HI - model the shape as a solid then you can then run sections in MOI to get the planes but then you have to tab and slot all the sections manually based on material thickness or you can use an old Autodesk product 123d MAKE - export your model out of MOI as an OBJ and import into 123D Make and the slicing and material thickness tabbing is done para-metrically.
