Hard and soft break lines

It would be great if LDT distinguished between a hard and soft break lines.

A hard break line would be like a curb or wall. Contours at hard break lines would have a sharp angle.

A soft break line would be like a swale, top of slope or grade break. Contours at soft break lines would be rounded based on the smoothing options set in the contour style.

An aerial topography company that I worked with years ago had this ability in their software. Unfortunately, I do not recall the software name. It was not AutoCAD based.
