Shared Reference Point - wrong elevation

Hi all,

 

I am trying the shared reference point workflow.  Everything works fine but the revit model is 14.5m too low.

I have tried several points, check the elevations are correct, but the model always comes in at the same wrong elevation.

 

Any ideas what I am doing wrong?  I am an experienced Civil 3D user, but a Revit novice.

No, I missed the associated level with project origin.  Looking through the plans the lowest level I can find is Level 1.  I don't know if that is aligned with the project origin.  How do I check that?

I had a further play around.  I noticed that I hadn't updated the Location to the shared coordinates.  If I update this and export the 3D view, the elevations are closer, but still slightly incorrect.  I am confident that I exported the xml at the right elevation, I am doing something wrong in Revit.

Open an Elevation view and move the Level you have to 0.

So, I grabbed the lowest level which I believe is the level referred to in the base plan I am aligning with my shared point.  I moved this level down to 0.  I repeated the shared point process and now my elevations are much higher.

 

Interestingly, the elevation of the exported dwg is now the expected elevation + the elevation from the shared point brough into Revit.  94.000 + 117.206 = 211.206 (0.1 off)

 

Apologies if I am making dumb mistakes, Revit is very alien to me.
