s. Now ... I want from you to do the proper combo of columns for the job: I want a dynamic solution worth the name not some stupid columns going vertically. Use the tree regions in order to avoid distorting the glass modular floor. Say like this:
The truss must engulf the trees. Killing a tree is a crime (even touching it should be a crime). How to do it? Same for the rotating fins. Assembling the truss must take provision of the branches (if they are fragile).
Plaza must being divided as follows: a perimeter ring (critical) separates the glass floor panels from the ugly buildings AND the tree regions. Fine grey pebbles are OK for that. Then the panels deploy in the remaining region. Panels must be all the same: 90*90cm. Solve this "arrangement" with GH. Measure the drainage slopes and calculate the Buzon pedestals with GH (how far we need to adjust them: critical for ordering).
Cover the existing pavement with a 5cm thick layer of black pebbles (bonus: hide the cables for the led arrays and the rings [no WiFi required]). Create variations of these arrays in GH.
Create something for servicing the whole thing.
Greenhouse effect can raise the temperature below the glass flooring (BTW: panels are at 1-2 cm distance [Buson spacers] each other [rain + escaping gases]).

ese seem to have one issue which I need to be addressed for my application.
The grids which are produced using the methods on here follow the surface and tend to be equally spaced in two dimensions. What I need is to create a grid which keeps the distance between the path lines equal whether the angle between the lines is 90 of 45 degrees. At the moment the grids act a bit like contours on an OS map but they bunch up in the lower parts of the curves and spread out in higher parts.
Below is a picture of what I produce via grasshopper so far but using a grid formula from elsewhere on the forums along with Rhino to connect up the paths. In this example they seem equally spaced but they differ by anywhere between 0.755mm and 0.785mm which if scaled up would be a problem.
Any Ideas how to help me split the surface up equally in all dimensions, meaning that if I were to sweep the tool path with a circle radius of half the distance between the lines/rails, there would be no gap between the beads/filaments?
I appreciate any help or advice hugely.

st between those two applications. But as soon as every frame is re-calculated I noticed that intersection function is very slow. It is actually so slow, that maximum number of polygons to play with is only 10 or less.
Could you help me to find a faster solution for my script?
calculation of intersection lines;
//////////////////////////////////////////////////////////////////////////////////////////
import ghpythonlib.components as ghcompimport rhinoscriptsyntax as rsdef ctr(crv): pts = ghcomp.Explode(crv)[1] pts = ghcomp.CullDuplicates(pts,0.001)[0] return ghcomp.Average(pts)pts = []lines = []ctr_c1 = ctr(C1)for crv in C2: if ctr(crv) != ctr_c1: int = ghcomp.CurveXCurve(C1, crv)[0] if int: [pts.append(x) for x in int] lines.append(rs.AddLine(int[0],int[1]))
/////////////////////////////////////////////////////////////////////////////////////////////
The overall description of the script:
a)Processing+ghowl is used for moving objects and physics
b)python script (slowest part) calculates intersection lines
c)intersected parts of polygons are rotated in 90 degrees.
I have attached grasshopper and processing files. (processing is not necessary to test the script)
Thank you in advance,
Pereas.

width of the other letter
find the intersecting shape with Solid Intersection
re-orient final shape
This process sometimes breaks when a letter has one or more "holes" in it (eg: B, O, R). When this happens, the Solid Intersection component experiences an error and says "Boolean intersection set is empty". I don't know what that means.
I have tried the quick-fixes of flattening and grafting to no avail.
Could somebody shed some light on this issue?
I have internalized the letters into the attached GH def, but am also attaching the illustrator file that I'm using.…
e any affect, but that's way too slow if 90% of the GH program is initialization and creation of source geometry to then simply alter a bit or array here and there. When I use Python directly to change output values that I plug into former slider inputs, again no new solution is triggered at all so I'd have to recalculate the entire Grasshopper program which is simply not how Grasshopper normally works. How do I actually emulate a human changing a slider value one slider at a time in a way that makes Grasshopper behave normally so that only downstream flow is affected in an efficient way?
An related example would be if you have several separate programs in a Grasshopper page and you wanted to only change one of them without triggering full recalculation of them all.
At this point it's almost like a Windows mouse scripting utility is needed but if I need to do combinatorial combinations of all possible slider values, that seems quite thorny too unless I set up a pre-arranged array of values that could then simply be incremented "manually" followed by a right click to bake and then typing commands into Rhino to save to a file. UGH. That would be quite difficult to pull off since I need to control file names, but it's what I seem to need.
I'm using Python since it avoids thorny Grasshopper schemes and it allows me to access Rhino to save baked objects files.…
ving a copy of the surface in the original position. Second, and more frustrating, not all of the surfaces orient properly. A few lay flat but then rotate 90 degrees horizontally.
Any help or insights would be greatly appreciated!

