Rick, very soon now that will be quite easy if you're willing to write some code.
However, until the new release is out, you'll have to struggle on. It will be quite difficult to connect the correct points if the input is a grid of points on the surface. There's a lot of combined looping and if-ing required which is not something a visual editor does well. See: http://grasshopper3d.googlegroups.com/web/SwissCheese.png?gsc=iMIg4RYAAABnjvYb5Wy5iHwHmp3rLCVfsJrAtjd9Fq-fV8M8HcFQDQ I divided the surface up into small surfaces. Then I got rid of every other surface in the grid by using the [Cull Nth] component. Then evaluated all those surfaces at {0,0} and {1,1} (after setting the surface input parameter of the evaluator to 'Reparameterize') and connected those points with lines. I cannot give you the file because I'm using a new version of Grasshopper which has a different file format and no longer saves the old format... sorry. -- David Rutten Robert McNeel & Associates On Oct 10, 12:34 am, rick <[EMAIL PROTECTED]> wrote: > i'm basically trying to remodel the swiss-re building aka 30 St Mary > Axe a radial tower building in london. i need to create a diagrid, > which is basically a triangular system. so i'm trying to figure out > how to connect the bottom floor plate to the top floor plate with a > line that shifts over to the right at every floor plate creating a > spiral to the top. the width of the floor plates change as you go up > the tower. as the floor plates begin they start to widen as you go up > but, reach the maximum width at about the 18 floor from about 39 > floors. after the 18 floor plate the floor plates start to get > smaller all the way to the top. so i need to connect the floor plates > with a line that shifts at every plate (like a diagonal) i then need > to create that same effect going the opposite direction so it creates > a diamond effect. it's similar to the shift example on the wiki > tutorial which only connects two floor plates of the same width. i > need to connect multiple floor plates of different widths but i can't > figure it out. any suggestions?
