I want to change bed level of channel using channel Design modification editor tool in geomentic data. I have fixed u/s and D/s elevations and interpolated between both elevations using assigned slope. After doing all these steps, i pressed on Create a Geometry file with these modification buttion and saved with new geomentry file name. However, when i open the file, there is no new geometry and it is showing still old geomentry. Please help me on this issue.
