0'-0" Topography at -1'-7 1/2"

[craig]

When I place a new topo at 0'-0" in a new project, it's always about 1'-7 1/2" below the first floor which is at elevation 0'-0". Both the project point and base point are at 0'-0" and are located on the first floor plane. How can I get correct this so that the 0'-0" topo is aligned with the 0'-0" first floor?

Toposurface Internal Point Elevations are relative to the Internal Origin of the Project.  

...why would it matter though?  Just place the topo where it should be -- relative to your Project's Levels.

It would be much easier to enter topo points at -6" to have it be 6" below the FF/Top of foundation, rather than entering topo points at 1'1 1/2" for it to be 6" below. So I moved the project base point, the survey point, and all of my levels to align with the internal project point. Now entering topo is a breeze. Thanks for pointing me in the right direction.

I never said to enter Topo points "at 1'1 1/2" for it to be 6" below".  That is a ridiculous workflow -- not to mention, way too much math.   Create the Toposurface and then lower it in Elevation. That's how you do it. 

But, I guess if the site pad is 2000 ft. above sea level -- and your Project's ground floor level -- you could instead leave the Toposurface where it is and raise your building up 2000 ft.  Of course, I'm just kidding.  That's equally ridiculous.
