AI-Powered Engineering Drawing
to Standard DXF
Upload P&ID piping diagrams or instrumentation drawings. AI auto-selects the matching model, outputs editable DXF in 10 seconds.
The Problem with Manual P&ID Digitization
Manual tracing of P&ID drawings is slow and expensive
High Labor Cost
Manual tracing per P&ID drawing
costs NT$2,000 – NT$15,000
Long Turnaround
Engineers need
2–5 working days per drawing

Core Features
Dual-Model Recognition Engine
P&ID piping diagrams (20 valve/pipe/equipment classes) and instrumentation drawings (8 element classes). System auto-selects the correct v2 model based on uploaded image type.
No Charge on Failed Conversions
A confidence score is computed after each recognition. If it falls below the quality threshold (too few elements detected or too high a misclassification rate), credits are automatically refunded — so every charge yields a usable result.
LIDS Secure Authentication
Enterprise-grade SSO via LIDS (LocalIdentityServer) with OAuth2 PKCE Flow. Drawing data is AES-encrypted in isolated storage, with optional auto-deletion after conversion.
Conversion History
Full history of all conversion jobs and DXF results — re-download at any time for easy tracking and management.
High-Accuracy v2 Models
P&ID v2 model (149MB) trained on 11,003 high-resolution tiles covering hand-drawn and digital P&ID drawings. Instrument v2 model (50MB) optimized for industrial spec drawings, retaining high accuracy even on very small markers (< 20px).
Supported Components
P&ID v2 and Instrumentation v2 dual models, auto-routed by uploaded image type
AI Recognition Architecture
YOLOv8 Object Detection × Tile-based Inference × Standard DXF Output
Image Preprocessing
Input drawings are auto-converted to grayscale, contrast-enhanced (CLAHE), and denoised. Dynamically tiled into overlapping 640×640 tiles (80px overlap) based on drawing size to ensure complete recognition of elements spanning tile boundaries.
YOLOv8 v2 Inference
Each tile passes through the YOLOv8 model, outputting bounding boxes, class labels, and confidence scores. P&ID model covers 20 classes; instrument drawing model covers 8 classes. Both rigorously validated for model quality.
NMS Deduplication
Overlapping predictions across tiles are merged using Non-Maximum Suppression (NMS, IoU threshold 0.45) to eliminate duplicate detections. Produces a final component list in drawing coordinate space.
DXF Layer Output
Components are assigned to corresponding DXF layers (e.g. VALVE, INSTRUMENT, PIPE). Outputs an AutoCAD R2013-compatible DXF file with block insertion points aligned to original drawing coordinates — ready to overlay and edit in any CAD application.
