I need to keep the holes in the same position as in the Boundary Surfaces. I don’t know why my data structure is a mess. I pulled the curves, lofted, countour, boundary surfaces, extrude and solid difference. [image] banco parametrico.gh (28.3 KB)

there are many examples in this forum on how to nest the proper way using opennest, consider also upgrading to opennest_2, which would make things a bit easier I’m using opennest_2 so I can only give you some hints, but the general thought is always the same: once you have succesfully created your …

I can’t internalize it. I’m importing some control point curves from Rhino. Is there a way I can do it anyways? [image]

right click on this and chose “internalise data” [image] after that, do the same also with the other component then save the gh file with different name and reupload it

I noticed that there are some intersections. I don’t know if it’s due to my version of Open Nest. I tried to solve the problem this way. For convenience I used a Pufferfish component, but you can use Bounding Box. [image] [image]

the problem with that approach is that you won’t take advantage anymore of any cavity a shape has, which translates into waste of sheet area I reverted my opennest_2 installation to 1.5 to see what’s going on, the problem comes from the nesting curves not having a good point distribution so, for i…

I had the same problem but the same approach did not work unnamed.gh (7.1 MB)

all looks fine in the last version of OpenNest2, you can decrease the simplify tolerance if you want nesting borders to be more precise (if you notice small compenetrations here and there) or increase Spacing [image] unnamed_inno.gh (7.1 MB)

Thanks man I had to unnistal and install it again so I could get the new version of OpenNest. But in this new version I did not find a way to put IDs in each piece

you can take advantage of the Transform data for that [image] first you create IDs in the form of text of some sort in such a way they lie on the original surfaces in A (make sure the text/numbers lie inside the outline of each piece) then you can combine together the Transform data from of the …
