Level elevation relative to project base point is not correct

[sed]

Hello,

A picture is worth a thousand words

Thanks for your help !

Check if your level's Elevation Base is set to Survey Point or Project base point.  It should be survey point to show the correct elevation above MSL.

[sed]

Thanks for your answer.  Level's Elevation Base is set to Project base point so level elevation should be -910mm and not -984mm.  Am i right ?

[Mirko.Jurcevic]

Yes, it should be -910mm.

Are those levels in your model and not from linked model maybe?

[sed]

These levels are in my model.  Could it come from the fact that a dwg larger than 20 miles (33 km) was imported once in the file (it has be deleted since) ?  I know that we get a warning about accuracy of the model with such DWG files.

Are the RDC and S1 Levels in your model or from a Link?

can you attach the model so we can look at it.

HA! I must be illiterate then!  

Seriously though, need more "words" from you or the RVT itself.

Sorry 🙂 Thanks for all the answers

On the picture the RDC level relative to the basepoint is -984mm

But the dimension shows -910mm

Relative to MSL basepoint elevation is 309910mm

Relative to MSL RDC level elevation is 309000mm but -984mm relative to base point

When i set the MSL elevation of RDC to 309910mm to make a test, the RDC elevation relative to the base point is -74mm

For confidentiality reasons, i can not share the file as it is.  If needed i will try to clean it before sharing.

I'm with @hmunsell on this one.  You're pulling the dimension from the Link Level -- not the Project Level.

A picture is worth a 1000 words...

There is no Revit files linked

[barthbradley]

Well, I'm stumped. I can't think of any other explanation

[hmunsell]

a picture is worth 1000 words but a physical copy would be better in this case. Can you post the file so we can look at it?

[sed]

Here is the file !

It will autocorrect when you move position (manage --> position --> relocate project) and unpin project base point, move up by zero. Or just unpin and repin project base point.

Select Project Base Point, Unpin and Unclip  it, and then Right-Click on it an press "Move to Startup Location" from drop-down options.

basically same as @barthbradley  & @martijn_pater said.... i selected the PBP and did a "Move to Internal Origin" before i started.
