3 Useful Layouts
For Fun and Function
About the Author
-
A few years before Don Spencer ended his career as a propmaker (official
title of movie carpenters,) he was embarrassed to find out that he did not know
how to layout an arched doorway when all that was given was the size of the
door. So, he made sure to seek out the formula for deriving the radius of an
arc when only the height and width were given. When he retired, and sometime
after he published his informative book on door fixes, Door Trix,
Mr. Spencer decided to put out another book explaining not only the arch formula, but also
that of a right angle and several approaches to the ellipse. Hence, 3 Useful
Layouts.
