I am trying to find the best way to convert an environment agency DEM .asc file into a CSV format for import into Revit. Is there a way to do this using Civil 3D or any other autodesk products?
you can create a new surface and add the ASC file as a DEM definition. once the surface is built, from the report toolbox, use Surface Points to CSV report.
it appears that hard coding the report path as mentioned in the thread above has fixed the problem. Give that a try, I do not have access to C3D at the moment to run the surface CSV report, but has always worked for me in the past.
*Edit: worst case, after you create the tin surface from asc file, set it to a style to display only the surface points, then extract those points. then you can extract the xyz data from the points.
Im trying to make a surface in revit 2021, but cant figure out how to do it, the way you have explained. how do i create a new surface is it with points?, sorry if it is a stupid question, and where do i make the dem definitions to the ASC file, ?
