[PowerSurvey v8i SS4] Analyze volume tool missing

Analyze volume tool(Cut&Fill volumes) is missing from Civil Terrain tools in PS SS4. Also key-in TERRAINMODEL ANALYZE VOLUME doesn't work. If Opensite Designer will replace PowerSurvey then it will also miss option to calculate volumes between terrains?
