SUMMARY
AutoCAD can accurately determine the center of gravity (CG) for vehicle designs using the REGION and MASSPROP commands. The accuracy of the CG calculation is contingent upon the completeness of the CAD model, as missing components like nuts, bolts, and surface finishes can lead to significant underestimations of total mass. Users should ensure that all parts and their respective dimensions and masses are included in the model for precise results. Practical testing with physical models, such as cardboard or plywood, can validate the CG location provided by AutoCAD.
