Hera catches thousand dollar errors before they hit the shop floor.
Last verified:
Every custom part starts as a 2D drawing, and every drawing has to be reviewed before manufacturing begins. Today that means senior engineers checking dimensions, tolerances, and GD&T callouts by hand against ASME and ISO standards. It takes days, it bottlenecks release, and errors still slip through to the shop floor, where they become scrap and rework. Hera automates design review. Upload a drawing, get back every violation with the standard it breaks and where. Engineer-to-order manufacturers in aerospace, medical devices, and pressure vessels use Hera to release drawings faster and catch mistakes before they cost real money.
