Hi Ivo!

I found an old thread about a Diagrid on a surface with aparture openings of different sizes.. (I think it was from 2010). I would be so grateful if you could send me the definition (or a screenshot of it) if you still have it, I have been struggeling for days now to make those openings.. It would be really helpful!

My email is:

Thank you so much! 

With regards

Hi Ivo .....thanks for sharing your excelent tutorial.

It is quite clear, so i was able to replicate the definition in an hour or so.

some questions:

-i wonder if its possible to reduce the amount of components....specially shifts and branches, using the path mapper

-the folding amount has a certain maximum value...right?

it would be nice to be able to calculate that exact maximun value....before the components start to deform.

Thanks again
