Please see the attached file for my part. I want to put in an extrude cut that cuts off the "Mesh" portion in the little rectangular cutout. For some reason, when I do the extrude cut and choose the selected scope (so that only the linear patterning of mesh gets cut), it includes the bottom structural member even when I am only clicking on the mesh.
Does anyone know why this occurs or how to fix it? I've done it successfully before, not sure why it is not working now. Only the mesh should be getting cut from that part of the body, not the structural member as well.
