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.

orward polygon modelling combined with a subdivision surface method to smooth the modelled polygon control cage (see this andthis).
The Weaver Bird plug-in has several methods for subdividing and smoothing a mesh including the probably best known method Catmull-Clark as well as laplacian smoothing.
Although Grasshopper is becoming better at handling mesh construction and modelling you might want to consider packages such as 3ds Max, Maya, Modo or Blender for doing the initial cage (they all have most of the standard tools one would except from a polygon modeller). For Rhino there is also the funky fusion between subdivision surfaces and NURBS called T-Splines (gave it a spin a few weeks back, has some pretty decent polygon modelling tools actually).…
s random reduced with the random reduce component.
Then the random reduced surfaces, is extruded in z direction with negative factor, The plane surface is also extruded in z direction with negative factor, then i used Trim solid, and had about 40 boxes cut in the xy plane with different hight.( hight is from the flowing surface)
The i open a new grasshopper file, and take brep container, and get one of the boxes cut in xy plane, but if i use isotrim on the brep faces or subdivede quad from lunchbox, the divide component show orginal extruded surface and not the smaller one i got after using Trim solid, on the extrusion.
is it clear or you need the file, and have anyone a answer
thank you

orders from bottom to top. There are three pre-set heights: 20,000 / 50,000 / 80,000 (or 20, 50, 80 meters, I'm working in mm).
So if the three cantilevering volumes would be numbered 0,1 and 2, then I'm looking for a way to let Grasshopper generate the following:
A = 20m-position
B = 50m-position
C = 80m-position
(A,B,C):
0,1,2
0,2,1
1,0,2
1,2,0
2,0,1
2,1,0
Attached is wat I have so far, I have only managed to make simple translations per geometry.

summer because of the relative humidity of outdoor air will be over 80%.
I want to set the schedule like this
1) cooling setpoint to be 27C degree and max humidity to be 50%.
2) when the outdoor air temperature is lower than 27C, open the windows and ventilation naturally.
3) Air conditioning and dehumidification are needed only when the occupancies are at home (almost at night) and Natural ventilation is not to be.
4) Accept the indoor air relative humidity to be almost 100% when dry bulb temperature is lower than 27C.
Now, I set the air conditioning schedule as cooling setpoint schedule, but there are no components to set a dehumidification setpoint schedule.
The dehumidifier keeps working all day whichever the windows are opening or not.
How can I stop the dehumidifier during the windows open?
thank you.…
llowing for higher skyline and construction areas along public transportation corridors. Up until now, neighborhoods once characterized by two-story houses, gardens and ground- floor open shopfront programs, have been completely transformed by the introduction of fortressed monolithic residential and office towers, which lack any sort of urban street life.
The new master-plan, however, now requires buildings to have an open street façade to accommodate multiple programs. Led by tutors from UNStudio (www.unstudio.com), the AA Visiting School São Paulo will address the changes being prescribed by the new masterplan through the redefinition of the tower typology in the extending of the ground of street culture, green landscapes and ecological mediation along the vertical axis of these buildings. For this, the workshop will teach advanced digital design and fabrication techniques to explore a series of novel differentiating structural and environmental organizations in the redefinition of the São Paulo skyscraper.

angel but when it comes to material behavior, stresses, surface tension i think that "our" tools are still no complex and powerful enough - and like i said i didn't really see the benefit in the work of my friend form the digital experiment.
so i think the question is is there a benefit from your digital experiment or do you rather stick to the physical experiment.
