Set ProfileView Band profile 1 or profile 2 to new profile

Civil3D
,
10

Back in the day (as python and dynamo newbie, so it is messy) I was experimenting with this without succes.
I remember it ran without warnings, but it did not set the profiles as it should have, and it made the profile views buggy as well. All show label ticks disappeared for some reason, thus the show label part in the code, but after the first run the views got buddy and the labels always disappeared. So here’s that code, but use it at your own risk:

# Load the Python Standard and DesignScript Libraries
import sys
import clr

# Add Assemblies for AutoCAD and Civil3D
clr.AddReference('AcMgd')
clr.AddReference('AcCoreMgd')
clr.AddReference('AcDbMgd')
clr.AddReference('AecBaseMgd')
clr.AddReference('AecPropDataMgd')
clr.AddReference('AeccDbMgd')

						pvbsiex = pvbsi.Item [1]	
						pvbsiex.Profile1Id = spId

				t.Commit()	
	return pvtsi
