ll these 12500 points.
Group 1 would represent the point located at 0, 5, 10, 15, 20 etc.
Group 2 - 1, 6, 11, 16, 21 etc.
Group 3 - 2, 7, 12, 17, 22 etc.
Group 4 - 3, 8, 13, 18, 23 etc.
Group 5 - 4, 9, 14, 19, 24 etc.
I can create the pattern but the selection of points are all the points in row 0 and then all the points in row 5 and so on.
I would like the selection of points to start at the bottom left, and sequentially continue to the right and then continue on the 2nd row (left to right & bottom to top). i am hoping the pattern i am trying to achieve is more understood with the quick screen capture I uploaded.
the end goal is to be able to select all the points in the grid that are in each pattern.
Thanks in advance for any guidance with this. …

te one of the boxes (kind of). Now I'm trying to set up the pattern, but I would like it to be random. I'm having trouble coming up with the actual algorithm, though.
I'm able to generate a list of items, randomly select some of them, and rotate them. I can also select the item after a rotated one and move it to the right.
However, I'm having trouble selecting all of the items after an item that's been rotated, and moving all of them.
Let's say I have a list of 15 elements and numbers 3, 6, and 7 are rotated. I would need to move numbers 4 through 14 (since it starts at 0) to the right by an x amount; numbers 7 through 14 to the right by a 2x amount; and numbers 8 through 14 by a 3x amount.
How should I go about doing this?
I'll add my current non-working setup. I should note that since I'm new, it probably looks horribly disorganized. Sorry about that.
Thanks!…
run the script I get randomly sized polylines infilling the grid (Capture 3). But if I only intersect both the horizontal and vertical contours I get the correct infill.
So I'm thinking this is a matter of merging the data correctly to input into the grid component but I cannot seem to figure this one out.
I've attached my definition, just needs reference brep to begin. Any help would be great!!…
can work your way to more complex geometries. Alternatively, a simpler study like a Ladybug solar radiation analysis may be all the you need to evaluate whether a given facet of your shape should be glazed or opaque.
In any case, I can recognize one major error in your file is that you have tried to add windows as HBSurfaces. For energy simulations, windows must always be assigned as sub-surfaces of base surfaces.

tions and that will be the end of it. I will not look for you, I will not pursue you. But if you don't, I will look for you, I will find you, and I will continue to ask the aforementioned set of questions. Good luck.

Question 1: How do I go about measuring the arc length of a parabola in Rhino? In a nutshell, I'm looking to accurately measure curve length in Rhino in this case using a parabola.
Question 2: Once I can measure the arc length of a parabola, how do I go about manually changing it to a specified length (Ex: If my arc length is 14, but I need it to be 24)? Followup question, is there a way to use a slider in Grasshopper to do this?
Question 3: Once I eventually am able to create a parabola of a specific arc length/curve length the next thing I'll be doing is to create a parabolic cylinder comprised of 6 inch squares (view image below for visual cue). Is there a way to change the scale of a parabolic cylinder while still maintaining the 6x6" grid/panels? I plan on using a 3D printer to print out 6x6" interlocking tiles that when glued will form a parabola, and would like to be able to do it for a variety of parabola sizes.

the catenary shape
6) Get the mid point of all the heaxgons
7) Create surfaces to get the average normal of each hexagons
8) Project the hexagon on the normal plane
9) Move the plane using the normals
10) create mesh faces between first and second hexagons
11) create mesh faces to close the planar hexagon
12) Orient all the mesh faces on a flat grid to laser cut them
13) Join and weld the mesh
14) Thicken the mesh using Weaverbird to get a shell
I hope this helps. It is all one mesh at the end made of quads on the side and triangles on the top (yes 6 of them).
All the best,
Arthur
