Description
With the fillet command you can connect two lines , two arcs, or one arc with a line(these two objects must have at least one common point either visible, or in their extension) , with an arc with a specific radius. The value of the radius has some restrictions depending the position of the objects. If radius=0 then simply the objects are either extended until they intersect each other in one point(if there was not an intersection point) either trimmed(if an intersection point is visible).
You can also insert fillet arcs at vertex of specified index of a polyline where two line segments meet if the specified radius is enough small to fit into lines.
If the radius is bigger then it is ignored for the specific vertex.
