solution. Many thanks
Attached please see the sketches and files. So basically I have 1. arrayed the diamond plate in a rectangle and add a 4. curve attractor to achieve a dynamic result when I change the number slider.
The problem I am currently encountering is the 2. rotation constraint. I would only like to allow back and forth rotation for each plate not larger than let say 30 degree angle perhaps. (will be amendable later on)
And the plate will not rotate at 360 degree itself when changing the attractor parametric value.
So when the parametric value changing, the plate will only respond within its rotation constraint.

the use of digital technologies as architectural design tools. The workshop " Computer Aided Design: parametric design and digital fabrication " aims to do some introductory teaching in the use of some of these tools.
The workshop will focus on the use of computational models of parametric behavior for generating architectural forms. The generative capacity of these models it will be tested in the development of designs defined by repetitive non-standard components, based on the parametric control of its variations and series differentiations. This process will be developed by the use of a three-dimensional modeling software - Rhinoceros, associated with an application for visual programming - Grasshopper.
The last day of the workshop is dedicated to the use of digital manufacturing tools in architecture. Part of the work will take place at the facilities of the Institute of Design of Guimarães (IDEGUI) providing for the use of their laboratories and manufacturing CNC machines (computer numerically controlled).
At the end of the workshop, it is intended the students to understand that the use of digital technologies in architecture can overcome representational functions, and their integration in the design conception, analysis and construction enriches the methodology of project development.
Terms & Participants
The workshop will take place at the School of Architecture of the University of Minho (Campus Azurém, Guimarães) and the Institute of Design of Guimarães (Couros, Guimarães).
The workshop is pointed at students who attend the 3rd year and 4th year from MiArq, EAUM.
The maximum acceptance is 20 students and a minimum of 10 students.
Deadline for entries is April 11 and must be performed by eaum.pac@gmail.com.

you may know, PCS (from now I will call polar coordinate system with PCS, and cartesian one with CCS) describes point position with 2 values (like x and y in CCS) which are r and theta(r,theta). r is for distance from PCS center, theta is angular dimension which is in 0 to 360 or 0 to 2*pi domain.
To hark back to David's guide line - here it is replaced with guide circle.
Why to sort points like this ? As usual, one image tells more...
Here is logic behind all this stuff :
Find an average point of all given points*
Search for furthest point from an average point*
Create a circle with center at average point and radius = distance from average point to furthest point*
*Steps 1-3 can be replaced with custom hand-made circle, I decided to automate it that way.
For each point find closest point on circle - this will be used for finding theta value
For each point find distance to average point - this is r value
To overcome problem with same theta (t) values (like same x values in CCS), instead of multiplying by 1000, we will use a new create set component. This component creates set of integers, each one representing one unique input value. So if points A, B, C, D, E are (r,theta) :
A (1, 30)
B (2, 30)
C (3, 30)
D (1, 45)
E (1, 60)
Then create set will output list of integers = 0,0,0,1,2 (same theta for A, B, C other theta for D and E). Now its getting really easy - remap r values to domain 0 to 0.5 (or any less then 1), and add integers from create set component to remapped r values.
7. So what we have now is list of floating point numbers : A=0, B=0.25, C=0.5, D=1, E=2
Profit of remapping is that r values will never affect integers representing theta values - and all the information is stored in one floating point number ! By sorting these values we will obtain proper order of points - to complete this, we need to sort points parallel with values.
What's really cool about polar sorting - there could be any amount of points, but polyline connecting all of them will never self-intersect. Probably there is some relation with 2d convex hull.…
izing strength/spring stiffness and even the unit of your 3DM file setting.
sometimes the same pattern that can be planarized in one file would stop working once something else is modified. and sometimes the force can't even planarize one single cell.
I think you can find some idea from the following post:

