The file reader supports ReCap files.
The ReCap file formats are RCS and RCP. RCS file format is a single point cloud that incorporates all the scan files that have been imported into the project. RCP file format is a project file that points to the individual scan files and contains information about them.
This file reader differs from other file readers supplied with Autodesk Navisworks. Instead of converting the contents of the ReCap file and including it in the model, the file reader makes a link to the RCS/RCP file and adds this information to the model. The file is loaded on demand as you navigate around the model. The advantage is that the files open almost instantly. The disadvantage is that you need to keep hold of the RCS/RCP files - even after publishing to an NWD file.
