In Grasshopper, I’m trying to loft a series of curves (824) created from a combination of Voronoi diagrams. The issue is the curves aren’t lofting to the closest curve but rather a seemingly random one, creating geometry that looks like a ball of yarn. I’ve tried rebuilding and dividing the curves, closest points, and pull point with no luck. Hoping to avoid having to manually loft all 824 curves. See below screenshots. Any ideas would be greatly appreciated!
EDIT:
Showing lines connecting points in lieu of the loft because it crashed my iMac.
Did you reference these loops from rhino model?
GH doesn’t know which one should be lofted with which. You’ll have to make your own proximity test of some kind. You’d get better help if you uploaded a file.
That is what I’ve been trying to figure out and have been wildly unsuccessful. How to tell Rhino or GH to loft to the closest shape. Rhino file attached.
I referenced each set of loops as a group front and back.
Thanks for the love, to me it seems to be in very short supply…
I’ve spent an absurd amount of time trying to make a solid (holed) wall using these lofted curves. I finally succeeded using an extremely SLOWSDiff component with 1,646 holes, but not before purging a couple of duplicate curves (yellow group) that fouled all efforts for quite awhile.
The ReB(Rebuild Curve, cyan group) is optional but seemed to smooth some of the holes. The Reduce component (white group) is for testing with a value of 0.98 on the ‘reduce’ slider (blue group) to minimize the painful 15 to 22 minute delay of SDiff. (ouch!)
Using the painfully slowSDiff was a last resort in this case, after trying many alternate methods that involve joining the lofted curves with two holed surfaces and the wall edges. All failed.
This is great! One question, if I want to replace the void pattern with a different one. Do I “set multiple” all the void shapes for both curve nodes? Or are there a few more steps to it?
I don’t understand what you mean? It should be a straight-forward replacement of the two curve params (the holes and the edges). Remember that yellow group was added to remove duplicates, which should never have been there in the first place.
Some of the complexity in this model could have been avoided had I selected the curves from the Rhino file more judiciously, or treated them as two holed surfaces (below, yellow group). The two duplicate curves may still have caused trouble but that’s a separate issue.
