na upresnenie posielam kod.

1. v pripade ze v pripojenom vykrese sa nachadzaju objekty s layer = 0 SelectionSet po query vrati objekty s layer = 0. Ak sa nenachadza, vrati  vsetky objekty z predchadzajuceho SelectionSet-u.

2. taktiez v danom pripade nefunguje Query.Execute, ale iba ThisDrawing.SendCommand "_MAPWSQUERYEXECUTE "
