HERA: catches thousand-dollar drawing mistakes before the shop floor.

Could you build this?

No Automating engineering drawing and P&ID reviews requires specialized computer vision for technical schematics and deep domain knowledge of ASME and industrial standards.

What it would actually take: A production system must parse vector CAD files (DWG, DXF) and high-resolution raster blueprints to accurately extract dense technical annotations, geometric dimensioning and tolerancing (GD&T) callouts, and bill-of-materials tables. It requires custom optical character recognition and semantic graph representation of mechanical schematics matched against formal ASME and ISO engineering specification databases. Building this requires specialized computer vision researchers, CAD format parsing specialists, and licensed professional mechanical engineers to curate standards and verification rules.
