NWF files are used to aggregate other cache or delivery files together with the necessary information to store clash detection, issue management and 4D planning operations, among others. Metadata regarding 4D planning, assemblies, viewpoints, issues, etc, is contained in NWF and NWD files. Cache files are usually stored with their corresponding native files but this is not mandatory.Ĭache files are not designed to be modified after created, on purpose. If the source CAD file changes, a new conversion is triggered. Contain geometry and properties for a converted model.Ĭache files are the main piece of information in the Navisworks workflow: other CAD formats are read by Navisworks translators and a corresponding cache file is then created. Navisworks is capable of directly opening dozens of different CAD file formats but internally it always works with the same three: NWCĪlso called cache files. Is the complete solution, all tools are available. It allows the use of the timeliner tool for construction planning, but not the use of the clash detective tool. You can view the objects hierarchy and their properties and also edit them. This product allows you to combine and display multiple models simultaneously. However, edition is restricted and the model cannot be modified at all. It allows navigating the model, accessing saved viewpoints and comments and making measures, also playing an existing 4D simulation. Is the free-of-charge viewer version and only allows opening one NWD, 3D DWF or Recap file at the same time.

Navisworks is offered in three versions: Autodesk Navisworks Freedom Navisworks Manage combines spatial coordination with construction planning, allowing the simulation and analysis of it, and also you can manage the changes that occur during the construction progress. It allows us to anticipate, prevent and resolve problems in the virtual model before construction begins, to reduce costs and minimize changes and delays. Main usesĬlash Detection: Interferences detection and management. It allows shared viewing and review of models of different disciplines (Revit, Inventor, Rhinoceros, Solidworks, Sketchup, Allplan, Robot, CYPE. It is an Autodesk software that enables the analysis, simulation and communication of design and constructability. User has basic skills in BIM modelling with Revit Software, and understand the language used.To understand what Navisworks is and how to convert Revit files.
