(Boundary Representation]. Thus a Brep is 2 things: the underlying "guide" surface and "regions" that do the massacre.
2. As delivered and if you chose the equivalent boolean some Delaunay faces are removed from the mesh IF their center (the projection in an automated made "min" plane) is contained (is inside) to a giiven hole. Now ... the anchors ARE not the white points ... they are their projections on the terrain (the red ones). Thus proper springs "pull" the white points towards the red ones.
3. Max span is a term used in that ugly part of life (the real-life) and indeed refers to some distance between mount points. For instance the Golden Gate has a max span of 1280 m. Span means money and big span ... er ... means lot's of money (even on trusses, considerably less so in tensile membranes).
5. Coding is like riding properly a proper Ducati (avoid the 999 at any cost): easy provided that you can ride it. Lethal in any other situation. But the good (or bad) news are that girls don't ride that type of bikes.
6. This makes me entirely off-topic > Oops > anything that I do/think points directly or indirectly (in most of the threads in this Forum) towards real-life AEC thingies. I never (ever) think within an Academic/Theoretical framework. BTW: Avoid social networks > or say hello to Skynet (or lobotomy).
7. You are very kind.…
to Daniel Pikers' Tutorial mesh relaxation tutorials we are already pretty far.
The Idea of our design is a hanging structure suspendend in a gap between buildings, where you can find places to rest, read or even to sleep. You can find privacy in the cocoons, that are connecting the planes with each other.
As structure we have a net in mind, that is tighter in the area of the cocoons and more transparent in the common areas, but we really don't know whats the right way to get to this point.
In the end of the project we need a printable geometry. We start our boxy design in Sketchup, and remesh it in Rhino. After that we feed it in our kangaroo definition.
1. A nurbs surface could give us more freedom (for postprocessing in tsplines) to form meshes with shorter and longer edges, representing our net. But I see now easy way to get a surface out of the relaxed kangaroo mesh.
2. Working with the kangaroo mesh could also work fine, if we'd find a way to control the edge length of the mesh (for example 20 cm in the common area and 5 in the privates) with an attractor point. Remeshing with Daniel's Plankton Plugin sadly doesn't work, I always get the "runaway faces circulator"-error.
3. It woud be great to convert the mesh to a hexagonal mesh, but I don't know any possibility to remesh an existing one...
You see, we're full of questions, but I really hope to get some help here :)

hat, in accordance with this stable release, I have posted an updated version of this outdoor microclimate map example to the same link:
http://hydrashare.github.io/hydra/viewer?owner=chriswmackey&fork=hydra_2&id=Outdoor_Microclimate_Map
1. You will see that, in the new file, I now have a single component that is able to turn a zone into a "ground zone" (similar to a plenum). To clarify, both the plenum and ground zone components set all of the loads of the zone to 0 (no internal heat gain). So this means that any of the characteristics of the default office program will be negated. From your comments, Grasshope, it seems that you understand that the reason why I have a ground zone defined in this model is to account for the variation in ground surface temperatures that can occur with different objects casting shade onto the ground. Therefore, the key property that defines this zone is the construction of the top surfaces, which is now changed based on a number that you input into the Ground Zone component.
2. You are correct in understanding the need for both "set zone construction" components in the old file. Because of the zone's position below the Rhino model origin, the walls and floor are defined as underground surfaces and so I need the extra "Set EP Ground Construction" component. Admittedly, the constructions on the underground surfaces should have a minimal effect on the modeling of the surface temperature above the zone (the roof construction is most important) but it made sense to me that results would be more accurate by setting all of the constructions of the zone to the ground material. The current Ground Zone component ensures that all surfaces of the zone are assigned the ground material construction. It also ensures that all walls and floor surfaces have a ground boundary condition regardless of where they sit in relation to the rhino model origin.
3. The distFromFlrOrSrf input can take either a number representing the distance from the floor of zones at which you would like to build a microclimate map or any surface on which you would like to see temperature variation. So the input is flexible and allow you to both build micro-climate maps quickly or take a longer time building them with more customization. For a visual of what you can do by inputting surfaces into this component, see this thermal animation of a section through a building that I designed for my thesis:
https://www.youtube.com/watch?v=WJz1Eojph8E&list=PLruLh1AdY-Sj3ehUTSfKa1IHPSiuJU52A&index=3
For an example of a file using a numerical input for the microclimate map, see here:
http://hydrashare.github.io/hydra/viewer?owner=chriswmackey&fork=hydra_2&id=Indoor_Microclimate_Map
4. The component has since been renamed (sometime in early July) to be called "Honeybee_Microclimate Map Analysis". Originally, I developed the component to help me understand thermal diversity within zones but realized after building it out that the same method could be used to give deeper understandings of the outdoor environment. So, at present, it can do both indoor and outdoor microclimate maps. The only shortcoming at present is that the outdoor microclimate map uses EnergyPlus's oversimplified means of accounting for outdoor wind (a simple wind profile that does nto account for obstructions). This shortcoming will be addressed once the first stable release of butterfly is out or I manage to work in components into LB that use the botlzman lattice particle collision method to approximate outdoor wind speeds. Other than this shortcoming, you can trust that all results you are getting from these components are to a high degree of accuracy (meaning that all air temperature and MRT values are accurate).
5. Thanks for pointing this out. This is a mistake in my labeling of the file names and I will fix this before the end of today. When you use the workflow with the PMV recipe, these values are actual PMV/PPD values. When you use the Adaptive comfort recipe, these values are "degrees from neutral temperature" and "Comfortable Or Not" values. When you use the workflow with the UTCI recipe, these values are also "degrees from neutral temperature" and "Comfortable Or Not" values but they are different for UTCI than they are for the adaptive model. Specifically, the neutral temperature and comfort zone for UTCI is defined to be the same as it is in this publication:
https://www.ipma.pt/en/enciclopedia/amb.atmosfera/index.bioclima/index.html?page=utci.xml
Hope this helps and let me know if you have any more questions,

