Hi @RameshAnbalagan !

Reading CAD PDF drawing documents can be tricky because they often contain a mix of text, vector graphics, and images. Depending on your goal, here are some options:

1. Extract Text (OCR)

If you want to extract text from the PDF (like dimensions or annotations), you can use OCR models:

  • Tesseract OCR: A free, open-source option for recognizing text in PDFs.
  • Azure Form Recognizer or Google Cloud Vision: More advanced cloud-based options for structured text extraction.

2. Understand Vector Graphics

To process the vector graphics or drawings themselves, try:

  • DeepCAD: A deep learning model designed for CAD drawings.
  • SVG or DXF Parsing Libraries: Convert PDF to DXF or SVG format and analyze them using CAD-specific libraries like ezdxf or svgpathtools.

3. Hybrid Models for PDF Analysis

For a combination of text and image understanding:

  • LayoutLMv2 or LayoutLMv3 (Hugging Face): Specialized for document layouts, including text and images.
    Hope this help! :blush:
