Hello all,
Each time that I want to have the toposurface and the building in a single project (as it is easier to manage them) , I have problem with the toposurface, as it comes up from the building elevation (after the acquired coordinates option). So in order to have both in the same elevation I need to move down the toposurface. As a result, the internal points change and it is quite difficult to create the pads or to do any other modifications I need, as the elevation of the internal point has changed.
The only solution in order to have building+ toposurface in the same level and the internal points of the toposurface to be corrected is to separate the toposurface and the building in two separate projects. With this workflow I face a lot of problem with the visibility settings each time that I link the toposurface in the building .rvt.
Is someone that have found any other solution for this problem?
In which case you acquire coordinates in your project? If you have a project that will not be coordinated with others, it is necessary ?
Thank you in advance!
This may help with the problem you are having. It shows how to use sea level elevations for levels and contour labels.

If I acquire coordinates from a link file why I need to relocate the project?.
Also if I relocate the project the diference between toposurface and building remains the same.
It doesn't help me a lot..because in order to create a pad with slope I check the values of the internal toposurface's points.
Honestly, I'm not understanding the problem. First off, the Internal Origin isn't moving and has no bearing. Second, moving the Toposurface to the correct elevation RELATIVE to you Project is the correct procedure. After doing so is when you ACQUIRE Coordinates -- not before. It would be the exact same workflow in reverse. That is, if you Linked your Project/Building into a Site Plan. You would move the Building to the correct elevation RELATIVE to the Site/Toposurface, and then PUBLISH coordinates.

Move you topo up or down to the native elevation before create pads or modify points, when done, move them back together.

Why? That makes no sense. The Pad is relative to a Level. The Topo Infill that is created as part of the Building Pad is relative to the Surface of the Toposurface.
@mairh_tsek : I realized I made a big boo-boo here. Obviously, you have no coordinates to Acquire since you are creating the Toposurface from a PDF. After creating and moving your Toposurface, it's internal points are of little value. Like I said, those points are relative to the INTERNAL ORIGIN. So, if you need to edit the Toposurface to add additional survey points, and don't want to "do the math", then yes, you could move it back to it's Origin Location and then edit Toposurface, and then move it back again. Pretty much what @ToanDN said. The only way to mitigate having to do that, would be to move you Project/Building to the Elevation of the Site Pad. Not ideal. Keep in mind that you can also edit add points to the Toposurface that are RELATIVE to surface (as opposed to ABSOLUTE), which is normally how we do Finish Grading.
FWIW.
Thank you for your answers!
I create the toposurface from a .dwg file which is georeferenced. So when I link it in Revit, I acquire coordinates..and I have the 'problem' with the distance.
As I understand there is not any way (except of the solution of the two separated projects Site & Building) in order to have both topo + building in the same elevation and in the topo to have the correct internal points. Each time I need to move the topo in order to avoid the 'math'.
Could you please explain me why there is this difference? I cannot understand the significant of this..
What workflow do you follow in your projects?
In case that you have a project which will not be coordinated with others models (structural / MEP etc.) do you acquire coordinates ?
Thank you in advance !
You seem to be very concerned about the elevation reading of the Points within Toposurface sketch mode. Most of us aren't. Those Points are always relative to the Project's Internal Origin, and have no value or significance outside of sketch mode. If you were to place a Spot Elevation on that exact Point outside of sketch mode, it's elevation reading would be relative to the "Elevation Base" of the Spot Elevation (e.g. Survey Point or Project Base Point).
