Problem with a shaped edges in the model

does anybody know why my model gets shaded in the edges? sometimes its even changes the color of the shading and I don’t know why it’s happening.
I tried to export the whole model to another file but it still happens.

Hello - if the object is a surface or polysurface, try DivideAlongCreases.


It’s not working but thanks for trying

Hello- what is the object? If it is a mesh, try Unweld at 0 degrees, ModifynNormals= yes.


It’s a polysurfice so I don’t know why it’s happening… I tried also the Unweld but it keeps happening

Hello - please export the object to a new file and post it here, or send to if it is confidential, with a link back to this topic in your comments.
