I drew 2 lines and added them to a terrain as breaklines.
I then deleted those 2 lines, but their effect on the terrain remains. Since they now don't exist, I can't remove them from the terrain, because I can't click on them.
What should I do here?
If you created the terrain, and the terrain was not linked to the lines, the terrain is independent of the lines i.e. it is created and exists, and does not reference the lines.
Sorry for the hugely late reply.
The terrain was created [From Elements]. I could add or remove elements from the terrain. E.g. If I created a terrain from 3 parallel lines, with the middle one higher than the rest, the resulting terrain would be a ridge. I could then remove the middle line with [Remove Feature] from the terrain and the new terrain would be a flat surface.
Now I face a problem where I have accidentally deleted the middle line. The ridge remains and I can't use [Remove Feature] because that feature no long exists.
Is the only way out to recreate the terrain?
Yes. You will have to recreate the terrain. (If you have consistent data, consider creating a graphic filter, as this would help speed up the process.)
