DeltaCAD         

is 2d only, but has a scripting language, works on Windows 8, I have not tried Windows 10 or 11. But these macros do not work on
Apple computers as DeltaCAD uses a different scripting language o
n Apple computers.

DeltaCAD's main web page is here
Carl Sabanski's DeltaCAD page is here


FREE DIAL MACROS ~ The  benefit of DeltaCAD is its scripting, and here are some of mine for horizontal and vertical dials for
north/south latitudes with longitude correction, the meridian dial both east and west, a horizontal dial with calendar lines, and an
equatorial dial, N and S plates, calendar circles and sunrise/set lines, a polar dial, shepherd's dial, and the winged azimuth dial. Play
with them and have fun, their suffix is ".bas". But also check out
NanoCAD and FreeCAD, free and programmable.

Note: FreeCAD is free and is programmable using Python, see my Python macros here.      

Note: NanoCAD is free, programmable using VBS, Java Script, and LISP. See my VBS and Java Script macros here.           

NOTE ~ I use my own abbreviations as I found no standard ones. h(horizontal), v(vertical), p(polar), m(meridian), z(azimuth),
q(equatorial), etc

DIAL NOMOGRAMS FOR HORIZONTAL AND VERTICAL DIALS,
NOTES, AND A DELTACAD MACRO FOR THEM, also covered are
the polar and meridian dial with calendar data, and for the vertical
decliner, SD, SH and DL. Notes show how to use SH and DL for a
surrogate horizontal dial, and thus avoid a much more complex
nomogram that would use the full vertical decliner hour line
nomogram.bas

Very good notes on nomogram are in the big book, as well as in the book that comes
with the big book as a download,
Supplemental Shadows which are excellent.
D e l t a C A D
for Windows not Apple
NOTE:    Most dial programs are collected together so a main menu selects a sub program.  

NOTE:   Many of the dials above including the Shepherd and Azimuth dials are animated ~  great education  
tool to see how hour lines, shadows, and calendar/declination lines move as latitude automatically steps up,
or to see how the shadow follows a calendar curve. The vertical decliner will also animate if dec set to 0, see
how hour lines, SD, and SH vary with declination.
Do not use animation mode if you are epileptic.

NOTE:   The calendar curves program can be used to draw calendar lines for any hour angle dial. The design
latitude for the "calendar curves" is the  
SH of the actual dial, and the "noon" line of the "calendar curve dial" is
placed on the
SD line of the actual dial. Pay attention to the SSL or GLH to make sure you are using the correct
distance. Pay attention to longitude correction, the best method is to use the calendar line points as angle
from SD and distance with no longitude correction, and transpose the results to the vertical dial's SD.  These
are tools, and are a good blend of applying knowledge using tools at the higher levels of learning, rather than
doing things by rote.   


HOW TO PROGRAM DELTACAD MACROS ~     

Programming Shadows also has code for certain dials in other languages so you may compare
programming languages, and techniques. Even covers the legacy languages! But wait, there's more - even
the legacy computers, with simulators I wrote that include assemblers, linkers, and executors for the included
sundial programs I also wrote for the IBM 1401 and IBM 360. My IBM 1401 and 360 simulators (written as GUI
in Lazarus - a Pascal open source implementation) I included tracing, core dumps, and instruction stepping,
etc.
