MOve All Levels Down with Project Base Point

I cannot find a post I found in the past that clearly states how to move all levels down at ounce by moving the base point and leaving the Survey Point where it is. I just need to set my 0'-0" point 1" lower and want all the levels, i.e., everything, to move down the 1" also. Please and thank you!

not clear what you mean precisely.  Are you wanting all the Level's to read an Elevation that is 1" less than they do now.  If so, all you would need to do is raise the Level's Elevation Base (e.g. Project Base Point or Survey point). 

 

BTW: Moving the Elevation Base does not physically move the Levels. Only the reference their Elevation is in relationship to.

I could be wrong, but I'd say that you have two options:

link your model to a new site model (if you dont have one), move the linked file down (to a desired level) and then publish coordinates to the model. 

or in a section/elevation use the specify coordinates at point tool, select the level and choose new elevation / level value for the level. All will move up or down.

Obviously it is no longer possible to do this by moving the project point.

Just move Project Base Point 1" up.

That's what I thought I did in the past, i.e., just move the Project Base Point, then change the Levels accordingly. I still want 0'-0" to be at the base point. Thanks all! 

There's a post from @barthbradley in 2019 that I referenced in one of my posts from last October that I'll try to find - it explains it.

If you want the relationship between the levels and the project base point unchanged then just move the survey point.

Thank you, and that's a good solution. IN this case however, I need the survey point to remain where it is so the surrounding grades aren't affected. I moved the based point and adjusted the levels - worked fine.

You have me scratching my head here, @PhilvK. Why are thinking the Project Base Point needs to be Zero Elevation?  The Survey Point is used to correctly orient the building geometry in another coordinate system such as the coordinate system used in a civil engineering application. In the Revit Project, the Survey Point Origin's Zero Elevation is typically representative of Sea Level.  In other words, if your building is being constructed from the ground up on a building site that is 500 feet above Sea Level, then the Survey Point Origin is 500 feet BELOW the base of the building geometry in the Revit Project - no matter where the PBP is located.  Bottom line is that placing the Survey Point on top of the Project Base Point doesn't "correct" anything.  If simply moving the Project Base Point doesn't correct your "issue", then I'm not sure what the issue is.  All I know is that it has something to the Levels' reading 0'-1" too much or too little.  Again, Level elevations are relative to the Level Type's "Elevation Base" which can be either the Project Base Point or the Survey Point.

@barthbradley: I have the Survey Point at 0'-0" so that I can enter topo grades that correspond to the grade elevations on the Civil plan we are using for the project and that's why I couldn't move it. As I mentioned above, I just moved the project base point (finish floor in this instance) to where I need it in relation to the site and adjusted the levels. Seems to be working fine. That should relieve the scratching.

Sorry. I'm still lost here. Your Solution Credit was given to the "move the survey point" suggestion, which you replied to as a "good solution".  Now you seem to be saying that you moved the PBP - not the SP, which is what I told you to do initially.   

 

Whatever. Maybe I need a higher-octane coffee to follow this thread.  😉  

 

Have a good one.

What I meant was that in general, I liked the solution of moving the survey point so everything would follow. It just wouldn't work for my specific instance. Thanks again.
