Unique Edges

Checks for duplicate edges - two or more edges connecting the exact same pair of vertices.

Warning Automatic fix: Yes Settings: No Selection: Object

Why this check exists

Duplicate edges create ambiguous topology that can ruin subdivision surfaces and confuse UV unwrapping. These hidden extra lines also waste memory and make models harder to edit. If a duplicated edge also carries a duplicated face, it can additionally cause overlapping-geometry rendering and lighting artifacts — see the Unique Faces check for that case specifically.
