Hi Michael, thx a lot for your quick response. Here is a small sample: Test-OBJ.3dm with 3 Objects (3 Solids: "Left-Part", "Main-Frame", "Right-Part") and the Test-OBJ.obj export . When I import this .obj file into c4d I get a null-object (which is great) and 3 objects in it ("Left-Part_1", "Main-Frame_1", "Right-Part_1")... hmm ... where is the suffix "_1" coming from? :-) - Maybe I have overseen something. THX!! Best, Robert
