Hi Arthur,

first of all i would recommend you to delete one of the kangaroo.gha (they are twice)

As i can see you are using a old geco release (it should have 150kb--> yours 62kb)

maybe you check the version number or you just download the actual release

cheers

Tom

Thank you so much Thomas! It works now.

I got the order wrong and installed Geco for GH 6 :S

All the best,

Arthur

Hi uto,

I am now trying out the SolarAnalysis example and found problem when working with multiple surfaces. See the attached image 2. It looks fine on the Ecotect analysis but somehow the color shown in Rhino is different. I suppose it is a problem of mapping the values? I could not figure out why, please help.

Eventually I would like to use this plugin to analyse a typical residential tower in Hong Kong and make changes to it.

1. single surface. Rhino receives correct value from Ecotect

2.multiple surfaces. All 4 faces are purple on Rhino.

3. input for multiple surfaces

Thank you very much,

Calvin

Hi uto,

I need to refine my problem. I understand now I should not use Mesh Surface for a BRep even if I explode it. By meshing the BRep instead, how could I sub-divide each face on the BRep in the same UV manner? In that case I could analyse a particular storey from a building.

Please assume I have the outline of a floor plan and I am thinking to extrude it to get the facade surfaces.

Thanks again,

Calvin

Hi Calvin,

sorry for the late reply,...

attached the file you are asking for.

if you have any question feel free to ask

Hello all,
First, thanks for the wonderful tool you guys developed. I am a beginner in grasshopper as well as GecoGh and enjoying/struggling with these powerful plug-in.
I have a problem with insolation calculation component.
I wanted to run different types and metrics of insolation calculation, but keep having some problem which I can't figure out any solution for.
The attached file has a room with glazing at front and I want to run solar access test on glazing surface. In insolation calculation component, as you know, there are different options to select;
Available insolation calculations [C], and Metrics [M].
The problem is that in the attached file I found no matter what I chose between 'Incident solar radiation on Points & Surface' and 'Solar Absorption/Transmission of Object Surfaces' in [C], or between 'Total incident Radiation' and 'Total Absorbed Radiation' or 'Total Transmitted Radiation' in [M], The resulted values fed back from Ecotect to grasshopper seemed always to be 'Incident solar radiation'.

Would you be kind enough to take a look at the file and see what my problem may be?
I've used version

GH08.0050

Rhino 4 SR8

geco v1.025

Thank you so much!

Hi Joo Suk,

Thank you for your post and your feedback, very much appreciated!

So one problem in your definition is that you are calling the wrong ID numbers. So the color you are applying to the glazing mesh are the one from the walls. After correcting this fault everything will work fine. Take a look on the attached file and images.

Also be aware about exporting the mesh. with your settings you are creating again and agin the shading geometry inside the file when you change something

cheers,

Hi guys,

It is hardly to belive me that this subject wasn`t discussed till now but I can`t find an answer.

It seems to be easy task - I want to connect the size of overhang with galapagos and chack which size is optimum, but i can`t find a way how to get only the values from the window (i.e. direct solar radiation) by changing the size of the overhang?

Thanks

Hi,

two meshexport components

one for windows and deselected in ecotect after export

one for the overhang with [n] set to 1

but be aware that your solution will just try to enlarge the overhang as much as possible until no sun reaches the window anymore. You will have to come up with a design-criteria to get something out of it

Hi to],

Firstly, thank you for the amazing geco components!

Secondly I am using the 'shadow studies interior' example file and I am wanting to calculate the total area of the internal shadows. I have switched the 'change shadow' boolean toggle to false so that the shadows are now coming out as a planar surfaces projection. Then I attempted to use the 'trim with region' component to trim the shadows to the inside of my room. This worked for trimming the curve, but then I couldn't create new trimmed planar surfaces to calculate the area of the interior shadows.

Any ideas on how to set up the definition so I can calculate the total area of the shadows projected into the interior space?

Thanks
