how can i fix this? the naked edges are the outline of the poly surface.
i want a closed poly !
I think i should decrees the smoothness of the lofted curves. Is that right? and how could I do this?
A naked edge is an edge which is associated with only one surface. Based on your image the highlighted edges should be naked edges.
To create a closed volume you will need to add surfaces or move edges. Exactly what to do depends on your design intent.
The apparent gaps between the surface and edge curves are due to the render mesh settings. The render mesh is used for display purposes. An easy way to improve the render mesh is to go to Options > Mesh > Custom > Detailed controls and set Minimum Initial Grid Quads to something like 5000 or 10000.
Thank you very much I get it
