Upload a technical-drawing PDF to Imnoo's drawing analysis and return every inspection characteristic it detects — dimensional tolerances (⌀50 ±0.05, 12 +0.2/-0.1), ISO fit classes (H7 drills, g6 shafts), threads and fine threads, geometric tolerances (GD&T frames) and surface finishes (Ra/Rz) — each with a feature id, value, PDF page, position and the balloon number printed on the drawing when there is one, plus the title block (drawing/article number, material, general tolerance). Analysis takes roughly 20–120 s; the call waits up to timeout_seconds and otherwise returns status "processing" with the drawing_id to resume with. analyze_drawing uploads the PDF to Imnoo's drawing analysis (the service behind the web app): 1 free analysis per day per IP address, more when signed in; uploaded files are deleted automatically after a short retention period and nothing else is stored. Use save_analysis_to to keep the analysis JSON for offline reuse with load_analysis.

Open a drawing analysis JSON saved earlier (analyze_drawing with save_analysis_to, or the Imnoo FileStore analysis document) and register it as a drawing for the plan and export tools. Fully offline — no upload, no daily credit. Pass pdf_path as well so the drawing exports can draw on the original PDF and write next to it.

Turn an analysed drawing into the quality control plan the documents will print: one row per characteristic with its balloon number (numeric, padded or type-prefixed; printed drawing numbers kept by default), acceptance limits computed from nominal ± tolerance (dimensional tolerances only — fits, threads, GD&T and surface finishes are judged with gauges), the default measuring instrument per type, the inspection class/rate, and the section order. Deterministic and offline: adjust the plan options and call again until the plan is right, then pass the same options to the export tools.

Write the quality plan as the "Measurement and inspection report" workbook (.xlsx): headline with the inspection class, header block (article name, ET-No., batch number, inspection rate), the visual-inspection checklist (a–e), the dimensional-conformity table (Insp. dim. no. · nominal dimension or thread size · tolerance range · measuring instrument · actual dimension · deviation · date · inspector), change-tracking footnotes and the special-release/signature block — cell for cell the report the Imnoo calculator produces. Default location: next to the drawing PDF as _.xlsx.

Write the inspection PDF. variant "package" (default): the original drawing pages with translucent boxes on every selected characteristic, numbered balloons and optional leader arrows, followed by the printed plan (general-information form, feature table with colored number chips, instrument and sample fill-in lines, acceptance criteria and result checkboxes, final approval). "ballooned": the marked-up drawing pages only. "plan": the plan document only (no drawing pages, no PDF needed). The source PDF is never modified. Default location: next to the drawing PDF as _inspection-package.pdf / _ballooned.pdf / _quality-plan.pdf.
