The structure is clearly defined in the SimConnect header:// SIMCONNECT_DATA_XYZstruct SIMCONNECT_DATA_XYZ{ double x; double y; double z;};So, just define a structure of three doubles (64-bit floats), and pass its address where you'd normally pass the address of your single double or integer or whatever.RegardsPete

Well, to start with, the structure types can only be used with specific SimVar names (for the XYZ, there are around 10 that use that format, LATLONALT has about 5). Second, you would create a variable in your data structure using the full SimConnect data type name (ie "SIMCONNECT_DATA_XYZ myXYZVar;") and do one AddToDataDef call for that field using SIMCONNECT_DATATYPE_XYZ as the data type.Also note, some of the SimVar structure types (Waypoints, InitPosition) are only valid when used with SetDataOnXxx, they aren't associated with any readable variables and can't be used with RequestDataOnXxx.
