Removing / deleting embedded fences, roads, etc

I haven’t been able to find any documentation explaining how to remove or edit specific Landshape elements once they’ve been added - for example, a road or an embedded fence.

Right now, the only method that seems to work is using “Undo,” but that’s not practical if you’ve made a lot of progress or are returning to the model a day later.

Could someone please clarify the proper workflow for:

  • Deleting or removing a road that’s already been created
  • Removing or changing the shape of an embedded fence
  • (and possibly other elements that get baked into the terrain)

Any guidance or best practices for editing or managing these elements after creation would be really helpful. Thanks!
