I would like to suggest that those who have not visited my web site may wish to do so. It is http://www.illustratingshadows.com
With the exception of the main book, which is discounted to members of NASS and BSS, everything else on the site is free. There are spreadsheets for vertical, horizontal, and declining dials, and spreadsheets to help evaluate the latitude of a store bought generic dial, as well as a spreadsheet to help do most of the hard work when calculating a wall's declination. Most of the tables in the main book were built with spreadsheets, and these are on the web site. There are extracts from the book, such as a "just build the thing" (Micro Shadows), "Build and understand a horizontal dial" (Simple Shadows), which is extracted and simplified from the main book. Free. Also extracts on CAD and VRML, declination lines, and paper cutout and paper pop-up dials. Also, articles on the intricacies of spreadsheets and some innovative ways of doing things. Feel free to look at and download the stuff that is there. And if so inclined, feel free to acquire the main book which is almost 300 pages. The main book is: Library of Congress Control Number: 2005900674 Simon Wheaton-Smith ISBN 0-9765286-1-4 -
