# Edges

Edges are geometric entities representing line segments that form the boundaries of faces included in your model.

In Flow360, edges can be used to:

  • Define specific regions for mesh refinement
  • Control the growth of anisotropic layers
  • Mark important geometric features like leading and trailing edges

# Edge Selection

You can select edges in the geometry editor using selection by clicking on the edge. You can adjust your selection options on the central toolbar.

# Edge Grouping

Edge grouping allows you to organize and manage edges in your geometry. You can group edges based on their attributes such as edgeId, edgeName. The attributes must be assigned in your CAD system.
