The design application SketchUp is a powerful software that can help you generate complex 3D models. Architects, engineers, and designers use it when creating a basis for their projects. However, models created using the SketchUp app is not easily shared. The person you will be sharing the design with will need to have the app to view the design exactly as it is. It could be a costly use of resources when you only need to see and analyze the design. Luckily, Trimble, the brains behind SketchUp, created SketchUp Viewer, a program that will let you view SketchUp model designs as they were, as well as share the designs easily. This design tool allows users to access a 3D model design, whether they have access to SketchUp or not.
