Hi,
first run command _CONVTOSURFACE, that creates surface objects from your 3D-Faces.
Next start command _SURFSCULPT, that creates a 3D-Solid object ... and that object type can now be modified using boolean functions.
Good luck, - alfred -
PS: please find attached the result I did using AutoCAD 2016
