when i type the equations for z,y,z it says a syntax error so i obviously do not understand how to construct an expression. (screen capture attached)
Any help/explanation of using this function would be greatly appreciated
thanks so much

rking at CITA http://petrasvestartas.com/Inflated-Restraint . Then I wrote my graph library in C# that has graph algorithms such as shortest paths(dijktra's, bfs, dfs), minimum spanning trees and etc. for Fox. It is not so difficult to read this book and implement graph methods in C# from pseudo-code: https://www.amazon.co.uk/Introduction-Algorithms-Thomas-H-Cormen-eb... The method that you pointing at is using multiple dijkstras for striping.
The thing with tiling use simple loop no recursion, at least this is more readable for me. Isosurface is also part of the Fox add-on. But as you know iso surface is just display thing, field value is what you checking at. Also colliding thing is faster if you do not check edge edge collision.
Another thing is you do those "aggregations" in 3D and you do not evaluate material properties of the real object, be it plywood, plexiglass or 3D print powder. It seems , if you make a physical prototype it will be strong as 3D, but it bends as tree branches because it holds only to one element. There are different way how to overcome that and make structure stable/lock it and branch back. Also take into account torsion forces of the connection.…

hen you determine their position and number by the "precision_" input. Their number is equal to "precision_ - 1".They are essentially mesh edges, not curves. To hide them, in Rhino application menu choose: Tools -> Options -> View -> Display Modes -> choose your current display mode, and uncheck the "Show mesh wires":
b) How do you change the x- and y-scale of the chart? For instance displaying every 10 degrees of azimuth?
Can you be a bit more precise?You would like to change the labeling of the azimuth directions from 30 degrees step to 10 degrees step? If this is so, you can not do that.
c) My input surface is a hyperbolic paraboloid, facing south symmetrically. How does the component calculate its tilt and azimuth?
All Ladybug Photovoltaics components calculate the amount of AC energy generated by a planar (flat) surface. Tilt and azimuth angles are calculated based on surface normal at 0.5, 0.5 surface parameters. So you can not use the hyperbolic paraboloid as the _PVsurface (or _PV_SWHsurface) input, as it will yield incorrect results. You need to planarize that hyperbolic paraboloid surface first.I attached below an example with default grasshopper components, but the size of the panels is not equal. If you want them to be equal use some paneling Grasshopper plugin like Lunchbox or Paneling tools.…
onents (radiation, sunlight-hours and view analysis) which let you study the effect of the orientation of your building and the analysis result. When you come to a question similar to "what is the orientation that the building receives the most/least amount of radiation?" is probably the right time to use this component.
HOW?
I'll try to explain the steps using a simple example. Here is my design geometries. The building in the center is the building to be designed and the rest of the buildings are context. I want to see the effect of orientation on the amount of the radiation on the test building surfaces from the start of Oct. to the end of Feb. for Chicago.
First I need to set up the normal radiation analysis and run it for the building as it is right now. [I'm not going to explain how you can set up this since you can find it in the sample file (Download the sample file from here)]
Now I need to set up the parameters for orientation study using orientationStudyPar component. You can find it under the Extra tab:
At minimum I need to input the divisionAngle, and the totalAngle and set runTheStudy to True. In this case I put 45 for divisionAngle and 180 for the totalAngle which means I want the study to be run for angles 0, 45, 90, 135 and 180.
[Note1: The divisionAngle should be divisible by totalAngle.]
[Note 2: If you don't provide any point for the basePoint, the component will use the center of the geometry as the center of the rotation.]
[Note 3: You can also rotate the context with the geometry! Normally you don't have the chance to change the context to make your design work but if you got lucky the rotateContext input is for you! Set it to True. The default is set to False.]
You're all set for the orientation study, just connect the orientationStudyPar output to OrientationStudyP input in the component and wait for the result!
The component will run the study for all the orientations and preview the latest geometry. To see the result just grab a quick graph and connect it to totalRadiation. As you can see in the graph 135 is the orientation that I receive the maximum radiation. Dang!
If you want to see all the result geometries set bakeIt to True, and the result will be baked under LadyBug> RadaitionStudy>[projectname]> . The layer name starts with a number which is the totalRadiation.

