In fact I used the copy/paste method (cmd-c cmd-v) suggested by dxli (see his Jan 20 message) ,
it is much simpler in theory.

Lukily enough I found a provisional way to get access to all my frozen entities by erasing
the dimensions from the AB receiving drawing (one by one).  
A conflict with the intermediary format transported by the C invaders ???
