OpenNest: Introduction | #01 Nesting Objects with Text in Rhino

OpenNest 1.3.2 is a free open-source digital fabrication plugin for Grasshopper and Rhinoceros. This video is an introductory tutorial of the "OpenNest" component and the plugin in general. The tutorial also includes a short exercise for nesting groups of objects, for instance, nesting the curves and their indices as text objects. Have fun!

Now you can download a new version of OpenNest 1.3.3 with added text font option and a simple box packing.

It would be awesome if you upload videos explaining OpenNest 2. Also more importantly, you should add docs for each components and their attributes in your website etc.

Hi thanks a lot ! Very cool component and great tutorial. I noticed, trying it, that if there are too many curves for entirely fit the sheet dimension, an other sheet is automatically created, but it works only if the placement equals 0. Do you have a tip for make it work with an offset value ?

I do nesting well, but I want to know if there is a way to rotate the pieces individually after nesting.

[nathanoyoung]

Sorry I am not super familiar with grasshopper, I am getting a solution exception:object reference not set to an instance of an object when I connect the crv to the project

Nesting kitchen cabinets you have to keep track of grain direction. Can opennest do that.

[avitolourenco]

Is it possible to nest a single component until the whole sheet is occupied? or do I have to manually first make copies of the component and then feed that into the geo tab?

[nathankerridge]

please can you show how to use opennest in rhino 7 with the command instead of the grasshopper script way.

[nicolaspereda]

hey, great component, wondering how you can modify where the text appears. By default they appear in the center, but i need them to be positioned so that they don't come out of the part, how can i do that?

[Joan-oslk]

thank u! when wil it be updated? cant waiting to know the use of other componet.

[dMistri]

How we will know the part no of any object when we arrange it. i mean the algorithm just put them randomly to pack in best possible way. but lets say we have to cut them in cnc and place them on site then how we will do that.

[bdokertur]

Hello is there a way to nest a group of curves, lets say in this case you have couple of circles/holes in those closed curves.
I need to nest them with the circles as well.
How could I make GH and opennest understand with the group of each closed curve with circles in it ?
Any ideas would be greatly appreciated !

[ΓιάννηςΠαρασκευάς-φχ]

Why does it not work with circular curves?

[compassft]

I am trying to use this plugin but I get weird results...I have some shapes and if I leave rotations to 4 (so the pieces can be rotated only at 90 degrees) I get a best result than if I set rotations to 360 or even 720. That has few meaning for me...Furthermore, I could find quickly by me a better solution. With rotation set to 4 I could pack 4 shapes into my panel. But it was clear they were not in the best position. By "hand" I could pack 6...

[audreyd]

very great video, I have a question about "pack objects" as the number of planes must be equal of the number of geometry but what happens if the geometry that is cut at any frame generates 2 curves, at the end you have more geometry than planes and so it does not what to pack the geometry...I hope someone will help me. thanks in advance

[martymarine]

Hi everyone, i'm trying to nest some curves but it accepts only polylines. How can i do? (for the moment in the OpenNest geometry input i'm using ID and RhinoObject)

[lyndonhanzpernites]

Wondering about can we do custom texts?
