What EDS recognised on one drawing, what it refused to decide, and why.

Demonstration project - no figure here describes a real facilityChanges are not saved

Why

Recognition figures are from the project's own drawings, which EDS generated. They are regression evidence, not an accuracy claim about any real drawing.

Writes are validated against the engineering rules and then refused, because no database has been configured for this environment.

Findings on it

Three things EDS will not decide for you

A crossing is not a connection: two lines meeting on a sheet are usually not joined. A tie is a refusal: where two symbol candidates score equally, nothing is chosen. And a drawn boundary is never an approved system boundary - a dashed box is a drafter’s annotation, and promoting one is how a test pack comes to contain the wrong valves.

Raster recognition is capped at 60%. Why

The legend is evidence, not decoration

Where a drawing carries its own legend, the legend corroborates a symbol reading and raises its confidence - to a ceiling, never to certainty. A customer whose legend draws a globe valve the way everybody else draws a gate valve is not wrong; their drawing says what their legend says.
