Designed for introductory AutoCAD users, Discovering AutoCAD 2020 presents a hands-on, activity-based approach to the use of AutoCAD 2020 as a drafting tool--complete with techniques, tips, shortcuts, and insights that improve efficiency. Topics and tasks are carefully grouped to lead students logically through the AutoCAD command set, with the level of difficulty increasing steadily as skills are acquired through experience and practice. Straightforward explanations focus on what is relevant to actual drawing procedures, and illustrations show exactly what to expect on the computer screen. This edition features updates for the latest release of AutoCAD 2020, projects, and test questions for each chapter. Lessons are broken down into tasks listed at the beginning of each section, introducing students to the AutoCAD commands using a structured, intuitive approach and helping students anticipate what information will be needed at each new phase of the learning process. General Procedur

Behind the scenes, stories, jokes and analysis of all the Monkey Island games, including many interviews of the creators. LucasArts has become a legendary developer in part because of The Secret of Monkey Island, which was created here in 1990. The Secret of Monkey Island, the world's most famous point-and-click adventure game, owes its reputation to its world of colourful, delightfully anachronistic pirates, to its Monty Python humour, but also, quite simply, to the fact that it revolutionised a genre. This book is a tribute to the adventures of Guybrush Threepwood, the great pirate. But it also aims to explain why Monkey Island represents a decisive step forward in the way a story can be told through a video game. It will also look back at the turbulent history of LucasArts and Telltale Games, discover a few recipes for voodoo toddy, learn interactive pirate reggae songs, shine at a social gathering of forty-something geeks and discover lines as sharp as a boarding sword (useful for
