Thought I'd see if anyone has any more comments on this. All of the existing responses seem to miss the OPs actual question. Assuming you have already generated a flat instance (and we show it on our drawing), how do you generate the final DXF file that gets sent to manufacturing? We currently do it the way that the OP does. Create a new drawing, scale 1:1 and save as DXF. Would prefer a way to do it directly from the part file, or better yet, from the assembly that the part is used in.
Ideas?
