Industrial drawing analysis large model
SCENE · Machining/Technology · Drawings and BOM
Engineering‑grade intelligence for 2D/3D models: covering mainstream formats such as STEP / IGES / DWG / DXF / PDF, it supports part/feature recognition, cross‑drawing part similarity, version diffs, rule checks and computation outputs. Built for low error, reviewability, traceability and regression—every conclusion comes with evidence and process traces (not black‑box summaries), and integrates with downstream MES / PLM.
Five-step pipeline
- Layout analysis: Picture frame, title bar, details bar partition; handle scanning distortion and multi-page PDF.
- information extraction: Table and annotation text structuring; units and tolerance regularization.
- symbol recognition: Geometric tolerances, roughness, welding symbols, etc. are analyzed according to national/enterprise standard templates.
- Pattern analysis: View relationship, sectioning and local magnification index; key dimension chain extraction.
- Manual verification: About 10% of the random inspection interfaces focus on low-confidence fields to avoid heavy work for all employees.
Core indicators (project actual measurement interval)
| Review preparation hours | Compared with the original process, the maximum80%Decrease (industry related to image file complexity) |
| Dimensions and parameter extraction | In a stable production line scenario, the accuracy rate can reach95%+ |
| Traceability | Field → Element Bounding Box → Original document page number link remains intact |
The above picture comes from the existing delivered materials and is used to represent the interaction form of "extraction results + artificial focus".
Format and interface
Input side compatible with PDF,DWG, DXF, high-resolution raster images, andSTEP, PRTand other 3D CAD formats; the output side supports JSON, tables and configurableCSV, and expose the difference comparisonAPIfor change management.
Deployment and hardware
| project | suggestion |
|---|---|
| reasoning | GPUVideo memory ≥ 16 GB (single task concurrent benchmark) |
| storage | Versioned image file warehouse supports audit mode of only adding but not changing |
| network | Intranet offline inference is optional; update packages can be delivered via the bastion host |
