PN Engineering Datasets
README – Professional Documentation
--------------------------------------------------

Thank you for using PN Engineering Datasets.
This dataset contains real reinforced concrete (RC) engineering drawings
created by a professional structural engineering office with 15+ years of experience.

--------------------------------------------------
1. Purpose of the Dataset
--------------------------------------------------
The dataset is designed for:
• AI/ML training (OCR, Vision, multimodal LLMs)
• Structural engineering education
• BIM automation development
• CAD/drafting learning
• Civil engineering research
• Dataset benchmarking

--------------------------------------------------
2. Dataset Structure
--------------------------------------------------
/01_PDF/   
    Cleaned, flattened, anonymized PDF drawings

/02_PNG/  
    High-resolution PNG (1200 DPI) versions

/03_Documentation/  
    DATA_DICTIONARY, DATASET_INFO_TEMPLATE, DATASET_STRUCTURE_BLUEPRINT, JSON metadata, License, README

--------------------------------------------------
3. File Formats
--------------------------------------------------
PDF:
• Flattened  
• Metadata removed  
• OCR-friendly  

PNG:
• 1200 DPI  
• Clean background  
• High contrast  

--------------------------------------------------
4. Usage Guidelines
--------------------------------------------------
You MAY:
• Use for internal commercial AI training  
• Train OCR/CV/LLM models  
• Use in academic or enterprise research  
• Build derived datasets/models  

You MAY NOT:
• Redistribute or resell raw files  
• Upload raw drawings publicly  
• Claim authorship of the original drawings  

This dataset is suitable for commercial use inside your own tools, 
models, or research workflows. Redistribution of the dataset itself 
is not permitted — see LICENSE.txt for full details.

--------------------------------------------------
5. Software Compatibility
--------------------------------------------------
The dataset works with:
• Python, OpenCV, Tesseract, PIL  
• PyTorch / TensorFlow  
• Roboflow  
• All major OCR/CV frameworks  
• Engineering & BIM automation tools  

--------------------------------------------------
6. Notes
--------------------------------------------------
Not intended for real construction use.  
Provided strictly for research and training purposes.

----------------------------------------------
7. SUPPORT
