Spot elevation giving wrong value of pipes?

[Anonymous]

Hello,

I'm designing a piping system and I'm putting spot elevations annotations at the connections. I'm using "current level" as relative base to show the distance from the floor to the top and bottom parts of the pipes. For some reason it gives me a number that is 55 mm less than the actual height. I tried with my colleagues computer on a completely different project and he has the exact same problem, also 55 mm difference. How could this be? I assume it is something general as we both had the exact same difference in height. We use Revit 2017.

Thanks!

@Anonymous What is the justification of your pipe? Also did you set your spot elevation to read Top or Bottom of elevation? Did you set your view to fine?

I realized that there were two "layers" of levels in the model in which one "layer" was a few mm higher than the other. I just had to change the reference level. Simple as that. Funny that my colleague had the exact same problem and we still couldn´t figure it out...
