Hi melissa

Are you using a mac or pc, with some mac we expected problems with parallels, with boot-camp we never had errors.

If you are using pc, than could it be that you  had a earlier ecotect on your system?

So if yes, please make sure you had uninstalled it proper. 

geco is working only with 2010 and 2011. 

cheers,

Hi, 

after the last Rhinov5 x64 update (10 march 2011) and Grasshopper 8.0007 meshEdit stop working (also Kangaroo, gHowl stop working) the rest of plugins including GECO work perfectly (sdr, RhinoBim, WaverBird).

This is the message:

An exception occured during GHA assembly loading:  Path: C:\Users\randomHero\AppData\Roaming\Grasshopper\Libraries\MeshEdit.gha  Exception System.IO.FileLoadException:   Message: Could not load file or assembly 'file:///C:\Users\randomHero\AppData\Roaming\Grasshopper\Libraries\MeshEdit.gha' or one of its dependencies.

Thanks for your work!

Hi Andrea

so this has nothing to do with code,... i think you have just downloaded it again. The important part after downloading is to right click the *.gha and unblock the component. after that it should work fine. this is a typical solution for error 0x80131515

Hi all...

I am trying to create a clean grid on a non-orthogonal object for export to Ecotect.   The basic idea is that I've got several "floor plate" curves that define each level.  They start as rectangles but are deformed into angular plates at some points.  The curves are extruded into volumes and stacked. I am using Mesh from Surface to create a grid mesh on each surface. 

The problem is that I get these overhangs of the mesh beyond the edges of the object, which I suspect results from the UV coordinates of the surface overhanging the trim surface.  I tried to recreate using Point grid on surface and even evaluate surface by uv points but with the same results.  These overhangs are then interfering with my Ecotect calculations and are generally unsightly and incorrect.

Any tips on creating a nice clean mesh from this?  I don't want a triangulated and subdivided mesh, but something that approximates an orthogonal grid.

Thanks,

Marc

hello guys

recently i've doing some experiment with Geco and ecotect, just so glad to have this tool supporting the projects.

but now i'm kind of have wired result from the analysis of solar radiation, not sure if it's the problem with ecotect or GH definition, or perhaps my own misunderstanding!

i've posted the following files for reference, as you see in the screen the down facing mesh face of the model tend to have higher radiation values..,is this result act properly? and i should also mentioned it's the weather data of 'Belgium-Brussels.wea'

i'll be glad to hear any response! thx!

Hi,

your surface normals seems to point in wrong direction.

always make sure they point to the sky

Hi,

im having the same problem as Rex T. Can anyone please tell how to make sure surface normals to point to the sky. Thanks in advance. :)

You have to create a clean mesh.... it's up to you...you can visualize the normals  in GH with vector display or rhino with analyze direction

Hi guys

I had same problem, if you are loft-ing curves, you can just invert list before the command loft - then all runs ok.

good luck!

Hi,

I've been trying to hold off on commenting because it seems to be a common problem but I am yet to find a solution... I am using a weather file for Thailand (in the Northern hemisphere) but the South elevation is receiving more solar radiation than the North suggesting my normals are facing the wrong direction and it is calculating the gains on the inside surfaces.

I can reverse the normals if I extrude an open curve but when using a circle neither of the flip components (flip and mesh flip) work. The same goes for lofting two circles and inverting the list - good suggestion though ersilio, hadn't thought of that... Instead I get something like the second jpeg where the faces match the colour of those above and below it.

Any suggestions?

hey guys can nebuddy tell me how do u define a window component using the export mesh component in gecko for calculaating the daylight levels within a room ?

Hello everybody,

I couldn´t find this issue with a search though might be frecuent. I would like to make a solar calculation in winter and would like to know what would be the time period for the component?

Is it correct to set a domain from 356 (22th December) to 80 (21st March)?

Thanks in advance.

Discrepancy in results in Geco and Ecotect
thanks to the great plugin GECO, I'v been using geco for a while, and i found the attributes seem not same. so i download the example file named SolarAccessAnalysis, but i fund its not same either. only the peak value is same. Am i set something wrong? Confusing for this problem for several days. thank you for replying me :)
BTW: I set the SkySubDivison to 15 in Geco & Eco both.
uploaded the Attributes screenshot.
Rhino SR9; Grasshopper 0.8.0066; Geco 1.0.30.0

Hello evrybody,

I fixed my model but I'm still having problem whit the calculation of the radiation...

