Detailed Description

A blockEdge defined as an arc of a circle.

The arc is normally defined by its endpoints and a point on its circumference, typically a midpoint. For example,

points ((1 0 0) (0 1 0));

arc 0 1 (0.707107 0.707107 0);

The arc can enclose an angle greater than 0 and less than 360 degrees.

The arc will frequently enclose an angle less than 180 degrees. For the case, it is possible to define the arc by its endpoints and its centre (origin) point. For example,

arc 0 1 origin (0 0 0);

When defined in the way, any discrepancy in the arc radius for the endpoints is resolved by adjusting the origin to ensure that the average radius is satisfied.

It is also possible to define a flatness factor as a multiplier of the calculated radius. For example,

arc 0 1 origin 1.1 (0 0 0);
