Leo, We also use Zuken Visula for board designs, and had a problem with split planes last year. Zuken issued a bulletin that they were aware of the problem of missing data. A few weeks later they sent another bulletin that they had fixed the problem. Haven't seen it occur again (yet). If you wanted to output everything in a "single" layer, you could use the rs274sl output option. Contact me off-line if you like for other questions. Regards, Roger M.
