algorithmic modeling for Rhino

Hello everyone,

Here you can download gHowl_r46 for Grasshopper ***0.7.x and 0.8.x***.  This is technically our third public release of the components, though the first two have been under a beta testing stage.  This release fixes a few issues and adds some functionality not found in previous versions.  We have included examples for various applications.  If you have any questions or have issues using the gHowl components, please let us know.  Please remember to have Open Office installed for the spreadsheet components. 

*** Tested with GH 0.7.0057.  Reports show that gHowl does not appear for GH 0.7.0055.  We will sort out a compatible version for 0.7.x with the latest release.  Works well with 0.8.0001.***

These components retrieve xml data from local and web sources (such as RSS feeds).

Nice job Luis!

I really appreciate the new icons! ;-)


Nice job to the whole team!
Oh, yes, of course!!!

Sorry to forget the others!
just fixed the download link. Was linking to the wrong version.
Hi Luis,

I copied the component gHowl_r46 to grasshopper component folder, but nothing happens. There's no new gHowl tab or anything else. Do I need to customize something?

Hey Dicky, can you try to redownload the zip file and use the gha inside? Let me know if it fixes your problem. I just uploaded what should be the fix to your issue...

it workssss.. thx alot Luis

BR, Dicky
As usual Luis, awesome!

good work! was just testing the previous version with processing...
We recommend you upgrade to 0.8.0001 as a change in the way deleted objects are handled might cause errors in 0.7.x.
Hi Louis,

I work with 0.7.0055 due to other components I'm using which I'm not sure will work on later versions, just tried to use gHowl_r46 (re-downloaded it a minute ago) but components do not show.

Do you suggest me to switch anyway to 0.8?

Thanks a lot,

when did you download? If you downloaded yesterday, or very early today, try to download again now and see what happens.
