Problem installing gHowl

Installing gHowl is like installing any other add-on for grasshopper.

1. Download the add-on and examples from food-for-rhino

2. Unzip

3. Drag the 'gHowl_r50.gha' found in the downloaded and uncompressed file onto the grasshopper Canvas - you should now see a gHowl tab.

If you still have issues, let me know.

Luis,

Thanks for your response. I tried the steps you mentioned. I downloaded and unzipped the folder and found the 'gHowl_r50.gha' file. But when I try to drag it to the gh canvas nothing happens.

Any suggestions?

Thanks,

you do not get a gHowl tab?  Which version of Grasshopper do you have? 

You can also go to File -> Components folder

and copy that gha file into there and restart Rhino / Grasshopper.  See if that does it.

Luis,

Thanks very much. that worked just fine. I have build 8.0066.

Now I gotta learn how to use it! Are there any tutorials on how to transmit categorized data into excel?

Thanks,

Yavar

Ok, if you are working with spreadsheets, you will also want to install the OpenXMLSDKv2.msi that you find in the 'Dependencies' folder after you uncompress the gHowl zip.

In the gHowl examples there are some definitions in the 'Spreadsheet' folder to get you started.  The best thing to keep in mind is that each data tree branch will act as a row in the spreadsheet.  So if you have a list of 10 items, you will get one row with 10 columns.  If you have 3 branches with 10 elements in each, you will get three rows with 10 columns, etc...

Best,

Luis

Hi Luis,

Thanks for your help so far. I have made some good progress in the past few days. The gHowl exercise files were really helpful. Now I have a very specific question. But I should first ask you this; should I start a new discussion if my question is unrelated to the prior questions in the thread? If so, I will do that from now on.

Now, my main problem is this:

I am designing a parametric box for which 30≤x≤420, 30≤y≤270, and 30≤z≤300 and they are all increments of 30. My approach was to define ranges for x,y, and z and use them to create a domain box. What I am really after are a complete set or list of every  possible box within my domains, which should be 14x9x10=1260 boxes. Instead I only get 14 boxes resulted from the N'th  result for x,y,and z. I know I'm missing somethings in the definition which would enable that, but I don't know what! I have uploaded what I have so far. Could you tell me what steps I should take to get the result I want?

Thanks,

I was thinking last night and I found a big flaw in my guess for the number of possible boxes. What I have calculated is only the number of boxes with

x, y, and z = 30. The total number of possible boxes in the defined ranges, which have edges being incriments of 30 is much larger than1260. It will definitely be more than 4 digits. I am not sure but perhaps it is 14! x 9! x 10!. Does that seem right?

And if you think my approach is not right for the grasshopper definition, please disregard it and tell me how I can acheive the desired data. (I thought maybe bound box would be the answer).

Thanks,

Hi,

I want to install ghowl add-on for grasshopper.

Unfortunately, I cannot find the file: ghowl_r50.gha in the uncompressed file.

What should I do?

Steps I do:

1- press the zip button in this website:

https://github.com/gHowl/gHowlComponents

2- download the file as a zip

3- uncompress the file

4- I cannot find the file!

thank you,

You want to download from the food4rhino.com link: http://www.food4rhino.com/project/ghowl

The github link is only for the source code.  Food4rhino has the compiled component.
