G02 / G03 Strange arcs

Hi.
Trying to get some code produced with Dolphin Partmaster to work but getting strange arcs with g02 g03 codes.
Dolphin helped me to modify my post but got even stranger output.

The problem in the first picture is that it is using G2 when it should be G3 and vice-versa. If you were to do a search/replace on the first image (G2 -> WWW , G3->G2, WWW->G3 ) then I think it would look right.

The clockwise/anticlockwise directions are as-viewed from underneath the lathe for a front-toolpost lathe. It may be that the CAM expects a back-toolpost lathe, and there might even be a setting for it. (Or, in fact, it might not matter, I can't decide)

I don't know what happened in the second post. It looks like the arcs have been cut into sections, but strangely.
