I thought I could simply define the coordinates of the survey point without it actually moving a thousand kilometers away?
because that is what it does, ...??
Thanks!

That is what it is supposed to do! If you change its coordinates, it will move to the new ones
If you intend to setout your project sometime late into the project, i believe it would be better to use one of the following (under manage >> Project Location)
After you relocate the project you may unclip/relocate/clip the survey point

Thanks @RDAOU ,
we are just planning our standard workflow, that is the file preparation, where we import dxf site plan and the topography points.
I thought that I could sellect the survey point, and tell it: be 473888.437,5408362.832,566.459, without having to travel anywhere.
When it actually moves into the 3D space, I ruin all my pre-set levels and views...
@Anonymous
It depends on when you are relocating the project...early or late . If you always expect your site survey data to arrive late during the design stage, you can always set up the levels datum to report to the Project base point. (Chech the below YouTube example...relocating building and levels not effected)
what gives more flexibility is how you set up your site (1 model site and building or 2 models 1 for site and 1 for building)

What's the purpose of moving the Survey Point? Are you wanting to move the SP Origin as well?
@barthbradley @RDAOU actually what I want to do is quite simple, in principle:
1- I prepared the project template with all views centered around a single family house dummy
2- I want to insert the Kadaster plan, to fit in my views, but with maintaining its correct coordinates (I would move the DWG attachment but dont want the coordinates to change) - I extracted the coordinates from the plan itself, but it did not allow me to move it around)
3- I want to create topography from the points file. It generates the terrain, but its positioned 20m away horizontally, and vertically, even though I typed in the height of the survey point as (-)566m it still creates the terrain 566m above the project level:
here: I have the EFH level set based on the survey point, which i moved (can see it to the left). but the level value is still 0.00
Do the "Z" values in the Point File represent an Elevation/Altitude above Sea Level?
If so, leave the Survey Point/Origin at the Internal Origin of the Project.
Create your Toposurface from the Point File.
The Survey Point/Origin is now representing Sea Level.
If you what to lower the Toposuface, go to Elevation View and move the Toposurface AND THE CLIPPED SURVEY POINT together. Now, the Survey Point/Origin is still representing Sea Level. You could, at this point, even place a Level (that has Elevation Base set to "Survey Point") through the Survey Point and name it "Sea Level" so that you have a Sea Level that you can reference when placing "Relative" annotations.

Something doesn't make sense, sites Change from one project to the next...why would you insert a Site/Kadaster into a Project Template?
Regardless of how big or small your projects are, Site and Building should be managed in two separate models.
Don't need to mess up you current workflow thou, so I wont add more to this post...Bart there is the master of such big topics so I leave him to guide you through it ![]()
Prost

Thanks @barthbradley @RDAOU for your patience, maybe working on 2 seperate files is a good idea, generally the goals are:
-the imported data are positioned automatically in their correct x.y.z position,
-the position of the project remains more or less centered within the template's pre-set sheets,
-and that spot elevations report sea elevation...
I assumed that when I modify the x,y,z position of the survey point, Revit will understand where to place every future imported data correctly?
for some reason however even the x,y position of the imported terrain is shifted ![]()
I attached the files I used, would appreciate if you took a look.. many thanks!
I start from here:
Attached the kadaster plan, then acquired from it the coordinates, the survey point disappeared
however, I now assume that the kadaster plan is correctly positioned, so tha when I import another correctly georeferenced plan, it should fit. but it is not doing that. it still consideres the internal point - apparently - as the 0,0,0 and not the survey point. it places the map center-to-center because othewise its a million miles away:
I find the survey point and move it 566 m. downwards. to my understanding it now represents the true global 0,0,0. I try to import the topography points. but again, its not correctly positioned in ALL directions:
I have no idea.. why does revit not use the acquired coordinates when I add things to the file?
