If you are interested in extracting data (inertias for example) you can do so with a BMX analysis feature called an Excel Analysis. This feature basically is intended to return only one number to ProE but but you can use many paramters as output from ProE to the spreadsheet to generate that number. If you don't want any number returned to ProE then you just allow it to return a dummy number you are not really interested in and take advantage of the output anyway. Basically your section analysis generates a series of section properties and these are written out to a spreasdsheet. It is done fairly automatically.

If you are interested in using this and it suits your needs then let me know and I can explain further if you can't find it online.
