Batch create volumetric surfaces

Based on the topic you mentioned in the first post I created the following:

`#Get net Volume from volume surface

__version__ = '1.0.0'

# 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')
clr.AddReference('AeccPressurePipesMgd')
clr.AddReference('acdbMgdbrep')

    return output

OUT = get_tinvolumesurface_Vol(IN[0], IN[1], IN[2], IN[3], IN[4])

Not the most cleanest code but it is functional. It is however required to have some basic knowledge of python to start with this :slight_smile: .
