Coons Surface (3D Mesh)

()

Keyboard: EDGESURF

Creates a three-dimensional mesh with vertices averaged between four edges.

You can apply this command to any four adjoining edges. The edges can be lines, arcs, splines, or open two-dimensional or three-dimensional polylines, but all edges must be touching to form a closed loop.

1. Select the first edge for the mesh.
2. Select the second edge.
3. Select the third edge.
4. Select the fourth edge.

Select the first of four connected linear entities for edge surface: You can select the four edges in any order. Select the first edge. The first edge you select determines the M-direction of the mesh, extending from the endpoint closest to the point you selected to the other endpoint. The two edges that touch the first edge you select form the N-edges of the mesh.

Select second edge: Select the second edge.

Select third edge: Select the third edge.

Select last edge: Select the fourth edge.

NOTE You can change the M- and N-mesh densities with the SURFTAB1 and SURFTAB2 system variables, respectively.

By default, a mesh entity is created. Set the MESHTYPE system variable to 0 to create a legacy polygon or polyface mesh.
