This report describes Computer-Aided Design (CAD) model-viewing technologies1 used to support CAD-model review and analysis. CAD model viewers are tools that allow engineers and other users to view CAD models from distributed locations, often using lightweight viewing applications, often supporting multiple CAD formats. These tools are typically less expensive, faster, and simpler to use than native CAD systems for model review. These features are especially important for small and medium-sized enterprises that can not typically support multiple native CAD systems. Additionally, considerations when choosing a viewing technology are described, as well as, popular CAD-model file formats that viewing technologies can import.
