There are four or five programs each with its own strengths. Personally, I
found François Blateyron's Shadows program to be very useful because he has
an option to print out Cartesian coordinates of the lines in tabular
form. Rather than using actual angle values, which are somewhat difficult
to lay out on a wall if you are up on a tall ladder, I used the table of
x,y coordinates of the solstice and equinox values for the lines and laid
them out precisely onto a sheet of masonite. I then drilled holes at
appropriate points on the lines and hoisted the masonite, stiffened with a
wood brace up the wall into position. While it was suspended there, I used
it as a template to transfer the layout holes onto the bricks with a
masonry drill.

Hi Everyone,
I am working on another vertical declining dial with large
declination like the one shown on page 95 of Waugh's book. I am looking
for a computer program or spreadsheet that would give me the hour line
angles from the sub-style and from vertical like Table 10.4 on page 95.
I thought I had a program that did that but I cannot remember. Is
there a program that prints out those angles?
Thanks in advanced,
