## Overview

This Streamlit app lets a user upload a drawing PDF and a CSV of expected tags, then checks required tag fields and presents a table plus a marked-up drawing. The single source file implements the complete workflow; the graph separates its main runtime responsibilities. The README is empty, so capabilities and relationships shown here are based on the excerpted app source only.

Main entry points: [`iso_drawing_checker_app_full.py`](https://github.com/idanram30-hub/iso-drawing-checker/blob/main/iso_drawing_checker_app_full.py) (App workflow)
