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,

ay how many valid permutations exist.
But allow me to guesstimate a number for 20 components (no more, no less). Here are my starting assumptions:
Let's say the average input and output parameter count of any component is 2. So we have 20 components, each with 2 inputs and 2 outputs.
There are roughly 35 types of parameter, so the odds of connecting two parameters at random that have the same type are roughly 3%. However there are many conversions defined and often you want a parameter of type A to seed a parameter of type B. So let's say that 10% of random connections are in fact valid. (This assumption ignores the obvious fact that certain parameters (number, point, vector) are far more common than others, so the odds of connecting identical types are actually much higher than 3%)
Now even when data can be shared between two parameters, that doesn't mean that hooking them up will result in a valid operation (let's ignore for the time being that the far majority of combinations that are valid are also bullshit). So let's say that even when we manage to pick two parameters that can communicate, the odds of us ending up with a valid component combo are still only 1 in 2.
We will limit ourselves to only single connections between parameters. At no point will a single parameter seed more than one recipient and at no point will any parameter have more than one source. We do allow for parameters which do not share or receive data.
So let's start by creating the total number of permutations that are possible simply by positioning all 20 components from left to right. This is important because we're not allowed to make wires go from right to left. The left most component can be any one of 20. So we have 20 possible permutations for the first one. Then for each of those we have 19 options to fill the second-left-most slot. 20×19×18×17×...×3×2×1 = 20! ~2.5×1018.
We can now start drawing wires from the output of component #1 to the inputs of any of the other components. We can choose to share no outputs, output #1, output #2 or both with any of the downstream components (19 of them, with two inputs each). That's 2×(19×2) + (19×2)×(19×2-1) ~ 1500 possible connections we can make for the outputs of the first component. The second component is very similar, but it only has 18 possible targets and some of the inputs will already have been used. So now we have 2×(18×2-1) + (18×2-1)×(18×2-1) ~1300. If we very roughly (not to mention very incorrectly, but I'm too tired to do the math properly) extrapolate to the other 18 components where the number of possible connections decreases in a similar fashion thoughout, we end up with a total number of 1500×1300×1140×1007×891×789×697×...×83×51×24×1 which is roughly 6.5×1050. However note that only 10% of these wires connect compatible parameters and only 50% of those will connect compatible components. So the number of valid connections we can make is roughly 3×1049.
All we have to do now is multiply the total number of valid connection per permutation with the total number of possible permutations; 20! × 3×1049 which comes to 7×1067 or 72 unvigintillion as Wolfram|Alpha tells me.
Impressive as these numbers sound, remember that by far the most of these permutations result in utter nonsense. Nonsense that produces a result, but not a meaningful one.
EDIT: This computation is way off, see this response for an improved estimate.

asuring Urbanity."
The seminar aims at re-centering the debate of measuring urban form on the contemporary issues of designing, planning and regulating the extensive city. It will bring together a group of international experts on the subject and the objective is to discuss the importance of combined qualitative-quantitative approaches on the generation of new insights on the contemporary urban environment and planning strategies.
The workshop presents a set of innovative approaches and methodologies using its own software. At the workshop participants will be invited to use the available toolset to address a specific urban issue where the construction of models for automatic measurement of urban indicators will be part of the urban design process.The workshop is intended for all urban planning professionals who want to improve their skills and knowledge as well as for students or doctoral students in urban planning. The CIAUD will issue a participation certificate equivalent to 3 ECTS credits.The workshop will run from 7 to 12 May 2012 and the seminar will be held on May 11, 2012 in FAUTL.The seminar and workshop program can be found attached ora t the website: http://www.measurb.org/en/home.html We thank in advance for the dissemination of this event to whom might be interested.

r [String Split] in version 0.9.0014)
The [Timer] prompts a component to up date at the set interval. in this case every 1 seconds.
The [Time] param is a placeholder for a time in the same way that a [Number] param can hold real numbers.
By using "Now" as the input to the [Time] param you will get the current time when the param updates. therefore every second it resets to the current time.
The [Text Split] is there to separate the output of [Time] in a string format at every colon ":"
Therefore "Monday, 13-MAY-2013 (11:23:30)" would become:
0 Monday, 13-MAY-2013 (1
1 23
2 30)
The next two components use this to convert it into the current seconds. Because we are after the last item "30)" we can use [List Item] on a reversed list to get the last item.
Now we have to remove the ")" with [Replace String] but we are replacing it with nothing so it disappears.
The Arrow is part of the Sketch Tool Functionality of the canvas.
Lastly the 3 different inputs should go into the three different Inputs of the [Stream Filter]

you post a screenshot of what the message coming from its readMe! output looks like?2) Close your Grasshopper and Rhino.3) Download "Revo Uninstaller Pro" from here. It is free for first 30 days, which is what we need.4) Right click on the RevoUninProSetup.exe and check if the file is blocked. If it is, unblock it.5) Run the RevoUninProSetup.exe file and install "Revo Uninstaller Pro".6) Uninstall "MapWinGIS" with "Revo Uninstaller Pro". It is important that "Revo Uninstaller Pro" deletes not only files from MapWinGIS installation folder, but also all other leftovers (as registry inputs). Here is a small tutorial on how to do that. Watch it from 6:10 till the end.7) Restart your PC8) When your Windows boots up, make sure that you are logged in as Administrator!9) In your Start menu's search box type: "UAC", which will find your User Account Control Settings. Click on it, and a new window will open. Set the bar on the left to "Never notify".10) Turn off your Windows Firewall.11) Then turn off your custom Firewall (in case you have another one, besides standard Windows Firewall).12) Completely turn off your Antivirus.13) Download again the MapWinGIS-only-v4.9.4.2-x64.exe.exe file from here.14) Right click on the MapWinGIS-only-v4.9.4.2-x64.exe file and see if it is blocked. If it is, unblock it.15) Right click on MapWinGIS-only-v4.9.4.2-x64.exe file and choose: "Run as"... Administrator.16) One the installation preparation steps start, choose "Full installation". Wait for the MapWinGIS installation to finish.17) Right-click on "Rhino 5" icon and then choose: "Run as administrator".18) Open the the ironpython_admin.gh file again, and again post a screenshot of the message coming from its readMe! output.19) Drop the "Gismo Gismo" component to Grasshopper canvas. Post a screenshot of the message coming out from its readMe! output.
So we will need in total three screenshots of the readMe! output messages.
Thank you once again for being patient, and sorry for the large number of steps.…
