Generative Algorithms - Porous Structures

hi,

i try to explore for me the tutorial "POROUS SHELL" by zubin m khabazi.
http://www.grasshopper3d.com/page/tutorials-1

Unfortunately I have overlooked something in phase three,
and the result is not gratifying.
maybe someone has also made this tutorial,
and can draw attention to my fault.

that would be very nice.

as you can see, the edge MidPts and some circles are not created!

this must be like the picture above.

Hi Rassul,

The problem lies with the very first CP component You need to graft the List going into C.

dear danny,

Your note solves the problem with the missing circles.
remains the question, why the centersPts of the curves
can not be created, so that the circles get more points to be created.

many thanks.

p.s. maybe someday I can spend a couple of beer? (:

I've finally worked it out. The Graft answer earlier you can ignore.

What you need to do is explode the radial curves before selecting them in GH. (best way to do this is select your 5 curves Rhino Explode but leave them selected, then in GH set Multiple curves and it will reference the preselected ones.)

Then (and this is the important bit) Select all of the curves from this mesh in the first Curves Param. That way the definition will include them in the mid point routine. At the moment its just working out 4 curves instead of six because it doesn't know to include them.

One day our paths will cross, no doubt.

I'm going to be very drunk one day on all the GH community beers that have been bought for me :)

dear danny,

I think you've been drinking today.(:

I make the files available if anyone needs it.
thank you to mr. boyes!

There's just no pleasing some people, huh. :)

These two gaps, which I was blind to, must be as a result of the dispatching based on a tolerance maybe play with those settings.

Interesting though, I re-grafted the original input and got rid of the gaps but the process took 776 seconds to complete so I would suggest that this is not the solution.
