Creating edge-defined Coons surface patch meshes

You can create a surface called a Coons surface patch, a mesh 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. A patch is a bicubic surface (one curve extends in the M-direction and the other in the N-direction) interpolated between the four adjoining edges. You can select the edges in any order. The first edge you select determines the M-direction of the mesh.

To create an edge-defined Coons surface patch mesh

  1. Advanced experience level
  2. Do one of the following:
  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 mesh.


TIP   To control the density of the mesh, change the value for the Number of M-Direction Surfaces and N-Direction Mesh Density. Choose Settings > Drawing Settings, and then click the 3D Settings tab. Under Change Settings For, select Surfaces. Under Surface Settings, change the Number Of M-Direction Surfaces and N-Direction Mesh Density values. Or on the Settings toolbar, use the Drawing Settings tool () to display that dialog box.
