DC function to measure running/lineal feet of non rectangles

[Omarian]

I was thinking, wouldn't it be so much easier in doing lineal measurement to "material" or colour an edge/line and have a function return the length of all coloured edges/lines,in much the same way the the FACEAREA command does? That would be so helpful. I could get the inner and outter running feet by merely colouring the walling footing edges. As I adjust the walls so would the measurements and all the calculations that reference them.
