"Autodesk® Navisworks® software for manufacturing allows you to experience real-time fly through and walk through your digital factory models. Combine together product data, tooling & fixture data, layout and facilities data from different CAD formats and create a single 3D digital model of your factory. Analyze the model to check for collisions and identify space constraints. The digital factory model can also be published in a highly compressed lightweight format and shared with suppliers and partners to give all stakeholders complete access to the information."
