This is driving me crazy, I cannot figure out what is wrong.
I have a very small part that is built in inches (Proe default inch lbm Second units) but I want to report the mass in grams. Proe, however, will not calculate the proper mass.
The setup:
I've set my relations as units sensitive.
I have a SPECIFIC_GRAVITY parameter defined with its units set as g/cm^3, and I have the relation "MP_DENSITY=SPECIFIC_GRAVITY" to set my density from the SPECIFIC_GRAVITY parameter.
I have a "WEIGHT_G" parameter defined with its units set to g. In my post regen relations I have "weight_g = pro_mp_mass"
I have a "WEIGHT_G_man" parameter defined with no unit. In my post regen relations I have "weight_g_man = pro_mp_mass*453.592" (default conversion factor for pounds to grams)
No geom check in the part, no alternate mass defined.
The results:
Proe shows the part volume as 0.003302 in^3.
Proe shows the part weight (lbm) as 0.000132.
Proe shows the value of WEIGHT_G as .000132 also, which is obviously incorrect.
Proe shows the value of weight_g_man as 0.060068, which is correct.
The question:
I cannot for the life of me figure out why the value of WEIGHT_G is incorrect. I've used unit driven relations in the past and they've worked fine. To my eyes, everything is set up correctly.
What can I do to fix this (aside from giving up and simply using the manually calculated parameter)?
