TinSurface AddLine

[Alexey.Terno]

TinSurface have AddLine function with two parameters - vertex1 and vertex2 as TinSurfaceVertex.

How can I create a new TinSurfaceVertex for using AddLine function?

Just like Adding a Line inside of C3D, you would use the end points of existing TIN lines. If you need to add a line at a random location, use the AddVertex method to add the 2 end points..the TinSurface may create the desired line when adding these, depending on the relationship to the surrounding vertices.

Two new points not always will create a line (triangle edge).

I will check AddStructureLine function... it seems it what I need.

[Jeff_M]

Yes, that's why I said it MAY create the line. You can check if the line was created by usseing the FindEdgeAtXY and passing the midpoint between the 2 vertices you add. If it does not find an edge, add the line.

AddStructureLine? I am not seeing that in the API docs....
