meet industry specifications.
Code Compliance Verification: The service checks for compliance with various codes, including ASME BPVC, B31, and AWS, which is crucial for industries such as aerospace and medical devices.
Tolerance Stack Analysis: Hera analyzes tolerance stacks across sheets and interfaces, helping to identify potential issues before they reach the manufacturing stage.
Drawing Integrity Assessment: The platform ensures the integrity of drawings by checking for datums and contradictions, which can lead to costly errors if overlooked.
Time Efficiency: By automating what traditionally takes days of manual review, Hera reduces the review process to mere minutes, allowing engineers to focus on more critical tasks.
Error Prevention: The service is designed to catch thousand-dollar errors before they reach the shop floor, ultimately saving costs and improving product quality.
Hera's offerings are particularly beneficial for engineer-to-order manufacturers in sectors like aerospace, medical devices, and pressure vessels, where precision and compliance are paramount.
