3D CAD software innovations Autodesk's Digital Prototyping tools help engineers and designers experience their 3D CAD designs virtually, before they are built. By connecting every phase of your design process through a single digital model, our Digital Prototyping solutions let your teams test and optimise 3D CAD designs, helping to drive innovation, achieve higher quality and speed time to market. Our Building Information Modelling (US site) (BIM) software gives designers and engineers an integrated way to explore a project's key physical and functional characteristics digitally. Through the use of an intelligent 3D model to inform and communicate project decisions, our BIM solutions deliver insight and business value for building design, construction, infrastructure and utilities projects.
