Thanks, Layne. I had been wondering about that myself. And thanks, Marlin523, for asking a question that I keep forgetting to ask.
One follow-up question, though, for anyone. I know how to create comma separated value files in Excel; that's easy. But if I wanted to add a whole bunch of parts into RockSim, what would be the sequence of the values that it would need to have for each record? I can easily set up the spreadsheet, but I need to know what values to input. TIA and Happy Holidays!
