Converting v5 drawing and part to v4

Hello,

The situation I have is as follows: I am using v5r16 and I only have access to V5 at the moment. A customer requested a part and drawing in v5 which I completed. Now however the customer has requested the part and drawing in v4.

 

The question is: Is there a way without having access or any knowledge really of v4 can I convert/save a v5 drawing and part to be useable by v4??

 

Thanks in advance!

Convert to, yes
Usable, no.

CATParts can be saved as a .model (v4), but it will result in an isolated solid with no history.
CATDrawings cannot be saved to V4, but they can be saved to .dxf, and then the result read into V4. But, again, it will be isolated with no reference to the 3-D.
