Q - question

Section modulus of 2D profiles in AutoCAD.
A - answer The MASSPROP AutoCAD command does not display the value of the section modulus of the selected object. You would need to use AMINERTIA in AutoCAD Mechanical.

To calculate the section modulus Wx/Wy (SMx/SMy) of simpler 2D profiles in AutoCAD you can use the LISP utility CADstudio Modulus.

Its MODULUS command prompts for selection of a closed polyline or a region and calculates the section modulus to the centroid of the geometry. The resulting values Wx and Wy can be inserted into the drawing as a text.

The values are calculated from the moments of inertia and they are relevant only for simpler geometric shapes.

You can download the free Modulus application from www.cadstudio.cz/download

You can preset the multiplication factor for displayed results:
(setq modKoef 0.001)

You can preset the suffix for displayed results:
(setq modSuf " cm^3")
