exporting from c4d to max

[Gili c]

Hi all c4d users

I'm using max and recntly i've recived a 3ds file which origanly created in c4d , i've got it a little massed up , some of the top and buttom polygons of each mesh came as seperate objects and not attached to the mesh

I'm not familiar with c4d but what is the best way to export it to max?

Thanks on advanced
