Hey William,
Here's a good site that might help, http://peach.ease.lsoft.com. Look into their archives. I posted a couple of questions about this matter at this board, I received 1 reply. Needless to say I'm teaching myself how to get VW to put together an estimate as I draw. I'm in the middle of the project & it looks promising. I'm using two components of VW (1. records, 2. database worksheets) and exporting to Excel. I'm more comfortable with Excel for setting up a spreadsheet. Like I said, I might be 1/2 done but each step forward sometimes puts me three steps back. I'm not a puter geek but if I can help, you are welcome to e-mail me questions or suggestions.
Have Fun
