Define reference elevation for points on toposurfaces

When placing points for a toposurface you can chose between Absolute Elevation or Relative to Surface.

Absolute elevation refers to the Project Base Point, however most (all) siteplans we recieve are based on the Survey point. Currently we're forced to calculate all the heights in relation to the Project Base Point.

 

When creating a toposurface, we should be also able to choose Survey Point. So we can input the data directly.

It would make our work a lot easier and more logical.

this is so true! small workaround -> place your points with the same values listed on the site plan, and after you placed them all, select them go to a section view and move them in z direction

I have mentioned to Autodesk directly that they need to give users more options when placing points. The other way of dealing with this is to model the topography at the actual elevation. What I mean by that is if you were to link in CAD topography and instead of moving it down to the Origin Point, you leave it at Sea Level. When you acquire coordinates and create toposurface, the points will be at the elevation you want, but the issue that you will run into is that there is a bug with the label contours. If you leave the CAD link at Sea Level and make the topography based on that, when you label contours via Survey, Project Base or Relative, the values all read the same. They are now aware of this issue and will hopefully address it in the future.

 

I vote for this. Wanted it for years.

Currently topography elements may only be created and edited relative to the Project File Origin Elevation (Absolute Elevation).  Please provide the option, both at time of creation and AFTER creation, to WORK in Coordinates relative to the Project Base Point (PBP) OR the Survey Point (SP).

 

 

I understand we can use Spot Coordinates Labels and Contour Labels to REPORT coordinates relative to the PBP or SP, but we don't have the option, when adding/editing a topo surface by points for example, to specify the points, while editing, relative to our coordinate system of choice.  These numbers are always fixed relative to the file origin, forcing us to: a. create topography in a separate file b. move the topography element vertically to work on it, and then move it back c. do the math manually to calculate the difference, point-by-point, between our Survey or Project Elevation (whichever is being used for project elevations) and the Absolute elevation d. Move all the Project Content vertically to the correct elevation relative to the file origin-- which is usually ill-advised and not always possible to do if using Shared Coordinates.  No bueno.

 

Seems like an uncomplicated upgrade with huge benefits. Cheers!

Just voted up this suggestion.  It's as if the topo tool wasn't thought through properly when it was implemented, or just abandoned half way through.

Few years on from last post, but still same limitation with Revit 2022. (yes I know you can work with Civil 3D surfaces) but for smaller in house projects, topography should have more options and functionality.

Please, please, we need this badly!

I just came back to this thread 5 iterations of Revit later and it still hasn't been fixed.  AUTODESK!  Please fix these little stupid usability issues that are simple problems but that create piles of extra unnecessary work and workarounds.  Please do this before introducing any new features.  (I will write you a list of 100 other small easily fixed small issues...)

6 years and no solution to this!

@bsr04 this has been incorporated into the toposolid tools, and also into the slab and roof shape edit tools. The points can be manipulated based on the Survey Point elevation.
