Section Properties

A long time ago in a galaxy far, far away I had some kind of ACAD tool that would allow me to draw a section of an aluminum extrusion and once I pedit it into a polyline it would give me the section properties on it, like weight per foot, I values for both x and y axis, perimeter dimension, etc...in a nice little table. I have a need for something like this now and was wondering if anyone knows where I might find information. When I was using this it was with ACAD 10 and I don't remember if it was a LISP routine or what....this was about 1994 as I recall.
