I am experimenting with creation of Toposolid in REVIT 2026 in 2 routes :
a. By Linking the Autocad File itself
b. By using Dataextraction command in Autocad to fetch the X,Y,Z values of the contours as an Excel **.csv file & creating the Toposolid from this file.
In both cases I find the flat base of the Toposolid below the 0.0 default level of the revit template and also this distance is differing in the 2 cases.
Pls guide on this observation....
