Navisworks is a native file of Navisworks® project review software by Autodesk.
Navisworks files come in three formats: NWD, NWF, and NWC. An NWD is a single file that contains all model geometry, environment, viewpoints, and review markups. An NWF file is a list of links to the original files. It doesn't keep model geometry and, to be opened, requires access to the original CAD files. An NWC is a cache file created from any native CAD or laser scan files, when opened in Navisworks.
JT (Jupiter Tessellation) is an ISO-standardized 3D data format and is in industry used for product visualization, collaboration, CAD data exchange, and in some also for long-term data retention. It can contain any combination of approximate (faceted) data, boundary representation surfaces (B-Rep), Product and Manufacturing Information (PMI), and Metadata (textual attributes) either exported from the native CAD system or inserted by a product data management (PDM) system.
In 2012 JT received a status of international standard ISO14306.
JT files are used in product lifecycle management (PLM) software programs and their respective CAD solutions, by engineers and other professionals that need to analyze the geometry of complex products. JT extension and associated software is structured so that extremely large numbers of components can be quickly loaded, shaded and manipulated in real-time.
Because all major 3D CAD formats are supported, a JT assembly can contain a mixture of any combination which has led to the term "multi-CAD". As JT is typically implemented as an integral part of a PLM solution, the resulting multi-CAD assembly is managed such that changes to the original CAD product definition files can be automatically synchronized with their associated JT files resulting in a multi-CAD assembly that is always up-to-date.
CAD Exchanger supports all recent versions of JT which are most broadly used in industry from JT8 to JT10.
A CAD file is an output of a CAD software, containing key information about the designed object: its geometry and topology representation, 3D model hierarchy, metadata, and visual attributes depending on the format of the file.Read more
