r "virtual partitions" as follows:
What I mean "air walls" here, is derived from the description of the E+ documentation with the header of "Air wall, Open air connection between zones". (Page 17, http://apps1.eere.energy.gov/buildings/energyplus/pdfs/tips_and_tricks_using_energyplus.pdf)
As I understand, the term "air wall" used in E+ here refers to a description of something like "boundary condition" between adjacent interzone heat transfer surfaces, but not a kind of "construction or material" (like air space resistance or air gaps within a wall/double glazing window).
The main purpose of introducing the "air wall", is to simulate or approximate the airflow/convection/natural ventilation effect between multiple thermal zones which are connected by a large opening.
In my previous tests, using HBzones and GB, I managed to create the gbXML file which can be successfully imported to DB (without assigning any constructions within HB). And the adjacency condition can be recognized automatically by DB, even when I did not use the "Solve adjacencies" component in HB - shared surfaces between multiple thermal zones are recognized automatically by BD as "internal - partition"(which are standard partitions, but not virtual partitions).
In order to create/approximate "virtual partition", I need to manually draw a "hole" in the standard partition surface (fig.1&2). Again, the reason why we want to use "virtual partitions"(or "air wall") is that it allows airflow between multiple thermal zones which are connected by large openings and we could get different temperature of the each subdivided thermal zone which compose a large thermal zone.
My question is, if there is a possible way to simulate/approximate this kind of "virtual partitions"(or "air wall") in HBzones or in GB? If so, I would like to test if DB recognizes it or not. Actually, we expect that there is no need to involve any manual operations (like drawing a "hole" in the standard partition surface) in DB, due to an automatic optimization loop.
Thank you!
Best,

he 4 lines needed for each polygon into one list, creating a data tree with as many branches as the sides of the polygon. You have created three lists of lines, so the middle radial ones need to be repeated and shifted so that you have all four sides for each polygon you want to make.

p et/ou Rhino puis je déplie l'ensemble pour un usinage de chaque pièce en cnc ou Laserco2.
Quand il n'y a pas trop de pièces ça va, mais quand j'arrive à 25 ou 30 pièces c'est dur de retrouver la place de chacune.
J'arrive à sérialiser mes pièces avant dépliage avec le plug rhino "paneling tool", puis à les taguer.
Grasshopper peut il faire qq chose pour moi?

the basic line or vector of my object in Grasshopper, and not the actual shape. IE: A circle only comes up as a single half-arc, while a cylinder only show two circles with a single line between them. I've played around with view and preview settings but nothing seems to change it. I can only see the actual object in rhino when I've Baked it.
Is there anyway to fix this so that my manipulations in Grasshopper are previewing in Rhino in realtime? I'll try to get a picture posted to show what I mean.
Thanks,

where I could choose the layer and options up front one time, and then expedite the baking process.
The scenario Im in is that I have finished a good script for dividing a surface from a set of referenced XY planes. However, I have about 50-60 surfaces, with 6 bakes each for different component outputs, meaning 200-250 bakes. The computer likely can't do them all at the same time, so that's out of the question. I plan to reference them in one by one (which is fine, i've budgeted the time), but some sort of boolean-bake tool would sure make my life easier.
Thanks!

didn't look at it that closely), other than to say tree data structure is helping you and hurting you.
What I did to fix the file was work backwards. Looking at only the left panel you are trying to create 11 total planar surfaces from edge curves (8 curves per surface). That means you should be generating 11 of each type of curve so that you will have 88 total curves when you attempt to join them.
Tree data was in some cases giving you 121 of each type of curve (lists matching with tree structure...) so I worked backwards from your individual curves to flatten the inputs until ending up with only 11 (the expected number) of each type of curve.

use for some typical reasons why solar access can be important:
Solar Access for Passive Solar Heating - The conditional statement should request sun vectors for any hours below the balance point of the building (the temperature at which the building starts requiring additional heating). For residences, this can be as high as 18C and for commercial/retail buildings with high internal heat gains, this can be as low as 10C. 16C is around what you might find for some residences with better insulation and is probably the reason why that is chosen in the file.
Solar Access for Outdoor Thermal Comfort - The conditional statement should request sun vectors for any hours below the lower limit of outdoor comfort (UTCI uses 9C for this lower limit).
Solar Access for Health of Plants/Trees in a Park/Garden - This is a bit of the opposite of the other metrics since you want hours of the warmer season. In this case, I usually use solar radiation as the annualHourlyData with the conditional statement and I request hours that are above a certain radiation level (where the plants are benefiting the most). I then use an analysisPeriod to get rid of any months of the year when the trees don't have leaves on them.
Hope this helps,

explore new approaches to design in the line of Utzon's work, by extending his design principles with the use of computational techniques in a parametric design environment. The summer school is a hands-on learning environment, where theoretical knowledge is coupled with physical and digital design assignments related to the theme.
We will be working in the Utzon Center throughout the summer school and from the studies and prototypes developed by participants a 1:1 folded reciprocal canopy will be created and constructed to cover a large part of the Utzon Center courtyard.
Please send 2x A4 pages, including letter of interest (5-10 lines), 1-2 reference projects of previous work and contact details to Lasse Andersson (land@create.aau.dk) before 1. May.
