or just have a bunch of stepped walls

That's my thought as well. Right now in order to do it I either have to factor the slope and do every section of wall as an independent section rather than a continuous operation

I think that this would help in the 3d rendering. This would be helpful in lots of different aspects (i.e. top of wall, bottom of wall, flatwork grade breacks, etc.)

Yes I would like the option (like verify on planswift) to input and record an elevation at every click point.
