ace and am trying to wrap it to a skin ('map to surface'), but I found the edges at both side could not be connected properly because the 2D surface was divided into diamonds and triangulates.
When I mapped the 2D surface to a skin, the seam was solid. So is there any way that i can make the seam as same as the other part of the skin?
2. To further play with the pattern, i tried to subdivide some portion of the diamonds by using 'Quadsub' to make some of the diamond 50% smaller.
I intent to have some point attractors () to control the random reduce, so that I have have relatively more big openings in some specific areas (depends on how much is the 'Jitter' value? (Shuffling strength))
Please see the attached 3dm and gh files
THANKS in advance for any help!!

from each other (base curve and subtractive curve)
The goal is to get something like subtractive colormixing
-> so the the base curve is something like a white paper
-> if i add a color to it the paper gets darker
it works - but the problem is - if I put the slider of the subtractive color/curve to for example 100 and the base curve is at 50 it get minus values --> whereas the minum in total should be "100 - the numbers of the subtractive curve"
I know it may be a bit confusing - but it really should be just a little trick - so to make it a bit more clear i add screenshots:
As you can see - on top I have a list with 50 as the base curve - from that I subtract the list on the left -> so I get minus number in the list on the right -> and you can see on the rhino window on the right - that the curve is below zero - whereas it should exactly match the upper curve in that situation
to give you a understanding what i want it to look like in reality in that case - I give you another screenshot:
So that is what it should look like - so for example -> If it is 50-94.68 -> value on the right list should hit a minumum at 5.32 (100-94.68)
--> so 100-value in left list should be minumum in right list
I hope i could make it a bit understandable at least - and I really hope that you could help me
Thank you so much in advance
and I hope to hear from you soon
Tom =)

oling consumption in those months i identified as winter/summer. I defined -50 oC and100 oC for such months. But it was a mistake. Just after i defined all the temperatures the same for winter/summer i get the desired temperatures.
2. Equipment/Lighting schedules: I was mixing the occupancy/lighting schedules (when they are ON) with the loads themselves. I suppose i get mislead with one of your previous examples. I think i'm getting right now.
So this is with regard the garbage (attached the file with the fixes if you don't mind to check).
Now the questions:
a. HB_setEPZoneThresholds: I'm defining there Cooling/Heating Det point and Setbacks. I don't see them in the IDF. If i define HeatingCoolingSetpoint schedules in the HB_setEPZoneSchedules these definitions are not written in the IDF?
b. HB_setEPNatVent: Im defining min/max indoor/outdoor temperatures. But i also don't see where in the IDF they are registered.
c. I know you are using DualIdealSystem for the dafault HVAC. There is a way of not calculating cooling for winter months? I'm not defining well this question, but in this example i'm getting cooling loads bigger than heating for winter. Can't be (!!). In the worst case you open windows but don't cool. My faculty building shifts the HVAC from cooling to heating at determined dates in the year. When not needed you don't switch them on. I hope you understand the meaning of the question and find the logic in it. The way i define Ideal Systems allows me to do that, but i can't find how to do that in HB components.
Hope this makes any sense for you.
Thanks for your help.

rolling in the Fabricating Luminance workshop. The INTEGRATE Bursary is sponsored by Studio Integrate and gives students the opportunity to receive a 50% bursary on workshop fees. The bursary is both based on need and merit; if you are interested in attending a workshop but are unable to afford the fees, contact us via our website. Upon receipt of your query, we will ask for a digital portfolio submission (5MB or less) on which we will award the INTEGRATE Bursary.
Fabricating Luminance is an intense 2-day workshop focused on the design and fabrication of a luminous artefact through surface manipulation in Grasshopper, Rhino’s parametric modelling plug-in. The workshop will introduce participants to the concepts of algorithmic design and associative modelling through focused design exercises, investigating possibilities for heterogeneous lighting conditions through the differentiation of component-based systems. Each student will have the opportunity to fabricate and construct their own design with the use of our CNC laser cutter. Objects produced will have the opportunity to be developed further and showcased on the online jewellery and product design shop cyberth.com. The design-based workshop will be supported by a series of presentations related to the workshop content.
The workshop is open to both students and professionals in architecture, product design, industrial design, and any other related fields. To ensure maximum time with tutors, the workshop is limited to 8 students.

t, you can see 6 (+) signs with what you can add (A,B,C,P,Q,R).
Let's say you add A = 90 and B = 50.
Now you can't add the third angle (cause its 180-(50+90) = C output).
What you can add at the moment is P,Q,R.
You choose to add P = 10.
There is no more a possibility to add Q and R.
All component outputs now give us the data.
2. Triangle with P,Q,R
When you zoom the component, you can see 6 (+) signs with what you can add (A,B,C,P,Q,R).
Let's say you add P = 15, Q = 20.
Now if you add R, the component's outputs all the angles and edge lengths.
If R > P+Q then component throws warning. (> or >= ?)
You cannot add A,B or C anymone.
3.Triangle with P,Q and C
When you zoom the component, you can see 6 (+) signs with what you can add (A,B,C,P,Q,R).
Let's say you add P = 15, Q = 20.
Now if you add C (angle), the component's outputs all the angles and edge lengths.
You cannot add A,B or R anymone.
To make it all easier, disable the possibility to internalize the data.
Tolerance issue... Maybe round the angles always to floor , with 0.1 precision ?

