Hey Community,

i have a file in which "weird" lines occur if i export as .obj .stl .3ds and so on. I reall tried them all.

I need to export it as smooth surface as possible and import in blender.

Please have look at the attaced file.

I want that the lines near to the stripes (booleaned stripes) do not occur. It kills the smooth surface.

I am very thankful for every help !

Thank you so much
