set flat variant

[aedoardo]

with pro-e wf3 to set a variant as a flat state I used the command file/set/lam/state piano and automatically created the file: e.g. filename_flat1.
how to do this same operation with creo paraemtric 1?
Thank you very much

the command to create the flat variant is: file/prepara/property model/lamiera/varianti flat condition;
my problem that the option "variant flat status" does not appear to me.
Thank you.
