Hi there,
I have a problem with using the toposurface to generate contour lines. Please see attached.
The surface was made by placing points over an image. The circles mark example problem areas where revit has interpolated between points. The blue lines are both at an elevation of 47000.
From what I've read on forums there is little that can be done about this. I've tried adding extra points and the interpolation only corrects minimally. Is there anyway around this?
To generate accurate site plans, is the best practice to simply redraw the lines in 2d?
Many thanks
Hi Martin,
You draft manually from image to contour line in Revit. For this process, I am suggest you to use Autodesk Raster Design, it can convert from image to vector then you can import DWG result from Raster Design in to Revit.
For interpolated point or area, in Revit site setting you can change the value of interval ( At Interval off) and make it smaller number which can show more contour line. Regarding some point which not consistent , better you assume by yourself with refer to nearest point number around that point.
Here is the link that you can refre to make good practice in term of Revit and Toposurface:

From my point of view, when I want a more accurate representation and especially when I need to work with underground building and works I use not TopoSurface but Mass - In Place Mass..
Here are the steps in a simplified example:
First in Project:
then - Massing - In Place Mass
Hello @constantin.stroescu - I realise this is many years after the original post and your advice, and that you might not even see this query but I thought it couldn't hurt to try and make contact. I have tried and tried all afternoon to follow your instructions and images but have had no success - unable to modify the spline lines, close the loop or even create the mass. I am not sure if is my inexperience with massing, or things have greatly changed in Revit - I am using 2020. Can you perhaps offer any further insight into how you form topography from In-Place Massing or if it is worth going down that path? Any advice gratefully received. Thanks. Vicki
