Okay, it's will be usefull. But as I understood, the device values for spacers 
and prelaminary device<->XYZ dependency in *.ti1 will be the same. In this case 
the problem with spacers can still presist.
I ask gamma for whole the device space, even for -f patch generator (at least 
at first step before prelaminary profile).
