SM1.LSP and SM2.LSP calculate the section modulus of a flat shape that is defined with polylines.

Along the same lines, but a bit more sophisticated in the math department, is a tip from Jerel Walker. Tip #1953 (Calculate Section Modulus of Flat Shapes) contains two AutoLISP files that calculate the section modulus of a flat shape that is defined with polylines. SM1 works with smaller shapes, and SM2 supports larger shapes. You need to know what a section modulus is in order to use this function in your design. Read the source code for information on how to use these utilities-they have some specific requirements. But they sure beat banging on the calculator.
