this, you'll have no horizontal force at the roller, but you will have it at the pinned support. If you wouldn't, then the structure will be displaced.
Usually, in 2 dimensional structures, if you want to know if an articulated structure is isostatic (as opposed to hyperstatic, which is what you have right now) is to use the following formula:
b+c-2·n=0;
b being the number of bars, c the number of constraints you have and n the number of nodes. In your case: b=19, c=3 (displacements constrained in X, Z at your pinned support and only constrained in Z at your roller support) and n=11, so: 19+3-2·11=0.
I recommend you to download the app SW Truss, as it's very useful to check your results instantly.…
a specific domain, for example:
0.) 0 to 1 -----> 11 random values from 0 to 1 (0.245,0.678,0.36,0.78,.28,0.18........)
1.) 1 to 2 -----> 11 random values from 1 to 2 (1.26,1.36,1.01,1.68,1.26,1.96.........)
3.) 2 to 3 -----> 11 random values from 2 to 3 (2.96,2.45,2.78,2.56,2.98,2.10..........)
4.) 3 to 4 and so on where I have a data set containing 11 paths with 11 values and the values fall within the specific domain.
Like my post above I have the correct path but I need to feed it the correct seed to get different values for each number. I tried grafting a series similar to the last post but it scrambles my data. Thanks so much for the help!

I've attached a rh and ghx file. http://we.tl/ghsd0UTxji - wetransfer link. I'm guessing the trick is to correctly define the Range (R) / Domain in the Random component, so that the circles' radi can vary between the fixed and static domain of 10 or 12 or 14 or 18 or 20. Meaning that the radi can only be 10, 12, 14, 18 or 20 - and not, lets say.. 11, 13, 15, 16, 17 or 19 for that matter. Thanks in advance, i hope someone can figure it out, because i can't seem to find anything online about how to set up such as specific domain.

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. …

I get it. I have 11 and 18 as boundaries and 7 to always add 1
But it doesn t seemt to work with the Loop set to False.
Am I doing something wrong?
Thanks,
Dimitris
otate 9°, the second module 18°, the third 27°, etc. I can only seem to get all 11 modules to rotate the same... I know it probably has something to do with series but I can't figure it out. the screen shot shows the 11 modules rotating to the same degree and the drawing is a plan of what I am trying to accomplish. Thank you so much in advance!…

I am triangulating this surface. I want to select just the red vertices. As you can note, I just need the inner vertices of this surface. I could do it mannually, but if I want to change the mesh density later, I will have to pick all of them manually again later.
Can someone help me?
Tks
