Create a Breakline on a Surface Edge
Create a breakline on the outer edge of a surface when you want to prevent trimming or recalculated triangles on the current surface's edge. The edge breakline is added to the set of members that define the surface, and can subsequently be edited as a linestring. A surface edge breakline reflects a surface limit that you want to preserve. If you add surface members outside of a surface edge breakline, the breakline does not update to include the change, but you can create a new surface edge breakline to encompass the new data if needed.
