Calculates and prints geometry statistics of the selected lines.
Calculates and prints geometry statistics (length, centroid, moments of inertia, etc.) associated with the selected lines. Geometry items are reported in the global Cartesian coordinate system. A unit density is assumed, irrespective of any material associations [LATT, MAT]. Items calculated by LSUM and later retrieved by a *GET or *VGET command are valid only if the model is not modified after the LSUM command is issued.
