Mesh Editing enables you to improve or refine the quality of a mesh and more efficiently create continuous, conformal meshes for large models with multiple parts. You can move individual nodes, merge nodes together, match nodes, or use mesh connections to join the meshes of topologically disconnected surface bodies and solids.

If the nodes on two different parts are coincident (there are duplicate nodes at the same location), it is faster to merge the nodes to join them. If the nodes are at different locations, you should use mesh connections or contact matches.

Mesh Connections work only for sheet bodies, and Contact Matches work only for solid bodies. You can use Node Move and Node Merge for solid, sheet, and line bodies.