I have different results accord to the geometry exportation combination (see the pictures for more clarity)....

Why I have this different results?

What I should do?

Cheers!

Jacopo,

this image never can look same, because you have to compare the values not the colors. Colors are just a feedback and are remapped according to the min and max values of the calculated radiation.

best, to]

Thanks for you observation enlightened me!!!

you are welcome

Hello,

I have one question about the coloured mesh result:

is it possible to export each colours on a different layers according to the calculation value results?

cheers!

you are using grasshopper, nearly everything is possible

Do you mean bake it to different layers? Yes, but you should be dealing with values rather than "colours". There will be a far greater range of values than the 11 colours in the key - if you look at the RGB values you are inputting to your coloured mesh there are a lot more than 11 colours so you can't say group the blues, reds or whatever. You need to decide the range of values you want to group together.

You could split the mesh into 11 equal ranges which I guess would be pretty close to what you see on screen but these don't necessarily need to be equal and you could have as many or as few as you like. Alternatively you could split the mesh according to the numbers of faces you want each group to contain.

finally the results...baked in rhino and render whit vray..^_^

hello jacopo

How did you fix the sun vectore der, can u post ur def

Thanks

Hi adnane,

you can find the definition in this post...

the only thing what I did is check in Rhino the direction of the normals whit the command "Dir" and makes for alla object the same normals direction...cheers!

hello guys...

I have to fix one problem whit the normals direction for the insolation calculation...

I made in grasshopper a double facade system made by  lots of sunscreens geometries when I baked the geometries they doesn't have the same normals direction...

how can I change all the normals direction in a specific one?I don't wanna select manually each geometries and flip it...what i should do?

Cheers!

Hi Jacopo,

you can try to use the unify normals component from [uto]'s MeshEdit plug-in or you can also try to use the orient component from the transform tab.

Hope one of this is helping you, otherwise it would be better if you could also post your definition or the rhinofile.

Best,

Martin.

I saved the calculation results in Rhino as a joined mesh, now I would like to group "lots" polysurfaces by mesh colours?

How can I do that?Cheers!

I hope you saved the calculated values.

You can create a cullpattern according to the solar impact values with some key values wich are important for you and create your groups with that (smaller than)

hope this helps

Thanks for the help,fixed!

hello..

i currently have the grasshopper 0.8.0052 and geco 1.030, but everytime i try to connect gh to ecotect, the button "ecolink" turn red..and show me the message above.i don;t know why. my ecotect is 2010...i will appreciate if you could help me ...

Hi Thomas

please install geco proper and donot just copy the files to to your folder.

thx

thank you for the help!!!

Hello to all,

this is my thesis project, experimantation whit geco and grasshopper

I am having trouble wiring up more then one mesh. I have attached a sample problem. Shouldn't the base surface have less radiation where the top surface is obstructing the view to the sun?

Hi John, I think the problem is how you made the two surfaces / meshes...Try to make two surfaces in rhino and then selected this from grasshopper...should works fine see the pictures... ^_^ you should check also the normals with the command -> dir

cheers

Hi Jacopo, thank you for your direction. It turns out that I can create the meshes through 'Mesh UV' although the normals were flipped, strangely they work when normals are pointing down. I am a little confused why this would be. Any insight would be welcomed.

I also am having trouble reloading results from Ecotect after rhino times it out. I have read the solution many times but it doesn't work. Any suggestions?

Another question, when do you create many instances of EcoMeshExport? If I have two surfaces should I use two instances of EcoMeshExport? Using one instance works for SolarRad, I would assume you would use multiple for applying different materials to different surfaces, but when is that applicable? What sort of Calc?

Lastly, Thank you to Geco for an awesome tool! Looking at Ecotect's interface makes me dizzy! Its also incredible that we can build on initial setups and chunks of code, collective knowledge prevails!

Hi Jon,

Please post such message in the Geco-User Problems so everybody has a benefit and the threads are sorted to the according plug-in.

Ecotect defines the meshnormal with the right hand order so the meshnormal does not count in this case (counter clockwise)

1: if you want to reload just rewire the ecolink and then the component you want to refresh.

2: many instances are used for different materials or for surrounding buildings and terrain

Thanks for your feedback and welcome to the group

Hey, is it possible to export geometry to ecotect but use it just for blocking ligh, not to perform an actual analyse on it, just as an environment.
