It is vague "polyline bulge"; how it is in Arc form - center, radius, start and end angle?
In 0,7.5,A1 - 1 is in the same unit as 7.5 or percentage - A1 always means 180 degrees?
Very thanks for editing Wiki!
How are denoted full circles? 360 degrees -  tangent of 1/4 of the arc is tangent 90 degrees, it is infinity
