it within the same smart umbrella? Or put it differently: is it worthy to exploit/consider/evaluate GH methods and development orientations that could "approximate" Utopia?
Let's split the case into segments:
The parametric part thing (although critical) is complex and rather beyond the scope of GH. Affects Rhino far more than GH. That said Microstation has 3 levels for doing this (but forget Microstation and/or Gen Comp).
So for a start we can focus in GH acting as a "composer" in 3D place of all the required (hopefully real) parts for the job. Parts must be nested AND readable as such by an external AEC app.
I'll post here (soon I do hope) all the parts that are required for assembling this. I mean individual static "blocks" that we assume (wrongly) that remain static: I mean we presuppose that the whole GH geometry is fixed (thus this is really a smart sketch of some sort) and no further changes are on schedule (that MAY affect parts).
That said I prefer an incomplete Utopia (one thing that "does" it all, or it thinks that does it) than a myriad of individual apps that take input one from the other and promise the Holly Grail (and/or delivering it). The core reason that I use Microstation as my basic platform is exactly that (obviously with a certain price to pay: bugs, shortcomings, wrong concepts in places etc etc etc).

b, then tried again, but I still have no luck. So what I did is I modeled the building again in Rhino and reduced the curves then I imported the geometry into GH and used the HoneyBee zone by surfaces component , but I noticed that after I grabbed the new components I get a "NULL" if I plug a panel to the final zone. Finally I decided to model a very simple box and grab all its surfaces to create a zone , and to my surprise I still get "NULL" Am I doing something wrong ? here are what I did to create this one zone box
1- modeled a 3d box in Rhino
2- Exploded it
3- In grasshopper I created HB-surfaces ( Floor, Ceiling, 4 individual walls and added I glazing by ratio to one of the walls)
Here is an image, also I attached the file, the box components are grouped with an orange background. Now I'm convinced that I have a bug or something because it can't get easier than creating a zone from a simple box and yet I get a "NULL" message.

acting as the height "guideline"? (section in Z so to speak). If so has any meaning using sliced portions of spheres and then attempting to bridge them? (I mean: is any reason for an exact arc [per shell] as a footprint?).
2. By grid shell you mean that you want to create a truss "following" the resulting brep? [polysurface if we bridge the 2 cells]. What type? (MERO: meaning struts/balls, FLAT: meaning a geodesic collection of struts/connectors or ABSTRACT: some kind of "liquid" thingy with/without W "thickness"?).
3. Is this a building roof/canopy/hangar/whatever of some sort?
4. Is this academic?
5. By "not that advanced in C#" you mean that you have some serious plans to learn the language (path to hell that one, he he) or you are just curious about?
6. If in the forthcoming V2 some stuff is performed via C# (meaning terra firma for you - at least at present time) could be that a critical issue?
7. Do you have GH TSplines 4 (Beta) installed? Are you familiar with that thing? (and the numerous bugs as well).
8. If Kangaroo could called on duty (Plan Z) for the upwards "morphing" job (starting from a "flat" mesh approximating an uneven figure of 8 ... etc etc) could be that an issue?…
information that you desire. Just set zoneEnergyUse and zoneGainsAndLosses on the component to true and you get the equipment load (equal to equipment gain), internal lighting load (equal to lighting gain), the people gain, and the total solar gain. If you also need window heat loss, you can get this on a window-by-window basis by setting the surfaceEnergyAnalysis to true (and, after the simulation, use the 'Surface Data Based on Type Detailed' component to pull out just the window data from the list of al surfaces).
2) There was a bug in the otherZoneData of the 'Read EP Result' component when you set the "normByFlrArea" to True. Thanks for finding it. I fixed it in the attached GH file so that you can get those specific Zone-level outputs if you want them instead of what I have suggested above.
3) There is currently not a component to read meter outputs mostly because this information would be misleading with the 'Run Energy Simulation' and it use of an ideal air heating/cooling system. The energy from ideal air systems is not factored in meter outputs and you need to specify a complete, real HVAC system for such thermal outputs to affect things like meter electricity or meter fuel. Now that development is picking up on the OpenStudio component, which can write these complete HVAC systems, we will eventually have a new result reader that parses the E+ SQL output (including meter outputs).

s a WIP component and there may still be bugs in it. Copying the zone geometry first and then creating the zones may be a safer option.
2 - YES! Honeybee can handle the curved surfaces as you can see but you will cut down your simulation time 100-fold by planarizing your geometry in an intelligent manner.
3 - If you were only building a single test box model, making the interior and exterior two separate zones would probably be the most accurate and would allow you to asses many different surface temperatures and heat flows. However, if you are trying to model a full building like this, you are better off simplifying the whole facade down into a single construction or else you can end up with really long calculation times.
4 - If I were you, I would only simulate one floor at most. In this case, you want to make the boundary condition of the ceiling and floors adiabatic. The simplest way to do this is to pass the zones through the "Make Aidabatic by Type" component and check the boundary conditions with the "Decompose Based on Boundary Condition" component.
5 - You are mostly correct except that direct sunlight turns to diffuse light after passing through the SECOND WINDOW that it hits (not the first and not a pane of glass but a full window). This allows you to accurately model things like double skin facades as separate zones.
Hope this helps,
-Chris…
and maybe the last 10 or so that I have created
1b. I also like the idea of shades of color and some preset color swatch libraries like Rhino has or being able to load our own.
2. I mostly use the color picker for setting the color of groups to organise files. Again here swatches would be so great, because I hate having to always eyeball it to get the same color or set it as default just to create several groups with the same color.
2b. Related to that is that please please pleeeaase let us edit more than 1 group at a time. Why cant I select several groups and set a color at once? Actually all group functionality should work with several groups and not just the one I right-click over. Using the Edit > Ungroup when having multiple groups inside a larger group selected also doesnt work and creates some sort of visual bug - I just noticed it now, will post separately.
3. The color picker should also pick transparency from other groups and not the actual on-screen pixel color, so that I can use the color picker to recreate the color of another group. Right now this isnt possible as groups are by default somewhat transparent, so if I pick a color it always comes out several shades darker.
Thanks for considering and keep up the amazing work!…
easy. There is room for discussion and clarification. The most wanted ideas quickly, and clearly, rise to the top. Voting is limited in a clever way and forces users to choose their most valued features.
The general rules, copied from: http://3dsmaxfeedback.autodesk.com/forums/80695-general-feature-requests/
Each user has 20 votes for each forum
Each idea can have no more than 3 votes by a single user
If you enter an idea, it will cost you 1 vote – therefore try to make sure the idea doesn’t already exist
The more precise and detailed a description you give, the more likely your idea will be considered
When an idea is implemented (or declined), votes are returned to all the users that voted
Users can change their votes at any time
Admins can move, edit and delete ideas as they see fit to better meet the goals of the forum
We will flag ideas that are getting our attention as “under review”. Because of limits on what we can say publicly, that is as far as we can go with commenting on a particular idea. If it is “under review” it simply means we’re studying it for possible implementation or gathering data, but there is no commitment to do it.
