How do I make a surface in AutoCAD?

Can we do surface in AutoCAD?

AutoCAD provides two types of surfaces: procedural surfaces and NURBS surfaces. Use procedural surfaces to take advantage of associating surfaces with their defining curves. Use NURBS surfaces to take advantage of sculpting with control vertices.

What is a surface in AutoCAD?

A surface is a three-dimensional geometric representation of an area of land, or, in the case of volume surfaces, is a difference or composite between two surface areas. Surfaces are made up of triangles or grids, which are created when AutoCAD Civil 3D connects the points that make up the surface data.
