I have a very complex cad file solid in STEP format. If i calculate the inertial properties of the solid from its geometry by providing custom mass, how accurately it calculates volume of the solid to find out density and other inertial properties like MoI, PoI, CoM?

It appears that MATLAB documentation does not give details about the process of calculating these values from geometry. However, it mentions that if the information is available in the input file itself, then it will directly use those values: https://www.mathworks.com/help/physmod/sm/ref/filesolid.html

I think in that case, you might need to compute the values with some other benchmark software and compare the values with what MATLAB calculates. That will give some idea about the accuracy. MATLAB documentation does not seem to provide any detail about the calculation process.
