I think you are already at the XY positions of the skipped arc move. So it would need to be a 360deg arc??

If that's OK then split the move into 2 G03 moves

that is right , 360 is good. but how do I get mastercam to output something that works ?

I have some long code that is too much to edit manually . 

out of the next eight arcs it skipped three of them.

thanks.

Go into the CMD and use the break arcs at 180 or quads and then repost the program.
