DXF is great for re-creating PCBs but for schematics a print out and highlighter pens are your friend. Tried it, but you end up with so many lines on the screen, it can be confusing.
That is the crux of the problem, if both systems follow a strict set of rules for footprints such as IPC-7351 standard then life can be a little easier, BUT you cannot guarantee that, and I have never yet seen a perfect match between one system and an other, even within the same company, though some come pretty close. When using netlists between different PCB/Schematic packages always seems to involve some hassle, even down to characters used and ascii characters allowed in net, part or symbol names.
Moving toward one glabal footprint library (IPC-7351) is the first step to being able to do cross platform schematic/PCB work.
