This relationship definition is used during the conversion of a file to a .pdf file or to any other alternate rendition, as well as during the generation of WebGL viewer files (.binz and .vecz). It has a linked interface, ISPFAlternateRenditionInfo, that has properties to determine the application that will perform the conversion process. These properties are not required for generating WebGL viewer files, but you must have Intergraph Smart® Interop Publisher 2017 R1 installed on your SmartPlant Foundation File Server. For more information, see File Service Settings node properties.
The SPFFileTypeFileType relationship definition supports multi-staged conversions.
