To Specify or Change the Material Density of a Part
1. Click File > Prepare > Model Properties. The Model Properties dialog box opens.
2. Click change in the Mass Properties line. The Mass Properties dialog box opens.
3. Enter the value in the Density field. Click OK.
The density of the part changes to the new value and the system updates the mp_density value in relations. If a material has been assigned to the part and the value of the corresponding system parameter in relations, its density is updated. Any values dependent on those parameters are updated after regeneration.
 
* The configuration option mass_property_calculate is set to by request by default. Set it to automatic to automatically calculate density.
