Creating edge-defined Coons surfaces

You can create a surface called a Coons surface, a region connecting four edges. You select the entities that define the edges. Edge entities can be arcs, lines, or polylines. The four edge entities must form a closed loop and share endpoints. You can select the edges in any order.

To create an edge-defined Coons surface

  1. Advanced experience level
  2. Do one of the following:
    • Choose Insert > 3D Entities > Coons Surface.
    • On the Draw 3D toolbar, click the Coons Surface tool ().
    • Type edgesurf and then press Enter.
  3. Select the first edge.
  4. Select the second, third, and fourth edges.



Select the entities to be used as the four edges (A, B, C, and D).

The resulting Coons surface patch.
