Add criteria for material list

Civil3D
8

Hi. I’ve using the MapSurface method to map two surfaces for a cut and fill criteria and I get this error.
I think it has something to do with the isMappingCompleted method but the criteria only asks for two surfaces.
Can you guide me in what’s missing? Thanks.

The code in Python is this:

# 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')
