If two pipes cross at a location and the clearance node is generated, you want to know the elevation difference between the top of the lower element and the bottom of the top element? I am not sure of a way Clash Detection can calculate this but I can certainly look to see if it is possible.
The Element types and properties are specific to the DGN file formatting, so I don't think you can extract any sort of element to DWG. The rules and coding doesn't exist in the DWG format. This is the same with all types of OpenRoads elements.
