Could someone out there help me find the latest AutoLisp program that calculates properties of plane sections such as polar moment of inertia, moments about various axes, etc. Thanks, Bob

Bob – I just did a browse on "moment" in Lib 2 "AutoLISP/ADS" and up came this: [76703,4204] MOMENT.LSP/Asc Bytes: 4508, Count: 265, 15-Aug-88 Last:02-Dec-91 Title : Calculate Centroids and Moments of Inertia Keywords: MOMENT INERTIA RELEASE 9 AUTOCAD This function calculates the centroid and the moment of inertia for a profile and prints the x and y moment of inertia values. NOTE: THIS IS AN UPDATE to the routine MOMENT.LSP (DL2) that CHAZ HENRY wrote and REQUIRES Release 9. Not a new routine, just a dash of paint added to and old favorite. Note the note!! There are two files called MOMENT.LSP in Lib 2, so make sure you get the newer one which is only four years old (the older one is six). Dave
