Hi Dan,
If I understand you correctly, I think you need to include a line in your NC setup|conversion window, that will remove the Y values from your lathe postings:
Original:
{Y-*[0-9]*.[0-9]*}
The corresponding line in the
Convert to:
window, just leave blank.
Make sure your lathe drawings are in 2d mode, so that the entities are not placed in some screen Z plane other than Z0.
