TOPOGRAPHY & MODEL ELEVATION IS LOCKED?

[ISATyler]

We started the Revit Architecture model before we had actual elevations from a survey so we could do a test fit, etc.

The first floor was put to 2'-0" above the project base point, which would be the approximate location of the sidewalk.

Now That we have survey elevations I know that the first floor is more like 33'-0".  I cannot move the project base point relative to the model, so I moved the survey point down 33'.  Now I can get my level markers to read relative to sea level or to the project base point (i.e. sidewalk), but I can't input survey points to generate the topo.  The survey points should be relative to sea level, but the only option I have input them relative to the project base point.

I can't select and move everything manually in the project up 33', because the model is too far along.

As a workaround, I've decided to just make the topo and then manually move that down 33', but please let me know if there is a better way.

Thanks

1. Select your Level 0 & go to its property & change in Edit Type the elevation Base as ' Survey Point' instead of Project base point.
2. Now go to manage tab ---Under Project Location panel---specify coordinates at a point---Click on the Level 0 line in elevation or section
3. This will pop up a window , enter the new elevation as 33'
4. This procedure will change the Level 0 to Level 33' without moving up.
5. Now you can put your topography points from 33' elevation onwards, it will get created wrt to the Level 33' & you don't have to manually move up & down the toposurface or the levels.
