Hi Evert,

here there was a small example: http://www.grasshopper3d.com/forum/topics/c-question?commentId=2985...

Sure, in most cases you just need to know the type ( here DataTree<double> ) and then use the intellisense-like features or the SDK help file to discover methods and properties.

I hope it helps,

Hi Giulio,

I finally had some time to look at the link you kindly posted and here are my results. Is this the way it should be done? I took GH hexagrid component to look at the paths and manage to renumber the indexes to be similar.

Would you or anyone else mind having a look at my definition?
Cheers
Evert

Hi Evert,

compliments, the script really works nicely!
This might be a start with the tree structure... it's actually easier in a completely programmed component.

Also, I had to switch U and V in the loop.

Hi Giulio,

Thanks for looking at my script and making it better, It is now much clearer to me how to deal with paths and trees.

I'm now looking at given the centre points and frames at centres as output so I'll work based on your file.

Many thanks again.
Evert

BTW I had to open your file on texpad and copy/paste inside my component, it gives an error while trying to open your file.

Mh..., I dont know why about the errors: are you using Grasshopper 0.8.1?

Hi Giulio, Yes I'm uisng 8.001.

I've added the centre points of the cells. Definition attached!

Is there a way to make the centre point function simpler or the whole thing simpler.

I mean if a function can return more than 1 value?

I'll start setting up this to create a component I hope you don't mind me keep asking 8)

Many thanks
Evert

To return more than one value, you could use the out parameter.
Not sure if it will make the function simpler.

Hi Giulio,

Your last message is indented too deep to reply. I had forgotten about the msdn site, I'll keep that in mind!
Many thanks for replying, I think I can use the out parameter to output surface frames at centres points and the centres perhaps.

I'll look into it.

Cheers.

Evert
