Now you can download a new version of OpenNest 1.3.3 with added text font option and a simple box packing. Download at: www.food4rhino.com/app/opennest

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 ?

[@KarthiDreamr]

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.

[@nicolaspereda7273]

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?

[@alejandrolopezposada3990]

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

[@alonsoguardado8492]

Cook the curves and then use the gimball to move manually

[@joebreaker11]

Amazing! Thank you so much!!

[@learnvisualprogramming]

Thanks for the comment, you're welcome!

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.

Why does it not work with circular curves?

[@bdokertur666]

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 !

[@bdokertur666]

Based on another tutorial, I figured out that by converting each 2D object into an extruded 3D Brep, the nesting process will automatically include circles. This way, using the Make2D command for laser cutting will work seamlessly!

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?

[@petrasvestartas4359]

Use duplicate component. It means you need to do it yourself

[@alonsoguardado8492]

You can use an array multiplier to easiliy get the number of pieces you want

[@Joan-os4lk]

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

[@petrasvestartas4359]

Hi, I am planning to do a tutorial for nesting Rhino objects in coming weeks. Stay tuned.

[@Joan-os4lk]

@@petrasvestartas4359 looking forward to your tutotial !

[@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

[@learnvisualprogramming]

Please upload the files with your question on the McNeel forum under OpenNest category, or contact us directly via email.

[@petrasvestartas4359]

Hi, the project component as the rest of components works with polylines not curves.

[@nathankerridge3039]

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

[@compassft]

I don't think it is possible. Anyway if you look the first minutes of any grasshopper beginner tutorial, you can quickly use this plugin following this video. I was completely new to grasshopper too and it took to me around 20 minutes to apply what shown in this video

[@petrasvestartas4359]

Type opennest command and properties would be the same. I ll do a tutorial for this, I promise;)

[@audreyd5240]

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

[@learnvisualprogramming]

Hi, it is difficult to understand your issue fully, so I'm making a guess here, maybe this forum thread answers your question: discourse.mcneel.com/t/issue-while-nesting-multiple-crv/153181/11 If not, please rephrase the question and contact us via email with the relevant files.

[@liams_au]

Great, thanks so much

[@martymarine5946]

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)

[@petrasvestartas4359]

Hi, You need to convert curves to polylines and nest like here kzbin.info/www/bejne/iIixaYKmf9KZpqc If you cannot figure out yourself send us an email with your geometry.

[@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...

[@petrasvestartas4359]

It depends on situation. increasing rotations might not necessary increase the quality of nesting specially when you have a small number of elements in a small sheet. Due to the speed, the nesting works by a random selection and a genetic solver, since there is always n factorial possibilities by n factorial of sheets. I assume this is your case. Then the best solution is to give a the best possible orientation initially. There are also only a certain amount of inputs given to Rhino users for example in code I can set an initial orientation + incremental rotation to avoid large rotations. There are number of possibilities.

[@lyndonhanzpernites5860]

Wondering about can we do custom texts?

[@petrasvestartas4359]

Hi, current one is the most optimized one for engraving. Do you want also option to turn existing fonts to line graphics?

[@lyndonhanzpernites5860]

@@petrasvestartas4359 actually, yes.

[@petrasvestartas4359]

@@lyndonhanzpernites5860 We might consider this option for the future release. Thank you for your feedback.

[@petrasvestartas4359]

It seems it went faster because I had to update some other things. Now you can download a new version of OpenNest 1.3.3. I added text + fonts. You can learn how to use it in example files. Also added simple box packing. F input explanation: If you do not give any "F" input, component will make original simple font. Else if you give font name i.e. "FontName " it will you this wond Else if you write "FontName 1 1" it will do bold and italic Else if "FontName 1 0" - Font Bold. Else if "FontName 0 1" - Font Italic.
