Civil 3D Surface Analyzer Skill

Purpose

The Civil 3D Surface Analyzer Skill performs terrain surface analysis including slope analysis, cut/fill calculations, drainage analysis, and earthwork quantity computation.

Capabilities

• Surface analysis (slope, elevation, contours)
• Cut/fill volume calculation
• Drainage analysis
• Corridor modeling
• Cross-section generation
• Earthwork quantities
• Surface comparison
• Watershed delineation

Usage Guidelines
