Hello, I need assistance in trimming a lattice to obtain the resulting mesh inside a cube. I’m providing the outcome of a mesh difference operation where I’m using the inner lattice mesh as the first input and a cube as the second input. Could someone please guide me on how to achieve the opposite …

Hi @Supriya this looks like a difficult case. Without the model, it’s hard to give many suggestions. Have you tried this in Rhino 8 WIP? All mesh boolean commands are rewritten. Thanks, Giulio – Giulio Piacentino for Robert McNeel & Associates giulio@mcneel.com

Hii @piac This is stl file of the model result.stl (3.1 MB) .Both mesh are there. I am working with rhino7.

You can try with Dendro [image] Rhino 8 WIP (free at the moment) seems to work but not solid. [image] BUT your lattices are awful/bad not joined not touching … So garbage in => garbage out Dendro could save you here.

[image] This is Rhino 8 BETA work to create sharp cuts. Step 1: Shrinkwrap to obtain a single solid mesh (You can do this in Dendro afaik). We need to get rid of the fragile overlaps [image] Another option, which I leave up to you, is to precisely match vertices and then join faces, without f…

Thanks @laurent_delrieu its working fine

Thanks @piac we will try this one.
