Featureline editing- how to delete featurelines from a surface definition ?

[jeff_rivers]

I'm building proposed surfaces for sidewalk ramps, and the process I'm following is to use featurelines to model the ramps, then add the featurelines to my FG surface as breaklines.  In cases where the featurelines have arc segments, the surface triangulation is not as good as I'd like it, so I've been using the 'Supplementing factors' settings to try and force the level of triangulation I want, but occasionally it isn't to my liking and I want a 'do-over'.  I want to delete the featureline from the surface definition, then re-add it using a lower mid-ordinate distance.

The surface->breaklines entry in the Prospector will show me a list of the breaklines in my surface definition, but it only shows them by name and number of vertexes.  Short of deleting a featureline and recreating it, how can I just remove a featureline from a surface definition? If I right-click an entry in the prospector, there's an option to select it, but all that does is select the entire surface, not any individual breakline.

LIst the featureline, the output will tell you which surface it is used as a breakline in, if any, and the breakline name. Note the last entry below, it is breakline number 7 in the Pit Entrance Breakline group, of Surface FG

                 AECC_FEATURE_LINE  Layer: "C-ANNO"
                            Space: Model space
                   Handle = 17bf4
              Site : Site 1
             Style : Basic Feature Line
            Points : 4
         2D Length : 83.686'
         3D Length : 83.716'
   Elevation Range : 304.87' - 306.46'
       Grade Range : 0.25% - 4.28%
    Breakline Data : FG, Pit Entrance: 7

delete in plan, then "OOPS"

you can select them fron the site node

Delete then OOPS is super fast and you can add it right back in with the correct supplementing distance that you need. Great answer!
