Waffle system: dividing curves into "puzzle" segments.

Hi guys, i've only started playing around with grasshopper a few weeks ago - so bare over with me :)

Basically i'm doing a school project. My definition is based on manipulating the topology of a grid of points with attractor points - this works fine :)

Secondly i've gone through lift-architects' waffle system definition, and that also works well.

Now, a new challenge emerges :)

The wood panels we're going to mill, arent bigger than 240mmx120mm - so basically the struts i want to cut, cant fit onto the panels.(Check jpeg) So what i have to do is somehow dissect(yellow lines) the whole structure(with the waffle system applied ofcourse) and make smaller pieces(Check red circles). After this i have to make some kind of a puzzle(Check puzzle jpeg), so i can assemble the pieces again.

So my question is, how do i approach this? Im thinking of intersecting the whole structure with planes, move them apart, and then find the the regions of intersections, and somehow draw a puzzle-system onto the respective (intersected)struts.

Any help would be appreciated :)

Thank a bunch!

Hi Ivan! great tutorial thanks! I've reached the tutorial 1/4th, and already i'm encountering problems :/

I started out using one of my struts(before it gets oriented onto the xy plane for cutting), i've drawn a line(the line is oriented with a z-vector) on it, and started using this instead of a line thats already baked in rhino(as his is).. 5 min in his tutorial, he rotates some points - pretty basic - but my points won't rotate..

I have no idea why, i've tried flattening, cleaning tree etc. - nothing works...

I think it's because i altered a bit in his way of doing it, because my line is oriented in z-axis, and my circles are oriented in the y plane.. But i can't see why this shouldn't make them able to rotate?

Could any1 solve this puzzle? :)

The problem will appear on the far right of the definition..

Thanks a bunch!
