Nesting in partitions

Grasshopper OpenNest
1

Hi all,

I often work with large numbers of numbered pieces that need to be nested and then sorted again after cutting. At the moment, the nesting result can spread related pieces across the entire sheet, which makes sorting and assembly quite time-consuming.

Is there a way in OpenNest to partition a list of objects into batches, for example groups of 20 pieces, and nest each batch as a separate group? Ideally, each batch would remain spatially clustered on the sheet, while still being nested efficiently within that group.

I was wondering whether this can be done by using Grasshopper data tree branches, or whether OpenNest treats all input objects as one combined set regardless of the branch structure.

I tried with a simple voronoi structure, but no succes..

The goal is not necessarily to get the absolute most efficient sheet usage, but to keep related pieces close together for easier sorting and assembly after cutting.

It is possible, but I need to develop that…

Hi Petras,

Thanks for the quick feedback. That makes it clear — good to know that partitioning the data tree is not a viable approach here.

No problem, I’ll work out a more semi-manual workflow, probably by nesting smaller sets separately and arranging those results afterwards.

Thanks again!

A possible solution?

Thank you!

In the future version, I will add this options for the other components too:
