The edge condition.In order for the surface to act as a shell the seams between the stripes need to produce a maximum of continuity. The puzzle methapor helps to lock the pieces in place. The NITROS command is elaborate to outlineflatten
OUTSIDE NITROS command: outflattenmesh
parameters are - how many points per arc segment - the more points the smoother the edge.
loops per segment determines how many arcsegments will be fitted between two points of the polygon that is treated.
scale of the arc determines the depth of the connection from a full circle to a straigth line (factor 0 - 1)
Direction(1 or 0) specifies the starting orientation of the arcs.
