Use edge swapping to change the direction of two triangle faces in the surface model so that, for example, the triangle edges match ridges or swales.
To swap an edge, observe the following conditions:
- You must click within 1 unit of an edge.
- Two visible triangles are separated by the edge.
- The edge is not a breakline edge or an edge created by an Add Line operation.
- The quadrilateral formed by the two triangles (which are separated by the edge) is convex.
Tip
To perform this operation, ensure that the surface style has triangles visibility enabled. See Surface Styles and Display.
Tutorial Exercise: Swapping TIN Edges
- In Toolspace, on the Prospector tab, expand the surface Definition collection, right-click
, and click Swap Edge. At the command line, you are prompted to select an edge (line) to swap.
- Click the edge to swap it.
The edge is swapped if the criteria are met. For information, see Swapping Edges.
- Optionally, continue to select edges to swap by clicking them.
- Press Enter to complete the operation.
The edits are added as Swap Edge operations to the Edits list view in Prospector.
