When feature lines within the same site cross each other and create a split point, that point acquires the level of the feature line that was last edited, which is commonly known as the “last one wins” rule. If the other feature line has a different level, it gets a gradient break at the crossing point.
If a site contains feature lines of different styles, you can specify a priority level for each style for the purpose of controlling split point levels. For more information, see About Feature Line Site Properties in the Grading chapter of the User’s Guide.
There is not an actual point at split points, so you cannot directly edit the level. When you edit one of the feature lines, its gradient runs straight through the intersection, forcing the other feature line to break at the split point. If you create a feature line from AutoCAD elements, without assigning levels, the new line has a default level of zero (0). To edit the level of a split point directly, or have better control over the point, use the Insert PI command to create a permanent point at that location on one of the feature lines.
