ed when membrane cones are invited to the party (then mesh (via Starling is the best way) the brep and send data to Kangaroo : the easiest thing to do). But patch doesn't trim the inner Loops and ... well initially I thought to find this in SDK and do the job:
Well... I confess that I can't get the gist of the Brep.Trim (as explained in SDK).
Thus go to plan B: having already the closed breps (the "cones") as cutters ... attempt a Boolean difference
but this does that (this looks to me a bit paranoid, but some reason must exist):
What I want is this:
the code that mess things is (open the script inside definition attached):
BTW: where in SDK is that DeBrep thing?
BTW: Delaunay GH syntax is still cryptic to me (but this is not an issue anymore)
I would greatly appreciate any help on that final step (to greatness).
The full working definition soon (v5: with 90% of components replaced by C# stuff).

bout angle since the exact same wires can suddenly start working fine later! Just adding new items to Rhino and then using undo to get back to your failing geometry will fix it sometimes?! Flipping the pair of curves' directions, either one or both, fixes it. It's just black box broken. It happens for really boring angles near 90 degrees.
Rotating the entire pair in space has no effect.
Rescaling the lines from their joint point has no effect.
Simply cutting and pasting the lines out of Rhino back in *sometimes* fixes it, so it's angle and something else that makes certain lines "toxic."
Duplicating the pair of failed lines via alt-dragging the Rhino gumball fails to fix it.
Running the "line-like curves" through a Line component to give "lines" doesn't fix it.
Re-creating the lines by extracting endpoints fails to fix it.
Each line, if separated from each other works fine.
Grafting makes each line into its own little cylinder minus a hub.
The error is the boilerplate "Object reference not set to an instance of an object."
Once the pair spontaneously starts working I cannot reproduce the error with that pair again, though sometimes Rhino undo will get me back to failing.
CAN ANYBODY REPRODUCE THIS WITH MY FILE? If so I can submit a bug report.

Source code is here but it's for compiling, not something I can just test in a C# component out of the box:

s is like flattening your data PARTIALLY - chopping an index off the end of the branch paths without obliterating the tree entirely. When working with one "set" of input data, a flatten works to get these lists to match up - but when working with multiple sets, we need to be careful to preserve the original branch indices that keep all four of your original regions separate. As a rule, whenever you're feeding two data trees into any component, they should have the same number of branches. (or one should have branches and the other should be a flat list, in other cases).
The rule of thumb I tend to teach is this:
In 90% of cases...
For lists, all your inputs should either have 1 item or N items. That is to say, if you're feeding 4 items into one input and 9 items into another, something is probably wrong.
For trees, all your inputs should have either 1 branch or M branches. That is to say, if you're feeding a tree w/ branches {0;0} to {0;3} into one input, and a tree w branches {0;0;0} to {0;3;8} into the other input, something is probably wrong.
Grasshopper essentially matches up branches first, then lists second. By "matching" I mean it processes them together. Simple example of the Line component - it will match the first branch of points in the A input to the first branch of points in the B input, creating lines between those points, then match the second branches, the third branches, etc. THEN, it applies the same logic to the level of the list (with a pair of matched branches {0;2}, match all the items in those branches to each other - first item in one branch to the first item in the other branch, etc.)
This is a tricky concept but it seems like you're already well on your way to understanding it from your definition - "PShift" is a critical tool in your path management arsenal. I hope this (overly long) response helps clear things up for you!

he TOF and TSRF indices. They show, how "distant" is your _PV_SWHsurface from the optimal _PV_SWHsurface surface in terms of tilt and azimuth angles.However, in your case we are not interested in TOF and TSRF indices. We would just like to know what are the _PV_SWHsurface optimal tilt and azimuth angles, regardless of the supplied _PV_SWHsurface.
So the circular surface supplied to the "TOF" component's _PV_SWHsurface input is irrelevant. It can be of any area, and any tilt/azimuth angle.The PV_SWHsurfacesArea output of the "PV SWH system size" component depends on a couple of factors:moduleActiveAreaPercent_ (leave it at 90%).
moduleEfficiency_,
systemSize_.Calculation of systemSize_ depends on your electricity demand, cost of the PV system, type of the object, country, local regulations etc. This is something that an engineer needs to determine.For example, in USA for a residential house in the Sunbelt, depending on finances, a household would try to cover 100% of its annual electricity needs with their PV system. Which means that the systemSize_ you chose needs to cover the annual electricity consumption. You can perform EnergyPlus simulation or use any other way to get the annual electricity consumption.
Ladybug "Photovoltaics Performance" component can calculate the optimal systemSize_ by given the annual electricity consumption.However the component is made to address fixed tilt and azimuth PV systems only.An approximate way to overcome this is to calculate the optimal systemSize_ for fixed tilt and azimuth PV system, and then multiply it with the "difference in %s" panel at the very right of the fixed_vs_tracker_PV2.gh file. Again, this is not what Ladybug "Photovoltaics Performance" component is made to do, but it will probably get you in a ball park.
Inputted 32 degrees for north_ direction is actually 328 degrees.This is due to Ladybug Photovoltaics being based on NREL model which uses clockwise angles convention. This convention is also most commonly used in solar radiation analysis.

