I'm an Architecture student who has to produce technical drawing as part of my course - many of which have to be hand-drawn. Although I've done engineering drawing before, I didn't know what the standards for architectural technical drawing were. Although this is a slim book, it's also quite cheap, AND the text is very small, so it packs a lot into the space.
The book covers many things, such as the standard type of lines, their width, infills and hatching, labelling and sections, fonts, plan headers and how to fold the finished drawing for posting. Each subject is given just enough words to transmit the information, making the book easy to dip into when you need to check a single piece of information.
The drawings are very clear and easily understood, and the text is direct and to the point and conveys information excellently.
As a reference book to refer to, every architect should have this book. It's slim enough to be carried to and from University easily, and it will be sitting next to my drawing board for many years to come.
