I have grading style set up to create a cut/fill boundary and the same thing for my corridor. I made surfaces from my grading and corridor and no longer need them. I need to keep the cut/fill lines for my design. How can I extract these lines from these objects? I tried keeping the grading/corridor on one layer and lines I wish to use on another so I can turn pieces of the grading off. However, it will not print the cut/fill boundary without printing all the feature lines created from a grading.
The Daylight Boundary extraction from your corridor:
Select corridor_Contextual Ribbon_Launch Pad_Polyline from Corridor_select near daylight Rt (corridor boundary)
Repeat for left side.
Tip: These will be 3dpolylines. If you desire 2d go to to modify Tab_Design Panel_Convert 3d to 2d polylines.
As for the Surface boundaries (daylight of) they can be extracted by selecting the surface_Contextual Ribbon_Surface Tools_Extract Objects_Uncheck all listed objects except Boundary_OK.
