  ProGtoldataStatus lStatus;

  lErr = ProGtoldataTypeSet(lGtolData , xGtolType , &lStatus);

  ProSelection lpSel;

  lErr = ProSelectionAlloc(NULL , &xEdge , &lpSel);

  lErr = ProSelectionViewSet(lView , &lpSel);

  lErr = ProGtoldataReferenceSet(lGtolData , xRefItemType , lpSel , &lStatus); 

  lErr = ProGtoldataPlacementSet(lGtolData , PROGTOLPTYPE_DIMENSION, &xDimension , NULL , NULL , NULL,    &lStatus);

lErr = ProGtolCreate(lGtolData , &xGtoL);

lErr = ProAnnotationShow(&xGtoL , NULL , lView);
