I'm trying to put down or link on 2D sketch a point in the center of mass of the cross section. Also try to find options to draw / sketch to determine the direction (axis) of the principal planes of section stiffness. A tool that shows the required information is ("Section Properties"). It shows the coordinates (X, Y) mass center section, but calls it the centroid point and displays the angle of inclination of the principal stiffness planes on the global coordinate system. And, behold, this information can not be applied in conjunction points / lines / axes sketch and equations.

Please share your thoughts and advice on how to implement it more automated.
