I am trying to export a pipe network 3D drawing into shapefile, and I am using this following method: "Use ExporttoSDF command, Start a new drawing, then use MapImport to import that .sdf file. I am making sure to create object data during import." Everything works fine but when importing the sdf in the new drawing, the start/end z values of the pipe is replaced by 0, and the the start/end Invert elevations of the pipe is replaced by the values of the original start and end z values. it will be great if someone can help me find a solution to keep the original start/end values in addition to the original StartInvert/ EndInvert elevation when importing the sdf to autocad civil 3D.
PS: I am using Autocad civil 3D 2017.
