Unwanted Naked-Edges

[shayan (Shayan Behfar)]

Hi dears
When i want to split my surface with ellipse, unwanted Naked-Edges will appear(as you see in the picture). what’s the reason?split-surface.3dm (133.6 KB)

Hi Shayan - that is the seam point on the ellipse- use MergeAllEdges or MergeEdge to make it all one edge.

Hi dear pascal
thanks for your answer

@pascal

seam point on the ellipse

Is this because of knot on that point?
