Revit, the workflow focuses on topography - BIM

Steps of Toposurface Workflow with Autocad Topography in BIM system

1-Link new Autocad file
2-Set Project location file to Acquire Coordinates
3-Move Project Base Point with clip to new location E/W , S/N
4-Change True North
5-Draw Grid line
6-In site plan parameter change oriantation to true north
7-Move Project Base Point without clip to ax for example A-1
8-Move Project Base Point without clip to level of 0.00
8-1-Move Level to 0.00
8-2-Make Sea Level if needed to Host for Linked autocad
9-Make toposurface from autocad link
10-Make spot coordinate and spot elevation
11-Change survey point without clip  to reference point of Autocad files and toposurface
