Algorithm that creates fillet edge: arc tangent to two edges in the start and in the end vertices. Initial edges must be located on the plane and must be connected by the end or start points (shared vertices are not obligatory). Created fillet arc is created with the given radius, that is useful in sketcher applications. More...

Algorithm that creates fillet edge: arc tangent to two edges in the start and in the end vertices. Initial edges must be located on the plane and must be connected by the end or start points (shared vertices are not obligatory). Created fillet arc is created with the given radius, that is useful in sketcher applications.
The algorithm is iterative that allows to create fillet on any curves of initial edges, that supports projection of point and C2 continuous. Principles of algorithm can de reduced to the Newton method:
