Does anyone know of any good guides/tutorials for making parts from 2d drawings that are a little more advanced?

I'm trying to get better at reading drawings and making parts from the drawings, it can get confusing when there are so many lines and numbers so I was wondering if anyone knows of any good guides/tutorials or even some good drawings to practice with. I can find plenty of beginner stuff but i'm hoping to find some that are a little more difficult. Thanks!
