Help! Trying to cut out 3D mesh using mesh trim - Rhino for

Hello, I am trying to cut out a 3D mesh of a lattice structure using the “mesh trim” tool. My end goal is to have cut out a 3D mesh in the shape of a cylindrical disk with a defined diameter and thickness. I have attached my Rhino 3D model. I have tried to setup a 2d circle curve but not sure how to setup it up properly. I am curious what would be the best method to achieving this? Thanks! Daniel Lattice Structure.3dm (899.0 KB)