'Reply by Daniel Piker on December 17, 2013 at 10:25am
Making the faces of a polygonal mesh planar is not always possible without dramatically changing the shape of either the polygons or the surface.
When the target surface has only positive Gaussian curvature it makes things somewhat easier, but the surface in your file also has regions of negative Gaussian curvature.
To approximate a surface of negative curvature with a discrete mesh, we need the angles around some of the vertices to sum to less than 360°. This is impossible to do in a mesh with 3 hexagons around each vertex without making some of these hexagons non-convex.
There are a few possible approaches, but I would say how to automatically cover an arbitrary surface with nicely shaped planar hexagons is still an unsolved problem.'
I have uploaded some test files for you to look at. …

thisthe errorthat appen when i lunch E+ with only one zone....what is going on???? …
to do once I figured out how you use only a small portion of each of my generated curves to make the 360 degree Loft surface. I had a huge AHA! moment when I realized the complete Loft surface really only needs a small portion of the generated curves rotated around to form a closed (except for top & bottom) surface. That is a major new insight for me and I appreciate you pointing it out.
I also tweaked the Twist angle parameter a bit so the resulting positive and negative Twist surfaces, when combined, yielded a result that was closer to my original shape. This is when I discovered something very interesting.
When I baked/exported the result using just one of the 2 twisted surfaces I got an STL file that had no errors, that 3D Builder was able to simplify from a 37 MB file to a 3 MB file, and that sliced A-OK. But, when I combined the left and right twisted surfaces, I was back with my same set of problems: the exported STL file had many errors, could not be fixed, and did not slice properly.
I went back to my original layout that uses the complete set of generated curves to create the Loft surface and found I got exactly the same results - using only one twisted surface worked fine, but nothing worked when the left and right twisted surfaces were combined. By nothing I mean I tried all the standard methods (GH Join and Sunion, Rhino Solid/Union, Join, etc.) What I think this means is that the Loft surface behaves the same, and apparently is the same, regardless if it is generated by rotating strips or by using complete closed curves.
Furthermore, I am guessing the problems with the combined/exported STL file made from both left and right twisted surfaces has to do with overlapping/coincident parts of each one - like the top & bottom planar surfaces and some of the wiggly parts.
If I am correct about this then it suggests to me that there is some sort of glitch in Rhino's STL Export function. This is surprising to me since I though an STL file only paid attention to the external shape of thngs,and did not know or care about any inside stuff. Of course this is all conjecture on my part, but at least for now seems it will be impossible for me to actually print the double-twisted geometry.…

he process. The last one is there because fixing it would cause another problem, which we feel is more serious. Solutions may well be forthcoming in the future though.
1. Grasshopper curves and points are drawn more towards the camera than they really are. This is a conscious decision. Often Rhino geometry and Grasshopper geometry exist in the same place. If we would draw the Grasshopper preview in place, then there's no telling whether you'd see the Rhino curve or the Grasshopper curve. We feel it's important that you always see the Grasshopper curve on top. This is why we draw all curves and points slightly towards the camera. However we don't do this for meshes. This results in something akin to the image below. The eye represents the location of the viewport camera, the shaded box represents the actual location of the geometry and all the thick black lines represent the edges of the geometry moved towards the camera. As you can see, the red lines will be visible, even though they should be behind the shaded box. This effect can get very strong when the camera is close to some geometry relative to the size of the boundingbox of all geometry.
2. Wires behind the camera are sometimes visible. This is a bug I don't know how to solve. We'll get around to it eventually. When an object is behind the camera the display transform sometimes makes it visible in front of the camera in some weird inverted perspective mode.
3. Meshes are not z-sorted prior to display. This means that the order in which they are drawn is not back-to-front, but fairly arbitrary. This means that a transparent mesh may appear to punch a hole in the mesh behind it. If this is annoying you to no end, you can use Ctrl+F on the Grasshopper components that contain the meshes that are punching holes and then press F5 to recompute. The draw order should now be different. Of course sometimes it will only 'fix' it for a specific camera angle.
