Experience Level: Advanced
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, or open two-dimensional or three-dimensional polylines, but all edges
must be touching to form a closed, rectangular entity. You can use the SURFTAB2
system variable to define the N-direction mesh density of the coons surface.
- Select the first edge for the mesh.
- Select the second edge.
- Select the third edge.
- Select the fourth edge.
Before you can use the Coons Surface command, you must draw four connected linear segments.
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-surface densities with the system variables SURFTAB2, respectively. The minimum value is 2; the default is 6; the maximum value is 32766.
