You can use up 3 levels and a total of 65535 (2^16-1) combinations. -- Regards,

Sometimes the graph is unimportant if, for example, you're doing a Monte Carlo analysis. Then all you want is the exported data for post-processing. 10,000-20,000 steps is not an unreasonable step count for situations like that. -- Regards, Tony |
