ive imported a civil 3D file into ORD. the linework show up as line strings. how do i convert them into ruled feature lines, and keep the 3D elevations?
Did you import them into a 3D file? Survey data must be stored in a 3D file to preserve the elevation data. This is different than design information, where the 2D data is assigned elevations using the profile tools.
If it was processed somewhere else and that platform supports LandXML, you could import the LandXML terrain into Open Roads and use the 2D linework as background
