I have existing point data for road design, I want to triangulate the surfaces along the route (aligment), because we measure the current point data along the aligment,
so if I can triangulate along the road, the triangulation will be correct and will require less effort. Is there a way to do this?
Are you trying to include the black breaklines in the traingulation?
You still do not understand what I want to explain The program is based on the three closest points when creating a triangle. The program I want is to choose two of the three from the ones closer to the road when choosing these three points.
Actually, what I want to ask is that the program chooses three points that it chooses while creating a triangle by defining a condition.
Be aware, if you manually add new breaklines where only random points originally existed, nearby triangles may reform differently. The only way to force triangles to form a specific way is via breaklines. Any points not used as breakline vertices will form triangles according to the algorithm mentioned in an earlier post, And newly added breaklines can affect the algorithms results.

There is no automated way to do this in InRoads. Your only two choices are the two that you have already identified: create breaklines and swap triangles. Unfortunately, these can only be done manually.
There is a third choice: go back to the field and survey the breaklines. It's an extreme solution but it may be more effective, and less prone to error, than manually trying to correct the situation for a project of this scope.
It has always been a rule that we DO NOT manipulate surveyed data; at ALL. I agree with Ray that those breaklines MUST be collected in the field for a proper design to be accomplished.
