Today we will see how to create a Toposurface in Revit 2016 from a CSV file. The CSV file could be coming from Civil 3D or any similar application and contains the points that constitute the Toposurface.
The advantage is we can manipulate the points in Dynamo before creating the Toposurface.
In Dynamo use the “File Path” Node to browse to the CSV file. By adding “Import CSV” Node we can get all the coordinates of the points from the CSV file.
Data from the CSV file need to be transposed in order to be ready for creating the points.
After creating the points, the Toposurface is now ready to be created.
