AutoCAD Civil 3D Help: Surfaces

曲面

This chapter covers Civil 3D Surface objects, and how to work with them using the AutoCAD Civil 3D .NET API.

There are four classes of surface in Civil 3D:

• TinSurface
• GridSurface
• TinVolumeSurface
• GridVolumeSurface

The first two represent a single layer of terrain, while the second two represent a volume between two layers. All four derive from a generic Surface object, which exposes the common methods and properties shared by all surfaces.
