Since no one is going to bother to read this post anyway, I can say what I want.
LET me attempt to clear up some of Scott's confusion and some others.
There is NO such thing in chief as TP (Terrain Perimeter) elevation. So there is nothing to set. All references are (fixed) to 0 -- assumed to be sea level. It CANNOT be changed. This has been explained before and generally does not cause a problem except to surveyors and builders who usually reference to a local marker. 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 ).
Pad elevation is related to wherever the center point bottom foundation level is to its location on the terrain surface. And is given in relation to 0 - sea level - explained before.
Contour elevations are +- to sea level 0.
Everything is Okey-Dokey unless you get surveyor's data referenced to a local Surveyor's marker level, thus the confusion between sea level and elevation data. You CAN NOT bias the 0 point (sea level).Gerry

Yes, t.p. can be changed very easily. The contour lines stay the same though.

D. Scott,
I have been away for a couple of days and come back to this very interesting conversation.
Can you explain what you mean in the above by
ELEVATION OF THE TERRAIN PERIMETER - is there such a thing?
and TERRAIN ELEVATION - is there such a thing? Do you mean Pad Elevation?
In your example I would set the Pad Elevation to 20' (relative floor level) - is that what you want to know?
What are you trying to achieve?
Haven't we been through this before?
I think a lot of confusion arises because when you have a Terrain Perimeter with contours and you uncheck Auto Calculate Elevation.
Under these circumstances Pad Elevation is the elevation you are setting for Chief's zero floor level to - it has nothing to do with setting terrain building pads or elevation regions under the house - or nothing else to do with shaping or modifying the levels of the terrain.
It simply relates zero floor level to the terrain levels.Last edited by Glenn Woodward; 01-21-2012 at 05:55 PM.

D. Scott,
I have attached 3 simple plans showing Relative levels (auto calculate floor height), Real World levels (auto calculate floor height) and another showing relative levels with a specified floor height.
PS
One of the plans was corrupt.
I have reattached for those who are interested.Last edited by Glenn Woodward; 01-28-2012 at 02:06 PM.

I can change the terrain perimeter all day long. Open DBx and change. I can put terrain above house or below, keep in mind that my one stry house elevation is staying at 0.0.
Scott:
when you change the "pad elevation" you are changing the HOUSE
not the terrain

Much ado about nothing...
David:
sorry but since there is confusion it should be discussed to try and resolve that confusion
if the confusion is left unanswered then future readers will be confused or mis-lead etc

Hmmm, I tried that before and I just tried again
they don't change at all ???
too tired - I"ll try again in the morning

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

Glenn:
chief's manual discusses sea level
in the real world all absolute terrain data is based on sea level
by default chief works with relative height values for the terrain elevations (set via elevation data such as regions)
then it auto-calcs the "pad elevation"
when auto-calc is off and a "pad elevation" is entered that value is an absolute value per sea
with auto calc on the house "rides" the terrain like a BOAT
the house elevations are relative within the BOAT, yet the boat is at an ABSOLUTE value in relation to the elevation data
and the "pad elevation" per sea level
with auto calc off the connection between the house and terrain is broken
after that each MUST be set separately
if the elevation data (such as regions) is changed and the "pad elevation" is left at zero the house remains at sea level
with auto calc off and adding no elevation data (such as regions) the TP will remain at its default of 0" sea level
change the "pad elevation" to 50' and the house will be in the air at 50' above sea level
read the sea level references in the manual
