Aligning toposurface to Ground Floor?

Hi guys,

Am currently completing my first project in Revit and am very excited about the future that it will bring.

I have a question in regards to topography created from a 3D survey and how to vertically align it with your house model. I have successfully created the toposurface but it is way above my house.

Would appreciate it if some of you guys could detail your procedure of how this is best done.

 

Regards

Dale

Just grab it in elevation and drag it down. 

 

...I'll bet you're wondering right now.  Probably thinking "if I move it down, then it won't be at it's 'true' elevation".

Hey @Anonymous , did you move it yet? If not, I got a suggestion you may like. 

 

In Elevation, turn on the Project Base Point, unclip it, right-click on it an select "Move to Startup Location".  Now place a New Level through the PBP and name the Level "Sea Level" (I'm assuming Survey Elevations are relative to Sea Level).  Now when you move your Toposurface down, move the "Sea Level" at the same time.   Move them together.   Now you can set up Spot Elevations and Contour Labels you put on the Toposurface to the RELATIVE to this "Sea Level" -- just like the Survey.   All will be right as rain.

Thanks @barthbradley. Took me a while to process what you were laying down but I got there in the end. I like that approach. Will the project base point have to move down with the 'sea level'? What do the spot elevations and contour labels reference in scenario? 

Thanks in advance @barthbradley

Place the PBP where you want.  That's up to you.  Obviously, moving it will change the existing Levels' Elevation reading -- assuming your Levels' "Elevation Base" (under the Level Type Properties) is set to "Project Base Point".   But, I wouldn't move it.  We always plan construction from 0'-0", regardless of the actual "altitude" of the building.

 

Regarding Spot Elevations and Contour Labels that do need to read the actual "altitude", then you use Types that are relative to "Sea Level".   I think these screenshots are self explanatory.  

 

Create a new TYPE:

On placement of the new TYPE in the View:

SUGGESTION: Pull a Dimension between "Sea Level" and your Level 0'-0" and then LOCK IT.
