原地形与设计地形

提示词

在同一定位基准上表达原地面与设计地面，二者用不同线型或轻色层区分。挖填范围和数量只采用提供成果，保留已知坡折及标高，不从效果图计算土方。

Show existing and proposed ground on the same reference using different line types or light fills. Take cut-and-fill areas and quantities only from supplied results, preserving known slope breaks and levels without calculating earthworks from a rendering.