1. COURSE MODULE (20-23 April 2014) - optional
+ type: 3 days intensive course regarding basic knowledge in parametric design (LEVEL 1)
+ software: Rhinoceros & Grasshopper
+ plugins: Kangaroo, Weaver Bird, Lunch box, Ghowl, Geco
+ achievements:
- acquainting to the components & the concept of Generative Design
- understanding the strategies in Algorithmic Design
- how to easily insert simple mathematical equation into the project to gain more control

2. WORKSHOP (23-27 April 2014)
A 5 day Design-Based Research Workshop exploring new techniques in Digital Architecture/Fabrication, with a specific focus on the use of generative systems and parametric modeling as tools for creative expression.
Our ultimate goal is to increasing the efficiency of utilizing digital tools in parallel with geometric performance of the primitive design agent.
+ + CONCEPT
Fashion and Architecture are both based on basic life necessities – clothing and shelter.
However, they are also forms of self-expression – for both creators and consumers.
Both fashion and architecture affect our emotional being in many ways.
The agenda of this workshop is to investigate on the overlap between these two areas of design, art & fashion.
Fashion and architecture express ideas of personal, social and cultural identity, reflecting the concerns of the user and the ambition of the age. Their relationship is a symbiotic one and throughout history, clothing and buildings have echoed each other in form and appearance. This only seems natural as they not only share the primary function of providing shelter and protection for the body, but also because they both create space and volume out of flat, two-dimensional materials.
While they have much in common, they are also intrinsically different – address the human scale, but the proportions, sizes and shapes differ enormously.
+ + + OBJECTIVES
So far, Architects have been using techniques such as folding, bending etc. to create space, structural roofs or different other structural shapes.
The agenda of this workshop goes further with the investigation of algorithmic thinking through generative tools Integrated in design.
The challenge is creating a bridge that connects these two areas of design, architecture and fashion that perform at two opposite scales.
+ + + + TECHNICAL BRIEF
In the early stages physical models and low-tech strategies will be used, allowing the participants to gain a greater understanding of materials, fabrication and assembly methods as well as simple, yet pragmatic structural solutions.
Later in the workshop these strategies will be digitalized and elaborated using software visualizing tools such as Rhinoceros and the algorithmic plug-in Grasshopper.…
, 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.

(1) I have been exporting small sections of a larger model into Maya from Rhino as FBX. In Maya I rotate and scale the models (-90 in X, Scale XYZ 0.001). The Named Views are being saved, but do not have a successful import into the Maya model. They do not appear as in Rhino, and the problem is not solved by scaling or rotating the cameras.
(2) If I try going the other direction, the cameras exported from Maya as FBX are also not aligning with the model in Rhino as they are in Maya.. I will do my best to post some images of the problem and hope you can help.
error !!
This is what the named views look like
here I am trying to the other way with a good view from Maya
strange placement..
This is the best result I can achieve, after I scale the camera by 1000
Any Advice???
Thanks, Robert.

When you run the simualtion you will notice on the batch terminal that Daysim is also being called, so you may want to consider how Daysim uses Radiance files & data.
Regarding your current problem, I think you stumbled onto something weird and interesting.
Interior and exterior readings appear to differ by 40 in the best case scenarios. Even setting the transmittance to 1 yields similar results. I tried changing from cummulative sky to climate sky and got similar values. Changing the test points did nothing either.
I think, (yet I'm too lazy to prove this) that the difference in values stems from diffuse radiation over the sky dome.
If you delete everything except the glass you'll notice that interior values are like 80-90% of the exterior values (this seems like the expected behaviour with a transmittance of 1). So, if we consider that a vertical window, part of an opaque box, is receiving radiation from 25% of a sphere, as you start to inset the interior test points the radiation they receive will be a fraction of the 25%.
Let me try to explain this better...The exterior surface receives radiation from a section of a sphere calculated by 180degrees on the xy plane (let’s call this angle theta) and by 90degrees (let’s call this angle phi) in azimuthal elevation. If you integrate this over spherical coordinates (theta from 0 to pi; phi from 0 to pi/2) you will find that it comes to a quarter of a sphere. By comparison, the interior surface will not integrate theta from 0 to 180degrees,nor phi from 0 to 90degrees, instead it will be the subtended angle from the exterior surface as a function of their separation; the farther in you go the smaller the view of the outside.
If my hypothesis is correct there shouldn't be that much difference since the separation is only 10cms...the subtended angle would be like 170 instead of 180 for theta and 85 instead of 90 for phi...overall if you integrate both spherical areas there should only by a difference of 10%.
In conclusion, I believe the unexpected behaviour stems from the previous subtended angle thing. If direct radiation was the only factor the difference would be the aforementioned 10%, which suggests that an additional source of energy is also affected by this. Perhaps indirect and diffuse radiation from other areas of the sky dome.
I’m definitely intrigued on why this is happening. Please post if you figure it out.
Regards,
Mauricio
