Hello

We are having the same situation and also looking for such a soft that could split automaticaly large parts on a smaller sheets and nest them. No succses till now. If you split manualy and than nest with Rhino ist quite ok. But it takes a while to understand how to give info correctly to a program.
What kind of soft you are using now for your nesting of a large parts?

Hi Guys

To date we have been manually nesting in Autocad, drawing a string of the individual panels and laying the parts over the top.
We were hoping that there is a program to take some man hours out but like you the search is coming up empty.

Hy

We are also doing all the spliting and nesting in autocad. Is saves some time if you use rhinonest but anyway if you need to change some detail splitting you go back to acad an again to rhino . Its too much mess.

Hi,

This is an interesting question. The answer for RhinoNest 2.0 is you must to split it by hand! But we can developed, the question is what criterion we use? Any ideas?

Thanks,

In our case we are producing foam parts for windblades. So if you imagine windblade shape size about 50m lenght and 4m width. Sheet size about 2x1m. So we need to split balde into small pieces to fit sheet size nesting. Criterias should be as less details as possible, max material usage, Spliting should be done in sipliest forms: rectangular or tarpezoids. It would be very useful that you can easily modify splitiing manualy. Also our material is with some special groovings so orientaintion is importan also.

Hello,

I was thinking these days about it! And after to do some test, I think the best option is a tool to divide objects AFTER the nesting, becuase the optimization is better.

What do you think about to do a nesting using a sheet of 100m x 4m and then split it automatically by sheets of 2mx1m? Does it make sense?

Thanks,

I have the same problem, but I manually nesting in the Catia V5 with large and small objects using the same sheet.
I make a grid with the sheets and I studied the best fit manually, then cut the objects larger than the sheet, these objects can not be cut anywhere because of the amendment, and the cut must always be perpendicular and / or parallel with the object.

 If i use a big sheet to nesting then cut, it will cut unnecessarily the small objects, and can put objects in the center of 4 sheets, that can use just 2.

Having to save material.

I hope this information helps you develop this tool.

Thanks
