I won't get the parameters of standalone annotation (wfcGTol, wfcWDimension, etc). If I call function ListParams() or GetParam() by annotation (wfcGTol, wfcWDimension, etc) object it gives exception as a toolkit error.
We had raised the case regarding this and PTC replied "for a standalone annotation, a visible Annotation Element does NOT exist. Only an internal Semi-Annotation Element exists. There are No public Creo Toolkit or OTK C++ APIs currently available". So could you share API to access parameters of standalone annotations?