, Engineer and Researcher from France with broad programming experience. He is the author of the City in 3D Rhinoceros plugin for creation of buildings according to geojson file and with real elevation. Guillaume already created a new component: "Address to Location". It enables getting latitude and longitude values for the given address:
2) Support of Bathymetry data: automatic creation of underwater (sea/river/lake floor) terrain. This feature is now available through new source_ input of the "Terrain generator" component. Here is an example of terrain of the Loihi underwater volcano, of the coast of Hawaii:
3) A new terrain source has been added: ALOS World 3D 30m. ALOS is a Japanese global terrain data. Gismo "Terrain Generator" component has been using SRTM 30m terrain data, which hasn't been global and was limited to -56 to +60 latitude range. With this addition, it is possible to switch between SRTM and ALOS World 3D 30m models with the use of source_ input.
4) 9 new components have been added:
"Address To Location" - finds latitude and longitude coordinates for the given address.
"XY To Location" - finds latitude and longitude coordinates for the given Rhino XY coordinates. "Location To XY" - vice versa from the previous component: finds Rhino XY coordinates for the given latitude longitude coordinates. "Z To Elevation" - finds elevation for particular Rhino point. "Rhino text to number" - convert numeric text from Rhino to grasshopper number. "Rhino unit to meters" - convert Rhino units to meters. "Deconstruct location" - deconstructs .epw location. "New Component Example" - this component explains how to make a new Gismo component, in case you are interested to make one. We welcome new developers, even if you contribute a single component to Gismo! "Support Gismo" - gives some suggestions on how to make Gismo better, how to improve it and support it.
5) Ladybug "Terrain Generator" component now supports all units, not only Meters. So any Gismo example file which uses this component, can now use Rhino units other than Meters as well. Thank you Antonello Di Nunzio for making this happen!!
Basically just forget about this yellow panel:
This panel is not valid anymore, so just use any unit you want.
6) A number of bugs have been fixed, reported in topics for the last couple of weeks. We would like to thank members in the community who invested their time in testing, finding these bugs and reporting them: Rafat Ahmed, Peter Zatko, Mathieu Venot, Abraham Yezioro, Rafael Alonso. Thank you guys!!! Apologies if we forgot to mention someone.

option, after downloading check if .ghuser files are blocked (right click -> "Properties" and select "Unblock"). Then paste them in File->Special Folders->User Object Folder. You can download the example files from here. They act in similar way, Ladybug Photovoltaics components do: we pick a surface, and get an answer to a question: "How much thermal energy, for a certain number of persons can my roof, building facade... generate if I would populate them with Solar Water Heating collectors"? This information can then be used to cover domestic hot water, space heating or space cooling loads:
Components enable setting specific details of the system, or using simplified ones. They cover analysis of domestic hot water load, final performance of the SWH system, its embodied energy, energy value, consumption, emissions... And finding optimal system and storage size. By Dr. Chengchu Yan and Djordje Spasic, with invaluable support of Dr. Willian Beckman, Dr. Jason M. Keith, Jeff Maguire, Nicolas DiOrio, Niraj Palsule, Sargon George Ishaya and Craig Christensen.

