Tip: Creating an N-Sided Surface
The shape of the N-sided patch depends on the geometry of the boundaries to be patched together. For some boundaries, the N-sided patch may produce geometry with undesirable shape and characteristics. For example, bad geometry may occur if
The boundaries have inflections
The angles between the boundary segments are very large (more than 160º) or very small (less than 20º)
The boundaries consist of very long and very short segments
If the N-sided patch does not create a satisfactory geometry, you can either create a series of N-sided patches on a smaller number of boundaries, or use the Blended Surf functionality.
