It seems Solidworks16 gives me different values for the mass properties for model and flat pattern.

I have a simple metal part with one jog. Material is defined by myself only spec missing is compressive strength, material damping ratio. It has all required parameters to get a mass of metal.However flat pattern has lower mass and volume than it should. Why is that happening? I can't do proper mass calculation.


Normal model   8.1610 g

Flat pattern  7.9928 g


Volume normal 896.0576 mm^3

Volume flat pattern  914.9071 mm^3
