Sunny Day! As many of you are aware, Valentin Hristov wrote an excellent DeltaCad sundial macro for a bifilar sundial that can be designed in any arbitrary position. This macro can actually be used to design 13 different sundials.
I have never attempted to write a macro and I thought a good way to start learning would be to modify an existing macro. So, with Valentin's help, I have made a couple of modifications to his bifilar sundial macro. There are two changes I have incorporated as follows: In the original macro there are three selections for the hour line time intervals. In the modified version there are seven. In the original macro there is one set of date lines that are integrated with the period selection. In the modified version the date line selection has been separated from the period selection. There are now six selections for the date lines as well as the original three period selections. If you would like to see what the new version has to offer scroll way down to the bottom of this page: www.mysundial.ca/tsp/deltacad_sundial_macros_vh_bifilar2.html If you would like to get this macro go to this page: www.mysundial.ca/tsp/deltacad_sundial_macros_vh.html I believe these changes have added additional flexibility to the original macro. It was a challenge to even modify a macro and get it working. It is a great learning experience if you have never programmed before. Give it a try. If you encounter any problems with the macro please let me know. And while you are visiting go to the spider sundial page to see Valentin's latest macro. Happy Dialling!
