information that events are tangent helps the Auto Geometry Engine calculate other
dimensions.
You can often tell by looking at the print if events are tangent: tangent intersections tend
to blend smoothly, without a sharp corner.
Smooth, probably tangent sharp, not tangent
For the A.G.E., the tangent mill or arc is assumed to continue in the same direction, and
not double back on the previous event:
