Summary: Mass Properties asm W/mixed units

Thanks for the reply's,

After several people suggested the possibly that one or more components had
an incorrect density or default value of 1. I assembled a simple lock
washer (inch) into an empty assembly (metric), ran Mass Properties and
compared the values (way off as I had said). I was about to cut and paste
the results and send it out to show everyone what I was talking about and
bingo (well I had a few other choice words here) there it was. Apparently
someone changed our English start part unit setting to IPS ( Inch, Lbf, Sec
). The density units for the washer was Lbf Sec*2 / in / in*3. My values
were off by a factor of 386 or the value of Gc = 386.4 Lbm In / Lbf S*2.
Set the units back to Pro/E Default ( Inch, Lbm, Sec) and all is fine.

OK... long winded summary maybe but thanks guys for pointing me in the right
direction.


Thanks again,
DJ