hit Commit.
I'm wondering how hard it would be to have an edit box which shows the
number the user could click inside of then type in a new number, then
hit enter. :)
2) How would I go about using one line from a table and assign each
field to a variable? Then, move a slider or something and use the values
from the next row?
background: I'm recreating elbows, Tees, and other fittings using
paramatric scripts, then baking and exporting them. Here's one source
table, http://www.wardfittings.com/Assets/PDFs/0902CatalogColorOld.pdf
page 5, the uniform elbows.
Current Setup: the attached ghx file. Create a point at 0,5,0 in a blank
document with units set to inches, then assign that point to the top
left 'Center Pnt' in the ghx file.
Current workflow:
a) Modify variables A, B, H, and Nominal Dia to match one line from the
table in the linked PDF file, page 5, table of regular elbows.
b) Select the 'Nodes' and 'Surfaces' with a drag box
c) Click 'Bake'
d) Switch to Rhino window, do the 'sellast' command.
e) Drag baked objects along Y axis so the center point is at 0,0,0
f) Run 'Join'
g) Run 'Cap'
h) set the 'node' points to a layer called 'nodes'
i) set the surface to a layer called 'fit-3d'.
j) select the surfaces and nodes
k) export selected
This elbow that I'm doing only has 12 rows, so doing it the above method
doesn't take THAT long. I'm also going to be doing a couple with larger
tables like the Tee on page 8, and in other spec files. As you can
imagine, entering in EACH value into a slider is a bit tedious.
I'd love to take the pdf table, run it through an OCR program to convert
to excel, modify the headers so the ghx script knows what they are, then
paste it into grasshopper, or save it and have grasshopper read it, and
I be able to move a slider or something to to select one line at a time.
Has anyone done something similar? ie: assigned one row in a table to a
predefined set of variables, each variable coming from one field in the row?
Thanks for taking the time to read this message. :)
I'm making a rhino script to do steps d-k, so that part will be much faster.

the other pluggins again, I doubt that problems arise and if I already have them Which are due to the autodesk pluggins that I can install on another computer or mount a virtual machine, but I doubt it, I simply had to install Grasshopper first and then the rest.)
Problem:
Good day, afternoon or night, please help I can not install the Grasshopper plugin 0.9.76.0 in Rhinoceros 5SR13, I do not know if it is because I uninstalled the version of 32 Bit of Rhinoceros and I only have installed the 64 Bit version, I have installed on Rhinoceros 64 Bit:
Autodesk Realtime Renderer 2014 x64 Autodesk Shape Modeling 2014 x64 Autodesk T-Splines 2015 x64 V-Ray 2.00.23938 for Rhinoceros 5 x64 V-Ray Express 2 for Rhinoceros 5
I would infinitely appreciate the resolution to this problem, for the moment I can not think of anything other than to uninstall everything and leave only installed the program Rhinoceros 5SR13 with Grasshopper 0.9.76.0 and nothing more.
I already tried to download another new file from Grasshopper 0.9.76.0, which ruled out that this installer is wrong, what I could do is look for another version of Rhinoceros but I have the newest one or one of the newest versions: Rhino_5.13.60913.21340_x86_x64_Multi. Exe
I understand that the Grasshoper installer is showing me a message where it says there is a Win32 exception where the system can not find the source file, what I do not know is if this exception has to do with the Windows C /: Folder: Windows, subfolder: System32 or I do not know if it refers to that as I do not have the 32 bit version of Rhinoceros maybe the installer gets confused and generates the installation error exception.
Another thing to which the exception is associated is the start process file: Start.nfo or start information.
There is also a programming argument for file upload errors of boolean operations (geometry operators) associated with the platform operating system, a process called child process.
Also appears another note that says the installed package of a plugin called inspector and I do not know what else I can not explain.
I do not know what to do, I just happen to uninstall and install everything and I do not think the Rhinoceros installer has any errors, I have Windows 10 edition of Red Stone 1 of 64 Bit.
Thanks and if anyone had this problem and solved it please tell me how to fix it or if someone knows about programming you can tell me why all those errors or exceptions are.
Greetings, have a nice day, afternoon or night wherever you step or stand or wherever you are sitting or lying down.…
ies a step further towards informative models, how to extract data through a parametric process and design analysis which leads to performance based schema.The workshop will cover some advanced modeling techniques in grasshopper along with some useful grasshopper plugins "GECO,WEAVERBIRD,KANGAROO and more". An introductory to ecotect analysis will also be inculded.The workshop is dedicated to intermediate Grasshopper users " knowledge of GRASSHOPPER equivalent to which gained in Parametricisim WS or higher is preferred".Knowledge of ECOTECT is a plus but not necessary".
