This is the code:
<CODE>
var pip=op->GetPolygonCount(); if (!pip) return TRUE;
for (i=0; i<pip; i++)
     {
     var poly=op->GetPolygon(i);
     var p1=int(p[poly->a].x);
     var p2=int(p[poly->b].x);
     var p3=int(p[poly->c].x);
     var p4=int(p[poly->d].x);
     if (p1==0 && p2==0 && p3==0 && p4==0)
          {
          var vc=new(VariableChanged);
          var h,map=new(array, pip);
          for(h=0; h<i; h++) map[h]=h;
          for(h=i; h<pip; h++) map[h]=h-1;
          vc->Init(pip,pip-1,map);
          var ok = op->MultiMessage(MSG_POLYGONS_CHANGED,vc);
          op->SetPolygons(map);
          op->Message(MSG_UPDATE);
          }
     }
     
return TRUE;
}

</CODE>

Tnx for answer!

Try this code with SendModelingComman()

    
    
      
    
    
    
    var pip = op->GetPolygonCount() ;
    
    
    
    
    var pt = op->GetPoints() ;
