I created a project file, and initially left the Project Base Point and Survey Points at 0'-0". My finished floor was 0'-0" as well.
Then I received the .dwg survey file, so I want to create a topo surface and have it in the correct location relative to the building model, and want the contour lines to be accurate as well.
So, I used the "Relocate Project" command under the "Position" tab on the "Manage" menu. I relocated it to be exactly at the actual surveyed finished floor, which in this case, is 5493.58'. And I know that this is the same as clicking on the Project Base Point in a view and manually entering 5493.58'. I left the survey point at 0'-0".
When I attached the survey .dwg, I attached it at the main floor level. If I go to an Axon view, I see that the contour lines in that survey file are way above the rest of the survey lines, and the building model. If I then create a topo surface from the survey, it is created up where the contour lines are, basically twice as high as they should be. So, I have to go into an elevation view and move the topo down by 5493.58'.
That works, except that, the contour lines move, so that when I try to label them, instead of getting a 5490'-0" contour, I get a 5490'-6 31/32" contour. Why don't the contours stay where they are, since in the site settings are set to show contours at 1' intervals starting at 0'-0"? My workaround is that I changed the site settings so that the contours pass through 5 1/32". That moves the contour lines back to the even foot intervals.
Am I not doing this right? It seems that the contours should not have moved...
Thanks in advance for any help...

Hi James
I would create a separate Revit model for the terrain and Link in the .DWG. then I would Acquire the coordinates from the .DWG. this Revit model can then be linked into the Revit building model and again coordiantes can be Acquired. (Manage> Project Location> Aquire Coordinates).
If you have already setup your model, then make sure that before you set the location using the Project BasePoint, that you unlicp it. move the icon to a known position in your model and then re-clip before entering the actual values of that position.
Paul Aubin has written a nice guide on Shared Coordinates :

Hope this helps
