How to access raw voxel data

[reconlabs-sergio]

I'm succesfully generating voxel meshes with the voxelize.py scripts. However, I'd like to acces the raw voxel grid in whatever form it exists. Is this not exposed?
The output of grid.raw_grid.__dir__() is

['__init__', '__doc__', '__module__', 'insert_mesh', 'create_grid', 'erode', 'dilate', 'remove_cavities', 'get_voxel_mesh', '__new__', '__repr__', '__hash__', '__str__', '__getattribute__', '__setattr__', '__delattr__', '__lt__', '__le__', '__eq__', '__ne__', '__gt__', '__ge__', '__reduce_ex__', '__reduce__', '__subclasshook__', '__init_subclass__', '__format__', '__sizeof__', '__dir__', '__class__']
