Gerry,
I agree with the thrust of what you say - there is no such thing as Terrain Perimeter Elevation.
But, I'm not sure that we are talking semantics here, but I see things a bit differently.
I think of all levels set in relation to chiefs zero floor level - nothing to do with "sea level" - does a negative elevation mean the building is below sea level? - not very realistic.
I can have relative levels (relative to Chiefs zero floor level) by specifying minus levels for below Chiefs zero floor level and positive levels for above Chiefs zero floor level.
I can have absoulte levels by specifying a Pad Elevation at an actual elevation and then terrain levels at actual elevations (but, everything still remains relative!).
If there is any confusion, have a look at the 3 plans I attached in a previous post - no mention of sea level, not a wave in sight (or should that be site).
Oh, one other thing, when you say: "if you have no terrain , terrain level is assumed to be zero, if you have a terrain, it's whatever the elevation data says it is (default 0) , always in relation to 0 (sea level ).
Once again, what has it got to do with sea level?
In these situations isn't terrain level whatever the formula is (eg: -6" - floor thickness below Chiefs zero), and not zero.
I think we are agreeing but just seeing things from a different frame of reference or relativity.
The main point being that I have no confusion about terrain levels and things all work great as they are!Glenn
