OPTION 2: Open your .DP scan file in Autodesk ReCap on Windows, export to .RCS from there, and then insert/attach the RCS file into your Navisworks project. NOTE: Please leave the import units set to meters during import.
NOTE: To maintain the density of your scans, it is recommended you bring the decimation down to 0 in the settings tab during both import and export from Autodesk ReCap.