Loft is connecting circles on her\his arbitrary way, not counting the wireframe wich is made from Crvs from points.
Like a wireframe in a picture with a last def. from you, such exact Surface I need. Maybe some sweep rail, where a every 2 circles are Rail and a arc (trough 3 point) or segment of interCrv is a section Curves.
At the endeffekt I want to accomplished a worm like a nest, something like a worm city, where people will live in a worms , to create microclima inside ( In direction of B. Fullers dome), it term that one ring(segment) of each worm is a place for 50 or more habitants. Prox. Pro worm 250-500 habitants.
My steps are:
To make a Srf’s from accomplished wireframe.
Then evaluate this surface with Ecotect (that is why I am still using GH 0.6 because of Uto’s plugin for 0.6 and 0.7). And I also have a Rhino 0.4 Sr6
Make a sun reacting facade or pneumocells.
Make a def. to assign a GH def. on multiply Crv’s. For this I need also evaluate a Crv’s length, because of subdivisions number. If I assign the same divisions number to all Crv’s , the longest and the shortest will be divided at same div. Num.! What we don’t see in a nature.
Make a living space inside of worm, with vertical farming, residents, parks etc.... Dividing a worm Srf’s on separated rings (segments) , to count their area. Bigger ring will have a more people and so on...
Make a model :)
I hope that I don’t sound too much pretentious :)…

th (60° max in Paris), but the problem stil arises for the angle theta (for the south but also for the others orientations). For the diffuse radiation, this difference should be 10% as you noticed.
2) I have done some simulations and tried to analyse the weather file used. You can find my results in the Excel File attached. Some simulations take into account the glazing and others just determine the "occultation factor" of the shading device, to which I apply then the solar factor of the window. I found there is a noticeable difference between "_shading_1" and "_Focc_1" for exemple, we should have found similar values ... ? It seems to happen something strange when the rays passe through the glass to reach the analysis points. Facing those results, I still have trouble to draw conclusions. I also determined the diffuse part of radiations for each day from the weather file used, it may help to understand ... If you have any suggestion to explain those results, please let me know.
3) Another point attracts my attention :
The horizontal infrared radiation intensity of the weather file is quite high and constant. I'm wondering if HB take into account this solar radiation's component which represent about 50% of the solar energy ?!
http://bigladdersoftware.com/epx/docs/8-3/auxiliary-programs/energyplus-weather-file-epw-data-dictionary.html#field-horizontal-infrared-radiation-intensity
I continue my research about what is going under the hood (reading documents on Radiance and Daysim calculations) and let you know about the progress of my searches.
Thank you again for your support !

ial command:create: Divide Curve, Voronoi, Area, Circle
If there are multiple instances of a single component, then you can assign them IDs (according to Ángel's suggestion) using square brackets:create: Divide Curve, Circle[1], Circle[2]You can use numbers or words, whatever you want to identify a component.
Parameters are written in parenthesis, in front if they are input parameters, trailing if they are outputs:Voronoi(C) --> (G)AreaThis will conflict somewhat with components which already use parenthesis in their name, but we can simply consider the first or last parenthesis pair to indicate the parameter. In other words, the ambiguity can be resolved because all alternative interpretations are invalid.
K didn't like my usage of an inverse arrow ( <-- ) to assign properties, I didn't like her suggestion of a different inverse arrow ( <== ). The equals symbol seems to be a halfway decent alternative, eventhough K still doesn't like it:Voronoi = Preview:Off
All sorts of properties can be assigned using this notation, including name, position, enabledness etc.
We haven't decided on a good way to assign initial properties quickly. Your first suggestion [Slider=60] may work in conjunction with the create statement, but it is somewhat awkward. I suppose the logical way for this to work is to simply type:slider = 0..10..50using the shorthand notation for creating a new object (by mentioning it out of the blue) and immediately assigning a property to it.
Does this approach violate some of the goals you had in mind originally?

Angeles, which has 12% of the year made comfortable, and Shiraz, Iran, which also has 12% comfortable (assuming default parameters).
Jerusalem also makes sense to me. There is only a maximum possible 9% of the year that is inside the polygon (you'll see this if you set the timeConstant to a very high number). The default strategyPar makes 6% of these hours comfortable and 3% without cool enough temperatures in the previous hours. This seems reasonable to me.
I could be convinced to change the default time constant to 12 hours (instead of 8) as I know that 12 is the default of climate consultant but that seemed really idealized in my opinion. You'll need really high exposed mass and insulation without much internal heat gain to make conditions stable for more than 8 hours in my opinion.
As for the solarHeatCapacity, I get changes when I drop it down to 10 W/m2 or boost it up to 100 W/m2. It's definitely a parameter that operates on an "order of magnitude" scale and little tweaks to it won't change it too much. You can think of this number as representative of a lot of other physical properties: most notably the depth of the space being passively heated and the thermal mass of that space's materials that participate in heat exchange over the time constant. Climate consultant uses a default assumption of 30 W/m2 but, from my calculations, this is likely assuming a space that has a facade to floor area ratio that is greater than 1. If we say that we need to raise the temperature of 10 cm of an exposed concrete floor for passive heating purposes, and we have a facade-to-floor area ratio of 1:
Required solar flux = ((1 facade-to-floor ratio) x (0.1 m3 of concrete) x (2400 kg/m3 concrete density) x (880 J/kg-K concrete specific heat capacity)) / 3600 seconds/hour
This lands you with a required solar flux of 58 W, which is almost twice the 30 W climate consultant default. While me might say that not all 10 cm of concrete participates over the course of a default 8-hour time constant (most of the action is probably within the first 5 cm), we also have to account for things like transmittance of solar though the window, which, for triple pane, is probably only half of the incident solar. So 50 W seemed to be a more reasonable rule of thumb from my perspective, essentially assuming a facade-to-floor ratio of roughly 1 with 5 cm of concrete participating in an 8 hour heat exchange and a little more than half of solar heat getting through a fully glazed window.
Let me know if that makes sense or if you have any suggestions,
-Chris…