Refinement component at first, possibly using MeshMachine instead which is slow but actually gives many fewer triangles and adaptive meshing for tight curves too. Neither are easy to adjust on a deadline!
Then you have to sneak up on workable settings, using only a few lines, or Grasshopper will freeze perhaps indefinitely for 200 lines with extreme settings, especially the CS (Cube Size) setting that can blow up into a huge number if your scale is big.
Cocoon gives lots of nearly flat split quad faces so I quadrangulated those for fun:
Or MeshMachine can refine the mesh to make it efficient:
Whereas the Cocoon Refine component will merely return an equally fine mesh with more equilateral triangles but no serious remeshing to rid so many tiny triangles where they are not needed? Actually, it does seem to remesh also:
David said he used some of Daniel's MeshMachine code in there.…

they may not always give you a clear picture of their precise functionality. I thought this may be an issue with many users so I decided to use this opportunity to list all the parameters with my quick take at describing their functionality. Here it goes:
DEFAULT VERTICAL SHIFT -- Number - Shifts panels vertically creating a custom-sized panel with height of the specified dimension at first row of skin.
DEFAULT HORIZONTAL SHIFT -- Number - Shifts panels horizontally creating a custom-sized panel with width of the specified dimension at first column of skin.
DEFAULT SKIN CHAMFERED CORNER--True/False - If "True" wraps panels around surface corners. If '"False" creates a custom-sized panel if necessary to complete the skin surface at the shared edge, defining this way a sharp corner.
RESET BAY AT POINTS-- True/False - When using Panel Bays (Group of Panels) this option restarts the panel bay at a surface corner.
FLOOR HEIGHT-- Number - The Floor To Floor value of the Skin generated. If Panels are shorter than this value, a leftover 'gap' will be seen at top of panels.
MINIMUM PANEL WIDTH -- Number - If the width of a panel (standard or customized) created during the skin generation is less than this value, the panel won't be created and the placement will be skipped.
MINIMUM PANEL HEIGHT -- Number - If the height of a panel (standard or customized) created during the skin generation is less than this value, the panel won't be created and the placement will be skipped.
MINIMUM PANEL AREA-- Number - If the area of a panel (standard or customized) created during the skin generation is less than this value, the panel won't be created and the placement will be skipped.
PANEL PROFILE TOLERANCE-- Number - If a resulting panel shape is within the specified tolerance value to any already created panel, this panel is used instead of creating a new panel shape. The tolerance specifically tracks the distance between each corner of the new panel and the corresponding corners of the existing panels. This parameter is mostly used in "SURFACE PANEL MODE'', where a large number of custom-shaped panels can be generated, to reduce the number of unique panels created.
GENERATE PANEL TYPES ONLY-- True/False - This parameter allows the Skin Generator to discard the creation of scene geometry but still have the grasshopper panel data being generated. The skin panels can be retrieved as grasshopper geometry using SkinDesinger's Display components.
RESET DF BETWEEN SURFACES-- True/False - When "True", the Design Controllers (Design Functions in v.01) resets to its initial values each time it starts a new skin surface. Used for instance to restart a layout pattern at every new surface.
SURFACE PANEL MODE-- True/False - The "SURFACE PANEL MODE" is used to generate panels matching the shape of the surfaces included in the "skinSurfaceList" input.
SURFACE PANEL ORIENTATION -- Orientation Type - When activating the "SURFACE PANEL MODE'', this parameter defines the orientation of the panel generated relative to the normal of the surface that defines its shape. The acceptable values (found in the "Surface-Panel Mode Orientations" dropdown) are:RESETFLIPROTATE 90ROTATE 90 FLIPROTATE 180ROTATE 180 FLIPROTATE 270ROTATE 270 FLIP
