rsity building with 81 thermal zones. I wanted to use this model on my master thesis, but I am afraid I won't be able. So I would really appreciate some help.
The purpose was to set different insulation thicknesses and glazing types depending on the orientation. Therefore I created every zone by using "createHBsrfs" components. At the same time different zones would have different "building programs".
I created all the zones, I added windows as "child surfaces" for every zone. And I created the adjacencies. No errors or whatsoever.
But from this point I cannot connect the model to any other component without GH being frozen. So although the model is correct maybe it is to heavy for the software, however I am not sure if that is the reason.
Is it stupid what I have done? Is there any easier way to accomplish my purpose?
Any thought or help will be much appreciated.
I attach the GH file.
Thank you,
Eduard

assume we want to format two numbers, one integer and a floating point value. The integer represents an index and it should appear inside square brackets, then we want the floating point number rounded to a maximum of 4 decimal places (but always using at least one decimal place, even if it's zero), and then, in parentheses a scientific notation representation using 8 decimal digits of the number.
So, assuming the index is 16 and the value is 47.280006208, what we are after is:
[16] 47.28 (4.72800062E+001)
To make this work, we need a formatting pattern that looks like:
[{0}] {1:0.0###} ({1:E8})
The square brackets, spaces and parenthesis are just part of the output, they have no meaning whilst formatting. Everything inside the curly brackets though will be replaced with a specific formatting of one of the values.
When using the Format component as shown above, the formatting pattern is just text data. The component knows that it is supposed to use the Format() function using the pattern text and whatever additional data is provided.
When you invoke the Format() method in an expression, you do need to make sure that the pattern is actually text:
So here the pattern needs to be encased in double quotes, otherwise it will be treated as code, rather than text.
You cannot use the formatting method in the internal expression of a number parameter, because this method returns text, whereas the number parameter is only capable of storing numbers. Any expression that you put into a number parameter had better return numbers as a result.…
e some questions.
I want to loop with a foreach loop trough a list of points do i have to make a list before or is it possible to use them coming in from a noed i set the access to list?
Also i dont understand why no plane is created. How do i need to feed the points in?
And why is c# expecting open parens in line 88 and 86?
Hope its not to much at once, probably i should try a few less steps to get the problems solved one by one, just hoped it would be easier and sometimes just a parentesis is missing or some format stuff, so maybe it is not so much i really cant say.
If anybody has the time and feels he wants to help it would be nice on the other hand i understand cause of the amount of chaotic questions.
Regards!…

a variety of interesting objects, from abstract fractals to plant-like
branching structures, their modeling power is quite limited. A major
problem can be traced to the reduction of all lines to integer multiples
of the unit segment. As a result, even such a simple figure as an
isosceles right-angled triangle cannot be traced exactly, since the ratio
of its hypotenuse length to the length of a side is expressed by the irrational
number √2. Rational approximation of line length provides only
a limited solution, because the unit step must be the smallest common

√2
denominator of all line lengths in the modeled structure. Consequently,
the representation of a simple plant module, such as an internode, may
require a large number of symbols. The same argument applies to angles.
Problems become even more pronounced while simulating changes
to the modeled structure over time, since some growth functions cannot
be expressed conveniently using L-systems. Generally, it is difficult
1.10. Parametric L-systems 41
to capture continuous phenomena, since the obvious technique of discretizing
continuous values may require a large number of quantization
levels, yielding L-systems with hundreds of symbols and productions.
Consequently, model specification becomes difficult, and the mathematical
beauty of L-systems is lost.
In order to solve similar problems, Lindenmayer proposed that numerical
parameters be associated with L-system symbols [83]. He illustrated
this idea by referring to the continuous development of branching
structures and diffusion of chemical compounds in a nonbranching filament
of Anabaena catenula.
The following is an example of its application:
starting string: A
p1: A F(1)[+A][-A]
P2: F(s) F(s*R)
which I think is basically trying to say
F(s) = move forwar a step of length s > 0.

milar once its default data managment techniques are exceeded thus forcing a new address index to be inserted. Its all just so unnecessarily particular and finickity.
If addresses are added when forced to, why not just have that as the default behaviour in the first place? Its not so much 'one size fits all' as postulated previously, but more one size fits 80% of cases and in the remaining 20% of cases you're going to be a slave to your definition as constant manual management will be required just to control the thing.
My final point:
circle with points should have a list address of {0}
multiple circles with points should have list address of {0;0}
multiple circles in multiple locations with points should have list address of {0;0;0} etc
I really dont see how that is any less consistent for highly complex data strucutres. To any rational individual this is predicable and follows a logic. What advantage is there in fixing the address at {0;0} yet still allow for new address sequences to be added firther down stream? Logic is the key thing to keep in mind here, not peculiar nuances only the initiated can ever be aware of.…
cle
the 'Shape' is copied to all points
shapes are rotated randomly, plus or minus 'Angle' maximum
'Shape In Brep (ShapeIn)' is used to cull shapes that aren't within the circle
'Fast Loop' begins using 'MCX' (Multiple Curves Intersection)
first shape is added to 'D1' output and shapes intersecting it are culled
results minus first shape are passed to 'D0' of 'FastLoopEnd'
loop repeats until 'D0' list is empty
'D1' results are scaled down slightly (0.75) to leave more space around them
'Explode' results and return only the curved part, ignoring the base line that closes the shape

avid--this software is a pleasure to use, and David, you have done an amazing job. I also want to acknowledge it takes a lot of work to edit the software, and I understand that it can take a while before any changes are made.
Okay so here are some ideas:
Subcurve - just like subsurface, but based on 1-dimensional intervals
Map Values to Interval - a single component that could take a list of values, an interval, and would scale the list of values to match the input interval.
A Dispatch component that could dispatch according to a list of output indices. Instead of just True/False, you could output things based on a pattern using 0/1/2/3/4, etc. This component would be the inverse of Weave.
A text object parameter and data type, with some basic ways to edit it.
More string manipulation operations, allowing for easy editing with string subintervals, and character counts, and basic text formatting (line return, etc.).
I really really really wish the List Item component had a default index value of "0". That is what I input into it 80% of the time.
That's all for now. If any of these ideas are already adequately addressed, please let me know. Thanks.

ellation tool of GeomGym in Grasshopper.
The design looks for a new brick topology which is in the shape of two generative elements of Weaire-Phelan structure; dodecahedron and tetrakaidecahedron. An innovative approach is taken by applying varying types of solutions and details to the new brick elements.
There are other good examples and winners which are worth looking into. Our sheets can be downloaded from here.
All comments appreciated.
We would like to thank Jon Mirtschin and anyone who contributed to this tool.

on this, but to my understanding, the Δt_pr used is the same - the equations used to calculate are not. Take a look at this (from EN 7730 as well):
If I can make some wishes too; it would be cool, if you included the last local comfort metrics from EN7730 in LB/HB as well. Besides the local asymmetry there are: an equation for warm/cold floors, stratification and draught. I know, that you will need preform a CFD simulation to properly calculate stratification and draught, but the comfort equations are really simple and seeing that you have(might have) a CFD tool under way it could be useful. Anyways I think it would possible to import external generated CFD data to grasshopper.
The pictures in my previous post are from a paper called: "A simplified calculation method for checking the indoor thermal climate" by B.W. Olesen, it can be found in ASHRAE 1983, vol. 25, issue 5. I don't know if there have been any updates to it since '83.
Looking forward for the new components, and if there is anything I can help with please let me know.
