Flow around object

Hi everybody,

I was wondering if someone can help me out with the following:

I found a definition on http://formularch.blogspot.nl/2013/06/gh-flow-around.html for let a curve flow around a object, but I still don't get my definition the same as the definition on the site above, or the picture I uploaded. I guess it has something to do with another version of grasshopper.

I marked the part of the definition I can't do. It is not possible for me to give the "pull point component" two inputs on G. Maybe somebody can help me out with this?

Another question is, is it possible to get just one curve as output which flows around an object?

Thanks in advance!

Paul

Hold shift to give multiple inputs. Just use one line to get one curve.

Hehe true that! But it will take more time i guess;p

Well i hope you won't get crazy of me, but ill ask you something about the flow around definition. I tried to let a curve flow around more then one object, but the curve won't flow around more then one object. Maybe you can give me a tip to fix it?

Thanks again

set multiple objects. You should really read some books and stuff on the tutorials page as this is really basic stuff.
