I work in a manufacturing environment and I'm exploring whether AI/computer vision can be used to automatically interpret 2D engineering drawings.

The goal is to identify and extract:

* Components and geometric features

* Dimensions and their associated features

* Tolerances

* GD&T symbols

* Hole specifications

* Surface-finish information

* Engineering notes and annotations

Ideally, the output would be structured data that could later be used for manufacturing, inspection, costing, BOM generation, or integration with other systems.

I'm aware that OCR can extract text, but the bigger challenge seems to be understanding the **relationship between dimensions, symbols and the actual geometry/features in the drawing**.

Has anyone worked on something similar?

I'm particularly interested in:

* Vision-language models

* OCR + computer vision pipelines

* Object detection/segmentation

* Engineering drawing datasets

* CAD-aware approaches

* Open-source models or commercial APIs

What would be the most practical architecture for solving this reliably with real-world engineering drawings?

Hey Mumbaikars,I am a daily metro commuter looking for the best possible way to slash my monthly travel budget across the metro lines.I have already tried using Uber, BHIM, Rapido, Paytm, and Magicpin, but they are either not giving discounts anymore, have stopped cashbacks, or are completely dry for regular daily bookings.Please guide me: What is the single best working hack, app, pass, or trick you use to save the most money on daily metro travel?Are there any specific bank card reward loops, hidden apps, or pass combinations that actually save significant money right now? I am tired of paying full price or hunting for dead coupon codes.Would love your guidance and recommendations below. Thanks!
