class AcDbPointCloudDefEx : public AcDbObject;

AcDbPointCloudDefEx.h
Description
The AcDbPointCloudDefEx object (or "point cloud extension definition object") controls the actual point cloud data associated with one or more AcDbPointCloudEx entities (or "point cloud extension entity"). These objects link the .rcp/.rcs file to the dwg file, similar to how Xrefs work.
The relationship between the AcDbPointCloudDefEx and AcDbPointCloudEx classes is much like the relationship between an AutoCAD block definition object and a block reference entity.
AcDbPointCloudDefEx objects are stored in a special AcDbDictionary named "ACAD_POINTCLOUD_EX_DICT". These objects are not AutoCAD entities, so they can't be displayed or selected by the end user.
