I was able to get this wonderful model of a beer can with accurate dimensions : https://www.cgtrader.com/free-3d-models/household/other/aluminum-can-high-detail-16-oz , but I want this object to be a solid so that I can utilize the boolean difference function. Does anyone know how I can do this?? My rhino 3d modeling knowledge is limited but I have a project i'm working on that I'm excited about and this would really help!
