I’m a beginner in GrassHopper.
I’ve been looking for an answer for several days, but I couldn’t find it.
I created a parametric shape based on this video.
Everything went smoothly here.
Then, using the Ivy plugin, I took a single ‘burnt’ element and unroll it.
I got a lot of unconnected curves this way - how can I select all generated objects and then place them in OpenNest? (I can’t put unclosed curves there.)
Sorry if my question is understandable. I don’t know a “professional” language yet and fully English
Unfortunately, I don’t have Rhino 7 to be able to open your files, but if I try to do the same in Rhino 6 using one of the Ivy examples…
If you use the Ivy “Piece Arrangement” component, you can take the C output (the cut lines), join them, and nest those. You can then use the “Transform” output of OpenNest with a Transform component to move all of your original flat curves to match the nested position of the cut lines.
(Please ignore the section labeled “Ignore Me” - I had to omit some of the data from the Ivy Example because certain curves weren’t closed - this just let me put the example together quickly)
Sorry about that. Probably a different version of OpenNest for R7.
The basic premise should work, though. Create joined curves of the outer cut lines generated by Ivy, nest those, then use the transform created by OpenNest to shift the original curves.
