Convert NWF to PRE

Understanding NWF and PRE file formats

NWF files are Navisworks File Set files used by Autodesk Navisworks, a project review software for architecture, engineering, and construction. NWF files store references to design models, viewpoints, and review markups, but do not contain the actual model data. Instead, they act as containers pointing to the original CAD files.

PRE files are less common and can refer to various formats depending on the software. In the context of engineering and construction, PRE files are often associated with Primavera Project Planner (P3) as project export files, or with other project management tools as pre-processed data files.

How to convert NWF to PRE

Direct conversion from NWF to PRE is not natively supported, as these formats serve different purposes and are used by different software. However, you can export project data from Navisworks and import it into Primavera or another project management tool that uses PRE files. The typical workflow involves exporting schedules or model data from Navisworks in a compatible format (such as CSV or XLS), then importing that data into Primavera to generate a PRE file.

Recommended software for conversion

• Autodesk Navisworks Manage: Use Navisworks to export project data. Go to File → Export → Reports and choose a suitable format (e.g., CSV).
• Oracle Primavera P6: Import the exported data using File → Import and select the appropriate format. Primavera can then save or export the project as a PRE file.
• Online converters: There are no direct online converters for NWF to PRE due to the proprietary nature of both formats. Manual export and import is the most reliable method.

Tips for successful conversion

• Ensure all referenced files in the NWF are accessible and up to date before exporting.
• Check the data mapping during import into Primavera to ensure all fields are correctly aligned.
• Consult the documentation for both Navisworks and Primavera for supported export/import formats.
