Thanks for the explanation on the rabbit. It seems that I will seek some mesh on standford website.

just started learning grasshopper.

give me some info on nice video tutorials. 

i bought "Parametric Architecture with Grasshopper - Primer guide", currently shipping from Rome.

Italian architects good at Parametric Design?!?

Hi, I download the new version and it works. The component is producing the list the surface separately. Then I apply them to my roof design. Thank you!

Giulio grazie mille dell'amicizia, appena mi viene in mente qualche suggerimento te lo posto anche se devo confessarti che il tuo plug-in ne ha bisogno di pochi, complimenti!

Un saluto,

Thanks Giulio,

I thought it was developed with WB's catmull-clark subd. but for me that result is uncontrollable, but I like the result anyway¡¡

Thank you again, you rule¡¡

Hi giulio, great fan of yours¡

If you don't mind, i've got a question:

How do you control the mesh in your model (in your own web, see below) so it is arranged where it's possible? I mean, It is a regular mesh('ordenada' in spanish) in the main building and become irregular in the union...

Maybe this place is not the right place to ask you directly, please forgive me if not...

this is what I get:

thank's so much

Hey man, without your rendering block there would be no tutorial, so thank you. Take care.

No problem Giulio.  I'm always happy to plug's been a great tool.

Hey Giulio, big fan....

Was wondering if you have an updated version of baking numbers as curves for the 0.7---- series?
At 11:00am on May 6, 2010, Zach Hines said…
Giulio, sorry I asked to early... It dawned on me that I could just link it with another one of your naming components... Thanks!
At 10:46am on May 6, 2010, Zach Hines said…
Hi, Guilo, wanted to say thanks for the great components!

Also, I had a question about your Bake Attributes component. I want it to bake my object name in this format: obj(123) and it currently looks like this: obj123

Is there a way to add the () before and after the number?
