Whenever I have a problem like that, I try to describe both states with the same formula and figure out what factors I can interpolate to get smooth in-between states. Asking for help, clarification, or responding to other answers. To learn more, see our tips on writing great answers. That means we want to define a line segment, a pivot point and then bend the line at that point. The closer it is to being straight the smaller the angle around the circle has to be. The circumference can be found by multiplying PI (3.14159) times the diameter. Segment: A part of the circle separated from the rest of a circle by a chord. I am a software engineer interested in computer graphics, physically based rendering and real time graphics. Since your second control point and your endpoint are identical in both cases, you get a straight line, but no curve. The following works out perfectly: $$\text{arcLength} = \text{bendFactor} * 2\pi$$. Line to Arc does not convert arrow lines, dash lines, dash dot lines or hatch lines.
