  1. Hi, To Determine Moments of Inertia Ixx and Iyy: Following conversion of objects into unions, I usually run MASSPROP to determine the centroid location, use UCS>Origin to move the UCS to the centroid and re-run MASSPROP to find Ixx and Iyy. During this procedure, I have to say no to write to file twice, divide the given Ixx and Iyy by 10x10x10x10 or 10000 to have the units to cm^4 and add cm^4 and do stacking at the end. Hence my search for a lisp that can automatically do the above and convert the Ixx and Iyy results from mm4 to cm4 and add cm4 (with stack) at the end of the results even coloring the results to a given color for emphasis. I have also found a lisp called modulus.vlx that calculate section modulus. However the results are in mm3 but the program add cm3 to the number. I want true cm3 results in spite of having drawn everything in acadiso.dwt and with mm units. Thanking you in advance, Regards, Nicolas.
