Sometimes we have "splitter islands" in a roundabout, and I create a only one surface (TOP GRADE code) for that corridor.
The triangulation is going to join with triangles among splitter islands, so I have to remove the lines in the surface.
To avoid that, perhaps I could add a "show" boundary using the alignments of the splitters islands, but I cannot select an aligment for a boundary,it must be a polyline.
I could draw a polyline on my aligment or not removing the polyline if I create the aligment from that object, but I would like to have less entities in the drawing.
So my request is allowing aligment objects for surface boundaries.
