Fill a hole in a mesh of the size of a single triangle

[mbernard]

Good morning all,

I have a mesh (triangular type : STL file) which has a hole of the size of a elementar triangle.
I filled this hole with the pencil tool. This works perfectly as i can't see no longer behind the triangle but the outline of this triangle still appears when I apply shading on all the model.

How to proceed to no longer see this triangle?
Thank you in advance.

Make sure the face orientation is correct. Blue back face toward the inside of the volume. Then soften the edges by clicking on them with the Eraser tool while holding Ctrl.
