The download spreadsheets today provide functions to find section properties of shapes either defined by coordinates or selected from a list of shape types.  The section properties found are: area, first and second moments of area about the X and Y axes and about axes through the centroid (parallel to X and Y and principal axes), Ixyc and angle of the principal axes, position of the centroid, and in some cases the torsional constant.
