The bestselling AutoCAD book—revised and updated!: It takes some practice to get handy with AutoCAD—and it doesn't hurt to have a good guide by your side to help get you through the rough spots. Updated to cover AutoCAD releases through the 2017 version, this new edition of AutoCAD For Dummies is an ideal companion when you're learning the basics of the popular software. Written by a former engineer and AutoCAD teacher, the book walks you through the basics of setting up projects and making simple drawings all the way up to creating 3D models. Beginning with an overview of the AutoCAD interface, drawing tools, and ways to adjust your view of your work, AutoCAD For Dummies offers easy-to-follow guidance on using straight and curved lines to manage properties, object selection, and creating layouts. Next, it shows you how to use advanced AutoCAD tools, including Blocks, Arrays, Xrefs, and Parametrics. Finally, you'll find out how to move your work in to the wonderful world of 3D modeling. Create an AutoCAD project from the ground up - Make and edit basic drawings starting with straight lines and curves - Jump into advanced drawing with 3D modeling - Find quick answers to your AutoCAD questions. It's true that AutoCAD is tough, but with the friendly instruction in this hands-on guide, you'll find everything you need to start creating marvelous models—without losing your cool.

This work provides an up-to-date overview of modern instruments used in earthquake seismology as well as a description of theoretical and practical aspects of seismic instrumentation. The main topics are: • Choosing and installing equipment for seismic stations • Designing and setting up seismic networks and arrays • Maintaining and calibrating seismic instruments. It also provides detailed descriptions of the following: • Seismic sensors • Digitizers • Seismic recorders • Communication systems • Software used for seismic station and networks. In this second edition, new seismic equipment is presented and more comprehensive sections on topics like MEMS accelerometers, sigma-delta AD converters, dynamic range discussion and virtual networks have been included.This book is primarily intended for seismologists, engineers and technicians working with seismological instruments. It combines practical “know-how” with sufficient theory to explain the basic principles, making it also suitable for teaching students the most important aspects of seismic instrumentation. The book also gives a current overview of the majority of instruments and instrument manufacturers on the market, making it easy to compare the capability of instruments from different sources. SEISAN software was used for several examples in the book. This widely extended seismic analysis software is freely available from the University of Bergen website. The content of this book draws on the authors’ (a seismologist and a physicist) combined experience of working in this field for more than 35 years.
