assembly_only*, all_models
specify the level of mass properties calculations.
assembly_only - calculates mass
properties for the assembly.
all_models - calculates the mass
properties of all models in the assembly and includes them in a report. when the report is longer than
2,000 characters, it is not shown on screen, a *.m_pfile is written to your working directory. models with no calculated mass properties (quilts, no geometry, or zero density)
are not included in the report.