her people) a tremendous amount of time creating them by hand. Dog Treat was far from perfect, however it was good enough to use almost daily.
Three years is a long time. Since 2016 my Gh knowledge has expanded and I’ve seen how dodgy some of the scripting is. With this in mind I started work on a new build. Many things have been tweaked and some things have been rebuilt from the ground up.
Everything has been designed to be leaner and be a general solution to the problem of creating dog bone corners on geometry for quick, efficient and safe CNC fabrication.
Some of these things are:
Adding prompts about user geometry to make them aware about open curves, varying curve heights and if their geometry had been altered (mostly removing unnecessary points on curves).
Smooth Transfers. If you’re in a rush and need to speed through cutting, smooth transfers mean that a lead in geometry is now created alongside the actual dog bone arc. This means the router bit doesn’t have to come to a minute stop at every corner. This is turned on by default.
Acute Angle Condition If the angle between the two curves adjacent to a dog bone point is acute, previously the dog bone corner was useless. This was because the distance between the end points of the dog bone arc were less than the diameter of the router bit. There are many ways this condition could be addressed. I chose to circumscribe a larger arc based on the original angle between the adjacent curves. While it removes more material from the corner, it minimises tool wear and any potential for material to burn.
Single Curve A single curve can now be input into Dog Treat. It will be output with both internal and external treatments.
I’ll continue to update Dog Treat as the need arises, it’s become somewhat of a hobby now. Maybe one day it will become part of a Plug-in… once I learn to code it though!
Happy Treating!
Hi Everyone,
Here's a tool I've been working on for the past 4 months or so in my free time. It's a dog bone corner generator, however it's a little different to some of the existing ones. It's designed to be used for large amounts of geometry and as such, it avoids using any curve boolean operations that are computationally taxing. You don't have to split your curves up into internal and external lots either, it works it all out so you can be lazy. I've also incorporated Lunch Box's Object Bake Component for a one click operation that bakes geometry back out to Internal and External profile layers.
Let me know how it goes, will update where necessary.
Best,
Darcy

thought that architect's love for drawing comes from the necessity of translate abstract ideas into built 3D reality, and the technology behind that 2D representation has not evolve so much until some decades ago. Our teachers come from that times: times when computers try to find their place in the reality representation world. If you try to imagine that people that have always drawn with pencils adapting to this new tools...some become fan of new methods, other just keep the old fashion workflow (like Andrew said in the article, Schumacher VS Graves)
We've bear (at least Andrew and me :P) in 80's with first video games, computers (I still remember my old x286 with 1Mb RAM and 20Mb of HD and that MS-DOS interface)...New technology was natural for us...But there is a big difference between traditional drawing and new computer aided tools: the learning curve. To draw you only need to take a pen and put over a paper (that interface is understood by children easily) , but traditional computational tools (new touch interfaces are out of this group) are based in a complex logic and environment that is not easy to understand for some people.
In the workshops I'm teaching in, I try to put all that tools (new and old one) in my students hands and motivate them to mix and use them together (Andrew knows a little bit about that :P). Why not to make a lines sketch with GH and then print it and render with some markers?; the last step could be scan the result and enhance it in Photoshop adding textures, vegetation, some background...There are no rules, only a bunch of tools to explore and use to develop your ideas, evolve and finally represent them.
I bet to the touch interfaces (with some augmented reality sauce) like that one that will be able to blend both worlds, analog and digital, offering that fluidity and natural interaction that Grave miss in digital tools. And our generation attached to this "not natural" interfaces will need to change its mind and adapt to that new and amazing interface that our children will love.

e volume. The yellow line above.
This volume, green on the above image
So with this there was an intersection with the Brep volume of the chair and the lattice.
After that I used cocoon. Here the parameters I used for the Brep and curve. So The Brep was offsetted.
The model is 80 unit height and cell size is 0.2 so roughly there are 400 divisions in Z. If cubic it will give 6.4 millions of cells. To my point of view it is important to choose well the cell size in order to have not hundred of million of cells. Here 6 millions was usable. The general thing with Cocoon is alwas to test it on small objects first.
A close view of mesh. Edge length is 0.1 unit. There are 6 millions of triangles.
