anyone??? what does Expr: !r_tr_.is_infinite(*cell_it) mean? it found an 
infinite cell? Im asking cause the .off file was handed to me by a 3rd person 
who exported from a previous .stl file using Blender. Is the model wrongly 
constructed or the .off file might have problems because of the convertion???
