OpenNest using Sheets with holes (feature wish)

[Patt]

It would be great if OpenNest could work on sheets with interior cutouts/holes. The sheets could be input as a flat surface and interior / exterior curves could be sorted out internally in the component to keep inputs simple.

In the current plugin, the ‘sheet’ shape on the left works, the one on the right would not.

I’m actually looking for this feature to help place annotations on parts and avoid cutting holes, but I’m sure the feature would be handy in lots of applications! Thanks for an amazing plugin.

P.S. What engine does open nest use? Is it this one? https://deepnest.io/

Hi @Patt,

There is a “Transform” output which coupled with Grasshopper’s “Transform” component can be use to orient the holes along with nested outlines.

I do often use the transform output, I don’t know if it’s relavent here.

This is what I’m trying to describe;

Hi @Patt,

Sorry for the misunderstanding.
I don’t think this is possible.

Here’s another link describing a useage case

The only work around I can think of is to split the initial sheet into single loops before starting. The downside is that the shapes avoid crossing the ‘join’ lines.

If you don’t need a real nesting, you can use that, as it is mesh it allows holes …

Nesting randomly (sort of Wordle)

Here some words inside other words made with a script that deconstruct a shape in an array of bool. [love%201] [love%20bunnies] [love%20bunny%204] [Love2] [image] [love3] [Sans%20titre%202] [effectsResult] There is no optimization in it. It uses some brute force but is quite fast, 1.5 second for 100,000 runs and 1000 pixels minimum. Not a very clean script at the moment nesting words V2.gh (66.2 KB) It answer a question of @luiscarlospp

I have done a nesting tool using the same logic, but it is far for being released

Thanks for the reply @laurent_delrieu , I’m a big fan of your scripts from the forum over the years (the sand dune generator is great!).

I look forward to the nesting tool, the code certainly handles this use case. I only wish it didn’t duplicate the shapes to be ‘nested’ as it is currently. Thanks!
