Hi, I am developing OpenNest to achieve better packing efficiency. Could you share datasets in Rhino (simple geometries, not Grasshopper scripts), specifically: Sheets Polygons you are nesting I’m particularly interested in the cases that are the most problematic or difficult to achieve good nesting efficiency with. I would love to receive this information to train a model to capture border cases. Thank you!

Nice @Petras_Vestartas, I would like to see the result of this. [image] OpenNest for Rhino8 - plugin update OpenNest @Petras_Vestartas thank you for this upcoming update and everything that comes with it. pray:t2 I reported this a long time ago. I am still curious about the result of these kind of shapes… [SharedScreenshot] ToNest.gh (151.7 KB)

Hi @Petras_Vestartas I will send you this in DM, 135 pieces of Pat Def table [image] There are sheet of 600 x 600 mm and 400 * 600 mm. A professional tool gave me this MagPie Nest [image] [image] I didn’t go too deep in Open Nest with this one as I have a very good packing, but I’ll have new jobs and no more access to MagPie. For this type of geometry I began to make some simplification tools (suppress some holes, offset 2 times to smooth …).

I have a side request that has nothing to deal with nesting complexity :slight_smile: when a Time in seconds is supplied to the OpenNest2 → Nest Options component, at the start of the nesting an external window pops-up and asks to confirm that value (or insert a different one) [image] I sort of understand the reason why it’s designed like that, but I would love an option to bypass that window (I don’t know… an option that could be activated in the right click menu?) the reason I’m asking for this is: I’m experimenting with Anemone to supply seeds to OpenNest, in such a way to generate dozens of nesting solutions, and evaluating the best one afterwards having that window popping up at each Anemone Loop doesn’t allow anything different from Time=0, which is a single Nesting iteration, otherwise at each Loop cycle you should confirm the nesting time :slight_smile: I know it’s stupid, but if this window-bypass is something simple to implement I’d really love to play without it!

Thanks for noting this, yes it is only user interface option. I will change this. At the moment it is only like that. Good to know also that you dealing with multiple seeds to explore options.
