Models

Step 1 sends drawing crops, so it needs a model that can see them. Steps 2 and 3 send step 1’s readings as text — a text-only model with a large context is a fair answer there.

Plan10 objects · 25 measurements · 11 notes · 13 labels

This crop shows an existing track alignment plan for the Central of Georgia Railroad Company at the SR 21 bridge crossing. Dashed rectangular limits identify left and right bridge extents, with B.F.P.R. bent locations at each end and begin/end bridge stations. A partial surveyed top-of-rail elevations table is visible at the lower right, but its right-hand columns are cropped.

Every item from step 2 compared against the project’s engineering ontology, and then, for each one that lands in a class, a take-off of what that class asks for. The class list goes up as a closed vocabulary, so regional wording resolves without a synonym table — BENT to a pier system, PSC BEAM to a prestressed girder. Any class id that is not in the ontology is rejected rather than stored. The take-off reads every crop behind an item, derives what the drawings imply, shows its arithmetic, and says plainly when a number is not there. Matching against bridge v1.0.0, 133 classes.

78% of items placed. The 5 below fit no class — add one to the ontology and match again.

◈Index for the agentnot indexed · 192 points ready

Everything steps 1 and 2 know, written to the vector store for a chat agent to answer from. Cut fine — a point for each object, each measurement and each note, not one per crop — with the page, the crop and the drawing written into every one, so a retrieved number arrives with enough context to be an answer. The readings as a whole and step 2’s items are indexed too, for the questions that are about a drawing rather than a figure.

Re-runnable at any time: each point is keyed to the record it came from, so re-indexing replaces what changed, adds what is new, and drops what the drawings no longer support. Re-read a crop or correct one by hand, then press this.
