d files have surface divided into rectangular grid, I want that grid hexagonal SO THAT I CAN ATTACH MY HEXAGONAL GEOMETRY IN IT.Hexagon Pattern.3dm,,,,Hexagonal Pattern.ghx…
I have a database with about 80 tables on it, so i wanna connect to the database, make 5/6 different queries, extract the info and use it as an input to grasshopper.
. The rules to dispatch the lines are the next:
I start with a list that alternate true/false; like that: true, false, true, false.
If the angles between those lines are greater than 89° I want to inverse the next part of the list:
True, False, True, False, True, False,...
become
True, False, [>89°] False, True, False, True, [>89°] True, False,...
I managed to create a true false list, to check for the greater than 89° angle, to separate the lines relatively to the angles, but I don't know how to inverse part of the list at certain index.
(In the picture, I have written 90° but it should be 89°, I check for greater than 89° and not equal to 90° because in the real rhino model, the lines won't be exactly orthogonal)
If you have another idea to to reach the same result, it's also okay, I tried to find rules to solve the problems, but I may have overlooked other solutions !
And if there is some part of the patch that are correct but there is easier solution, I would love to learn as I am still new to grasshopper.
Thanks for taking the time to read. :)

blinds be (B1,B2..B5). Then the geometry for the five iterations will be ((A+B1), (A+B2)...(A+B5)).
And assume that you are measuring illuminance at four points inside the room (x1,x2,x3,x4) and one point outside the room(y1).
The way Daysim works ( and should work as per the best of my understanding) is that for each setting of the blind (ie. B1,B2,..B5), a separate value of (x1,x2,x3,x4) gets calculated through the Daylight Coefficient Method. So let's say you have illuminance thresholds of (p,q,r,s,t) corresponding to (B1,B2,..B5). What the shade-control algorithm does is that it compares the illuminance at y1 with your threshold of (p,q,..t) and then chooses a value of (x1,x,2,x3,x4) on basis of that. So, when we repeat this process for (365x24=)8760 hours , we end up with a value of a shade setting for each hour which was set on basis of your threshold illuminance values.
I would have gladly answered your question on HB itself, however, I usually work with Daysim directly through commandline.
(BTW, if you are interested in reading more about Daysim google Christoph Reinhart's dissertation on the subject, along with some papers by Zack Rogers).…
