What is edges in 3D modeling digital art?

In 3D modeling digital art, edges are the linear connections between two vertices that form the boundaries of faces (polygons) in a 3D mesh, defining the model’s structural framework. They link corner points to outline surfaces—changing an edge’s position or number alters adjacent faces, so artists use edges to refine details (like a character’s jawline) or create smooth curves (like a vase’s neck). If you’re new to modeling, start by adjusting edges in a simple cube (e.g., moving an edge to make a slanted face) to see how they control shape—it’s an easy way to learn basic mesh editing.
