Solves the arc whose start tangent **continues the previous move's direction** and ends at the given point — smooth, gouge-free blends without you computing a centre or radius. The controller derives the centre (on the line through the start, perpendicular to the entry tangent) and the sweep sense from that tangent. Ideal for blending a straight lead-in into a curved wall, or chaining arcs along a contour, where the radius is whatever makes it tangent.
