As the semester progressed, Rohan's friends and classmates began to notice his improvement. They would often gather around him as he worked on his designs, marveling at the precision and accuracy of his drawings.

It was a sunny day in Mumbai when Rohan, a second-year engineering student, stumbled upon an old bookstore in the heart of the city. As he browsed through the shelves, his eyes landed on a well-worn copy of "Engineering Graphics" by K.V. Natarajan. The cover was a bit faded, and the pages were yellowed with age, but the title seemed to leap out at him.

The book "Engineering Graphics" by K.V. Natarajan had become a legend among engineering students, a testament to the power of a well-written textbook to transform a struggling student's understanding of a complex subject.

Rohan purchased the book and took it back to his hostel room. For the next few days, he devoted every spare moment to practicing the exercises and problems outlined in the book. As he worked through the chapters, he began to feel more confident in his ability to visualize and draw complex engineering designs.
