I'm a student. I am looking for some book to practice.
Can you recommend a book, website with mechanical pictures(Rollers and other stuff with all dimensions) that I could try to model it in 3D?
Sorry for my english
Any good Drafting textbook is usually filled with examples like you've described and generally the older the better. For example, my old Drafting textbook was "Graphics: With an Introduction to Conceptual Design", by A. S. Levens (© 1962).
