altitudes of the crude... how to put them?

[Pliskin]

Hello.
how can I quote the loft's crude in c.a. If I put up a 10cm floor package that is a floor on your own?
positioning it I try to use the tab button but always selects me only the level suppresses the finished floor I would like to quote both in a single plant with different symbols to indicate the two levels:- share of the structural crude (solar in c.a.)
- share of the finished architectural floor (floor with finishes)
grazie, andrea

for the finished use "view altimetric quotas": upper altimetric quota (from the bar of options)
for crude use "visualize altitudes": lower altimetric quota (always from the bar of options)
