Multiple Alignment of Adjacent Edges
A face can have two neighboring edges aligned to different curves or edges. This results in conflicting alignment definitions. In the Freestyle Modeling environment, the conflicts are resolved as follows:
Two or more neighboring edges of a face are position aligned.
The external edges to which you want to align the adjacent edges should intersect.
Two neighboring edges are aligned to curves or edges, and at least one of them is also aligned tangent to a surface.
The reference curve of the other edge should be tangent to the external reference of aligned tangent edge at the intersection point.
