Edge Edit Panel

Use the Edge Edit panel to alter the connectivity status (topology) of adjacent surface edges, and stitch or split surfaces, replace fillets with corners, and suppress or eliminate redundant edges.

Surface Edge Topology

Edge topology helps control the mesh generation for the surfaces and surface boundaries when using the surface automesher. Edges can have one of three states, each of which has a specific color in the rendering graphics.
Free (red)
The surface edge is not connected to any other surface edge. The mesh generated across a free edge boundary will not be connected.
Shared (green)
The boundary between connected surfaces (sometimes referred to as "stitched together").
The mesh across a shared edge will place nodes along the surface edge, and such nodes will be common to the elements on each side of the boundary. Shared edges are further classified as manifold (exactly two surfaces meeting at a common edge) or non-manifold (yellow), where more than two surfaces meet at a common edge. For the sake of simplicity, shared manifold edges are simply referred to as "shared" while shared non-manifold edges are referred to as "non-manifold".
Suppressed (blue)
A manifold shared edge will be disregarded by the meshing process, in effect making a single larger surface out of two individual surfaces.

Topology Display

When entering any panel where the primary function is editing geometry, the surface topology display mode is activated by default. In this mode, the surface edges are colored according to their topology state. The default color assignments are red for free edges, green for shared edges, yellow for non-manifold edges and a blue dotted line for suppressed edges.

Subpanel Organization

You can move freely between subpanels. Your work on one subpanel will not be lost if you switch to a different subpanel. However, similar settings will not be shared between subpanels, so for example changing the cleanup tolerance in one subpanel does not change it in any of the others. In some cases, changes will be reflected immediately in your model as you select edges; in others, one or more green command buttons on the right edge of the subpanel can be used to execute the function once all criteria have been specified.
