# Let us open a small idf file that has only "CONSTRUCTION" and "MATERIAL" objects in it.
# You can go into "../idffiles/V_7_2/constructions.idf" and take a look at the file.
# We are not printing it here because it is too big.
#
# So let us open it using the idfreader -
# <codecell>
#name and volume of small zones
namevolume = [(zn.Name, zn.Volume) for zn in smallzones]
print namevolume
# number of small zones
print len(smallzones)
print smallzones[0].Name
print smallzones[1].Name
#We could rename the small zones by saying
# smallzones[0].Name = "FIRST-SMALL-ZONE"
# smallzones[1].Name = "SECOND-SMALL-ZONE"
# now we have a problem
# surfaces still refer to the old zone names
# to safely change the name of an idfobject so that all the references are
# updated, we do the following:
modeleditor.rename(idf, smallzones[0], "FIRST-SMALL-ZONE")
modeleditor.rename(idf, smallzones[1], "SECOND-SMALL-ZONE")
# now the zone names are:
zonenames = [zone.Name for zone in zones]
print zonenames
#
# save to disk and look at the file
idf.saveas('bfile.idf')
# open the idf file and search for the string "SMALL"
# You will find all the places where the name was changed
