This sample demonstrates how to create Point Cloud engines for Point Cloud represented by 3 dimensional cells. Engines can be categorized either file based or non-file-based. In this sample, 3D cell representation in a xml file is used for a file based engine and hard-code cells for none-file based engine. Three interfaces IPointCloudEngine, IPointCloudAccess, and IPointSetIterator must be implemented for an engine. The engine has to be registered to Revit. Revit interacts with an engine through these interfaces to display, select, snap, and perform other operations on the point cloud. The sample also shows how to export the point cloud to an external file.
