To ensure the best results assessment on the data and the type of data being published to iModel, there are several prerequisites needed for each file type. For example, all Revit data needs to be geospatially located to the correct location prior to publishing, all point cloud data needs to be pre-processed, all Reality data needs to be using the correct Geo-Spatial coordinate location to ensure data alignment. Also, users need to do an overall data quality check to ensure there are no failures using the iTwins connectors. There are also several prerequisites to using ESRI GIS data within iTwins as well as other data types such as Navisworks, TEKLA, Rino, Trimble, and IFC.
