ace when I start running Galapagos/Octopus (below is "room orientation optimization" shared at http://hydrashare.github.io/hydra/viewer?owner=mostaphaRoudsari&fork=hydra_1&id=Room_Orientation_Optimization&slide=0&scale=1&offset=0,0) It may take quite some time to see some results. That's fine for the above simulation. But my real challenge is, when I am going to optimize room dimension with respect to ASE and sDA calculations, either Galapagos or Octopus goes wildly and never come up with a solution. I believe the time-consuming calculation, especially sDA with higher -ab numbers, trigger the lag a lot? Any suggestion/trick to improve it?
Most importantly, based on your experience, for example to optimize window/exterior shades sizes and achieve ASE<10% and sDA>55% (LEED v.4 requirements), Octopus (due to its capacity of multiple objectives) is the only choice? Any other approaches within grasshopper?
The alternative approach in my mind as a GH beginner is as follows. But I am not sure whether it is doable. Again, your comments will be greatly appreciated.
Since all my room/window/shades dimension are controlled by number sliders, I am thinking whether a component from GH will trigger these number sliders (not necessary to be all of them but one by one) automatically. If this is possible, I can do "data recorder" to record outputs from ASE and sDA. Eventually I will have a database of the input parameters and sDA/ASE results.
Does it make sense? Is there a component which can trigger number slider output at certain step?
Many thank!

Il workshop avanzato ECOLOGIC PATTERNS affronta l’impiego di strategie parametriche all’interno del processo progettuale, approfondendo l’utilizzo di Grasshopper in sinergia con plug-in, software di analisi ambientale e simulazione fisica. Obiettivo fondamentale è la generazione della forma come risultato di tecniche di form-finding e di input ambientali (solari, termici e acustici). Verranno acquisiti nuovi strumenti operativi e di simulazione al fine di costruire modelli parametrici ottimizzati in grado di adattarsi a diverse condizioni di contesto.

ort and export from the images below and also from the HELP file of DB in attachments (Page 71: Importing Geometric Data; Page 78-80: Import 3 - D CAD Data). In their HELP file, they mention about "import geometric data".
However, regarding the input of schedules, loads, constructions and etc., DB normally uses "Component " and "Template" (Page 29: Templates And Components; Page 591: Templates; Page 533: Components). "Templates" are databases of typical generic data, including Activity templates, Construction templates, Glazing templates, Facade templates, HVAC templates, Location Templates, and etc. "Component " are databases of individual data items (e.g. a construction type, material, window pane).
Both "Component " and "Template" are allowed to be imported and exported by using "Import / Export library data" command (.ddf format - DB Database File; Page 734: Import Components/Templates, Export Components/Templates). DB also allows us to build up our own libraries of templates and components (Page 731: Library Management; Page 733: Template Library Management).
In order to import both geometric information and other information related to schedules, loads, constructions and etc. from GH to BD, we supposed the following two ways:
1. GH(HB+GB) --> gbXML (both geometric and "Component " and "Template" information) --> DB
This is the way we most prefer. We did see information related to schedules, loads, constructions encoded in the gbXML file generated by GB, but still do not know the reason why DB did not take this information (I also mentioned this in Q6 within the gh file). We assume this might because the gbXML file we create encodes the schedules based on a different template / schema than the one DB expects. We also post this question to the DB forum for help.
(http://www.designbuilder.co.uk/component/option,com_forum/Itemid,25/page,viewtopic/p,13755/#13755)
2. GH(HB+GB) --> gbXML (geometric information only) + .ddf ("Component " and "Template" information only) --> DB
If the first way doesn't work and DB only takes geometric information from the gbXML, then we might think of the other way - generating the .ddf files from GH(HB+GB) to pass the schedule, load and construction information to DB.
I was wondering if it is feasible for HB and GB to have this function? And what is your suggestion to achieve this?
In addition, we notice that DB can export XML files (not gbXML), so we are trying to figure out if DB also accepts / reads the XML file. If so, we might be able to convert the gbXML (with both geometric and schedule information) to XML. What do you think about that?
Thank you again for all your help!
Best,
Ding

thing that MicroStation does (or doesn't). The eternal debate between us is that they focus to the so called BIM aspect of things (and obviously on interoperability matters - that said IFC2*4 is" implemented" in certain Bentley verticals like BA and others) whilst I'm after assembly/component puzzles (and on that matter ... MS ...hmm... to put it politely is not exactly CATIA and/or NX, he he).
On the other hand this paranoid obsession with Level/Layer driven CAD (I hate it) defines a red thick line between CAD and MCAD - because the most intelligent importer can't emulate the way that Siemens NX/CATIA classifies objects - and without control power means nothing.
On the other hand Microstation V9 (...soon) has interesting scripting capabilities (think Modo rather Generative Components) ... meaning that Grasshopper could work there in a rather nice way. I think that I must talk for that to Ray (he recently ditched the ancient legacy MS render engine in favor for the Luxology/Nexus engine). Ray still is negative to buy Act3D mind (hope that you know the mother of visual scripting - the Quest3D VR thing).
On the other hand - within the broad AEC aspect - things these days are different (especially in fast developing countries the likes of UAE, Saudi Arabia, certain ex USSR "democracies" etc etc). Studies are outsourced even at Preliminary Design stage to various sub-contractors (they undertake the Study completion per discipline as well). This means that N separate groups doing M aspects of the whole ... meaning entropy^(N*M) - that's chaos in plain English.
With this in mind I'm quite (a lot) skeptical about the practical meaning of the whole exchange thing in AEC - at least with regard the countries mentioned (not to mention that several portions of a modern AEC thing are made via MCAD apps - chaos^chaos.
I'll back with more focused issues on that matter.
But the big question is: Grasshopper of Generative Components? Well...let's talk serious SS bikes instead: think a Ducati 1198 and a BMW S1000RR (I have them both): which is "best"? The thing is that not always the best bunny is the fasted bunny and not always the fasted bunny is the best bunny.
